    Selection of maintenance strategy for aircraft systems using multi-criteria decision making methodologies2010Ingår i: International Journal of Reliability, Quality and Safety Engineering (IJRQSE), ISSN 0218-5393, Vol. 17, nr 3, s. 223-243Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper, proposes the Multi-Criteria Decision Making (MCDM) methodology for selection of a maintenance strategy to assure the consistency and effectiveness of maintenance decisions. The methodology is based on an AHP-enhanced TOPSIS, VIKOR and benefit-cost ratio, in which the importance of the effectiveness appraisal criteria of a maintenance strategy is determined by the use of AHP. Furthermore, in the proposed methodology the different maintenance policies are ranked using the benefit-cost ratio, TOPSIS and VIKOR. The method provides a basis for consideration of different priority factors governing decisions, which may include the rate of return, total profit, or lowest investment. When the preference is the rate of return, the benefit-cost ratio is used, and for the total profit TOPSIS is applied. In cases where the decision maker has specific preferences, such as the lowest investment, VIKOR is adopted. The proposed method has been tested through a case study within the aviation context for an aircraft system. It has been found that using the methodology presented in the paper, the relative advantage and disadvantage of each maintenance strategy can be identified in consideration of different aspects, which contributes to the consistent and rationalized justification of the maintenance task selection. The study shows that application of the combined AHP, TOPSIS, and VIKOR methodologies is an applicable and effective way to implement a rigorous approach for identifying the most effective maintenance alternative.

    Prerequisites for a business-oriented fleet availability assurance program in aviation2010Ingår i: Proceedings of the 1st international workshop and congress on eMaintenance, Luleå: Luleå tekniska universitet, 2010, s. 168-175Konferensbidrag (Refereegranskat)
    Abstract [en]

    The air transport business is a large, integrated, automated and complex domain with high requirements on safety, security and dependability. In order to achieve customer satisfaction and gain a global competitive advantage, provision of services is essential. In air transport business with an extensive competition, the consequences of unreliable services become more critical which may increase cost of operation and reduce productivity. Furthermore, occurrence of unreliable services might also lead to annoyance, inconvenience and a lasting customer dissatisfaction that can create serious problem with regarding the responsible company‟s marketplace position. Hence, it is crucial for air transport companies to continuously improve the quality of the services they provide to customer. In the context of air transport, maintenance process and maintenance-related services have a high impact on effectiveness, productivity and costs. Maintenance departments are required to ensure that their fleet is expected to meet, or continues to meet, airline‟s established availability performance goals (e.g. operational readiness, dispatch reliability and cost affectivity) and to ensure that demands for deliveries will met. One way to align maintenance decisions and business objectives and at the same time highlight where the potential weakness in the systems and maintenance performance can be expected, is through Fleet Availability Assurance Program (FAAP). However, an effective implementation of FAAP needs adaptation to the usage context. Hence, the purpose of this paper is to present an availability assurance program in airline industries, in which the essential functional elements of such a program are discussed. The paper also proposes an integrated information logistic infrastructure for this management system.

    Information security in e-maintenance: a study of Scada security2012Konferensbidrag (Refereegranskat)
    Abstract [en]

    eMaintenance solutions are spreading increasingly due to the continuous evolution in the different Information and Communication Technology (ICT) tools. In general, most of the available eMaintenance solutions are depending on Internet infrastructure what makes them vulnerable to all security threats that affect the Internet. One of the important eMaintenance solutions is Supervisory Control and Data Acquisition (SCADA) system as it has been used in most of the industrial processes. SCADA systems were designed without security considerations as they were mainly installed into isolated networks. Nowadays, SCADA systems are mainly connected to Internet and other networks. Therefore, SCADA systems have been exposed to wide range of network security threats. Hence, SCADA security has become an important aspect that needs to be investigated. In this paper, a study of SCADA security issues will be done. The main contribution of this paper is to address SCADA security issues and challenges related to eMaintenance.

    Model-based security system for data acquisition in e-maintenance using artificial immune system and cloud computing2012Ingår i: International Journal of COMADEM, ISSN 1363-7681, Vol. 15, nr 4, s. 26-37Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    eMaintenance solutions are extensively used by the industry today. eMaintenance is an emerging technology aimed to support the industry to achieve effectiveness and efficiency in their maintenance process through enhanced use of Information and Communication Technology (ICT) . One of the essential components is an eMaintenance solution is data acquisition. Supervisory Control and Data Acquisition (SCADA) has been used to manage data acquisition is many industrial systems. Nowadays, modern SCADA systems are available through internet and other networks via IP protocol. An increased use of internet–based solution requires appropriate management approaches to improve the safety and security aspects of a system. Hence, this paper suggests a new security model based security for SCADA systems through Cloud computing and Artificial Immune System (AIS). Furthermore, the paper provides AIS, which is based on Decision Tree (C4.5 algorithm) using clustered feature set. The features set are selected from NSL-KDD cup. It is a new version of KDD dataset. As a result, two Antibodies are generated (that could recognize Normal and Antigen). After applying the resulted antibodies on the testing data set, the outputs are Normal, Antigen, and Unknown. Finally it is treated with Unknown as Antigen. As a result, high accuracy of the suggested model reaches 96.3%.

    Improvement of Railway Performance: A Study of Swedish Railway Infrastructure2016Ingår i: Journal of Modern Transportation, ISSN 2095-087X, E-ISSN 2196-0577, Vol. 24, nr 1, s. 22-37, artikel-id 2Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The volume of rail traffic was increased by 5% from 2006 to 2010, in Sweden, due to increased goods and passenger traffic. This increased traffic, in turn, has led to a more rapid degradation of the railway track, which has resulted in higher maintenance costs. In general, degradation affects comfort, safety, and track quality, as well as, reliability, availability, speed, and overall railway performance. This case study investigated the needs of railway stakeholders responsible for analysing the track state and what information is necessary to make good maintenance decisions. The goal is to improve the railway track performance by ensuring increased availability, reliability, and safety, along with a decreased maintenance cost. Interviews of eight experts were undertaken to learn of general areas in need of improvement, and a quantitative analysis of condition monitoring data was conducted to find more specific information. The results show that by implementing a long-term maintenance strategy and by conducting preventive maintenance actions maintenance costs would be reduced. In addition to that, problems with measured data, missing data, and incorrect location data resulted in increased and unnecessary maintenance tasks. The conclusions show that proactive solutions are needed to reach the desired goals of improved safety, improved availability and improved reliability. This also includes the development of a visualisation tool and a life cycle cost model for maintenance strategies.

    Data quality assessment using multi-attribute: maintenance perspective2018Ingår i: International Journal of Information and Decision Sciences, ISSN 1756-7017, E-ISSN 1756-7025, Vol. 10, nr 2, s. 147-161Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The paper proposes a model for data quality (DQ) assessment in maintenance. Data has become an increasingly important since most of the maintenance planning and implementations are based on data analysis. Poor DQ reduces customer satisfaction, leading to poor decision making, and has negative impacts on strategy execution. To improve DQ as well as to evaluate the current status, DQ needs to be measured. A measure for DQ could be an important support for decision makers. Multi-criteria decision-making (MCDM) methods can provide a framework for DQ assessment, however, they are not used in literature for DQ assessment. In order to assess DQ, the attributes or KPIs need to be defined, their hierarchy should be designed and the assessment model is proposed to evaluate these attributes. A case study is also presented in this paper. The study shows that MCDM methods could provide qualitative estimation for the quality of DQ attributes.

    Metadata-Based Data Quality Assessment2016Ingår i: Vine: The Journal of Information and Knowledge Management Systems, ISSN 0305-5728, E-ISSN 1474-1032, Vol. 46, nr 2, s. 232-250Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    High quality data and data quality assessment can support the decision-makingprocess. In the literature, discussions of the assessment process are mainly focused on theoretical approaches to content analysis or on user evaluations. Metadata is important source for quality information in any database system, however, it is not considered for data quality assessment. Metadata contains information that describes the data in a database, including the constraints and the database schema. High quality data can be produced by designing a database system with accurate metadata descriptions. Having accurate and detailed metadata will reduce the errors in data values which can lead to data quality issues. In this study, data quality assessment model is proposed based on both content and metadata analysis. The model is validated by developing an application tool to assess the quality of the data in a database based on the proposed model. The results show that metadata can provide important information about the quality of the database and its adoption can help togive faster, more accurate and user independent assessment of data quality.

    Multi-Criteria Data Quality Assessment Maintenance perspective2014Ingår i: Proceedings of the 3rd international workshop and congress on eMaintenance: June 17-18 Luleå, Sweden : eMaintenance, Trends in technologies & methodologies, challenges, possibilites and applications / [ed] Uday Kumar; Ramin Karim; Aditya Parida; Philip Tretten, Luleå: Luleå tekniska universitet, 2014, s. 153-158Konferensbidrag (Refereegranskat)
    Abstract [en]

    Data quality (DQ) in maintenance has become an increasinglyimportant aspect to many firms as most of the maintenanceplanning and implementations are based on data analysis. PoorDQ has adverse effects at the operational, tactical, and strategiclevels of any organization. Respectively, poor DQ reducescustomer satisfaction, leading to poor decision making, and hasnegative impacts on strategy execution. To improve DQ as well asto evaluate the current status, DQ need to be measured followingthe fact that only what can be measured can be improved. Ameasure for DQ could be an important support for decisionmakers. In order to assess DQ, related attributes should bedefined. These attributes could be related to the data itself, to themetadata, or to the data representation schemes. After definingthese attributes, an assessment model should be used to evaluatethese attributes. The purpose of this paper is to propose a modelfor DQ assessment. Therefore, a study of DQ attributes and thepossible metrics that could be used to measure these attributes wasundertaken. The proposed model will be applied on datasetprovided by the Swedish Transport Administration (Trafikverket)for validation and to find an estimation measure of the DQ.

    Quality of Streaming Data in Condition Monitoring Using ISO 80002016Ingår i: Current Trends in Reliability, Availability, Maintainability and Safety: An Industry Perspective / [ed] Uday Kumar; Alireza Ahmadi; Ajit Kumar Verma; Prabhakar Varde, Encyclopedia of Global Archaeology/Springer Verlag, 2016, s. 703-715Konferensbidrag (Refereegranskat)
    Abstract [en]

    The purpose of this paper is to propose a Data Quality Measurement Model based on ISO 8000 standard. This paper deals about the concepts implied in the measurement process, not about the measures themselves. Poor quality information causes customer dissatisfaction, lost revenue and higher costs associated with additional time to reconcile information. An understanding of the characteristics of the data that determine its quality, and an ability to measure, manage and report on data quality is required. Measurement is a major activity in data quality management. In literature, there are many proposals contributing somehow to the measurement of data quality. However, these measurement methods lack the unification. ISO 8000 provides a framework for improving data quality that can be used independently or in conjunction with quality management systems. ISO 8000 defines characteristics that can be tested by any organization in the data supply chain to objectively determine conformance of the data to ISO 8000.

    Abstract [en]

    Purpose – The purpose of this paper is to explore the main ontologies related to eMaintenance solutions and to study their application area. The advantages of using these ontologies to improve and control data quality will be investigated.Design/methodology/approach – A literature study has been done to explore the eMaintenance ontologies in the different areas. These ontologies are mainly related to content structure and communication interface. Then, ontologies will be linked to each step of the data production process in maintenance.Findings – The findings suggest that eMaintenance ontologies can help to produce a high quality data in maintenance. The suggested maintenance data production process may help to control data quality. Using these ontologies in every step of the process may help to provide management tools to provide high quality data.Research limitations/implications – Based on this study, it can be concluded that further research could broaden the investigation to identify more eMaintenance ontologies. Moreover, studying these ontologies in more technical details may help to increase the understandability and the use of these standards. Practical implications – It has been concluded in this study that applying eMaintenance ontologies by companies needs additional cost and time. Also the lack or the ineffective use of eMaintenance tools in many enterprises is one of the limitations for using these ontologies.Originality/value – Investigating eMaintenance ontologies and connecting them to maintenance data production is important to control and manage the data quality in maintenance.Paper type Research Paper

    Assessment of railway frequency converter performance and data quality using the IEEE 762 Standard2014Ingår i: International Journal of Systems Assurance Engineering and Management, ISSN 0975-6809, E-ISSN 0976-4348, Vol. 5, nr 1, s. 42694-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Reliability, availability and maintainability analysis is one of the most important tools for measuring system performance. The performance of a traction power supply system (TPSS) can be measured using the data collected from frequency converters, as these converters constitute the main part of the TPSS. The quality of the collected data should be good enough to provide the correct and complete information necessary for assessment of frequency converter performance. Many methods can be used to assess the performance of converters such as neural networks, fuzzy logic and standards. The IEEE 762 Standard offers a methodology that can provide key performance indicators for power generation units. This standard has been chosen for its widespread acceptance and applicability. To be able to evaluate a converter’s performance, IEEE 762 indexes should be calculated using data such as the downtime, reserve shutdown hours and service hours. Therefore, the purpose of this study is to assess the performance of the Swedish TPSS frequency converters using IEEE 762, and to assess the quality of data by inspecting their compatibility with this standard. In this study, an application has been developed to generate the missing information and to calculate the indexes provided by the standard, in order to evaluate the power converters’ performance. A case with sample data is also discussed in this paper.

    Aspects of data quality in eMaintenance: a case study of process industry in northern Europe2014Ingår i: Engineering Asset Management 2011: Proceedings of the Sixth World Congress on Engineering Asset Management / [ed] Jay Lee; Jun Ni; Jagnathan Sarangapani; Joseph Mathew, London: Encyclopedia of Global Archaeology/Springer Verlag, 2014, s. 41-51Konferensbidrag (Refereegranskat)
    Abstract [en]

    Increased environmental awareness in the industry combined with the globalized market economy makes increasing demands for sustainable and efficient resource utilization. In this context, maintenance plays a critical role by linking business objectives to the strategic and operational activities aimed at retaining the system’s availability performance, cost-efficiency and sustainability. Performing maintenance effectively and efficiently requires corresponding infrastructure for decision-support provided through eMaintenance solutions. A proper eMaintenance solution needs to provide services for data acquisition, data processing, data aggregation, data analysis, data visualization, context-sensing etc. To en Quality of Service (QoS) in eMaintenance solutions, the performance of both system-of-interest, enabling systems and related processes have to be measured and managed. However, the QoS has to be considered on all aggregation levels and encompass the aspects of Content Quality (CQ), Data Quality (DQ) and Information Quality (IQ). Hence, the purpose of this paper is to study and describe some aspects of DQ in eMaintenance related to process industry in northern Europe

    Data quality in eMaintenance: a call for research2011Ingår i: MPMM 2011: Maintenance Performance Measurement & Management: Conference Proceedings / [ed] Diego Galar; Aditya Parida; Håkan Schunnesson; Uday Kumar, Luleå: Luleå tekniska universitet, 2011, s. 69-73Konferensbidrag (Refereegranskat)
    Abstract [en]

    Effective and efficient maintenance requires a proper information logistics, which can be delivered through eMaintenance solutions. Development of eMaintenance solutions faces extensive challenges. One of these challenges is how to ensure the quality of data used in different eMaintenance solutions. Data Quality (DQ) concerns all phases of the maintenance process. The purpose of this paper is to answer the research question: how should DQ be considered and managed when developing eMaintenance solutions. To deal with such challenges a case study was conducted at a mining company. Empirical data has been collected through interviews, observations, archival records and workshops. The data analysis has been based on an empirical framework that supports the identification of required information services. Conditions that support the DQ and the information logistics, along with that, support the maintenance process have been presented. These aspects have also been related to the phases of a generic maintenance process.

    Abstract [sv]

    Bakgrunden till projektets genomförande har varit den ökande mängden rälsbyten och mängden trafik med 30 tons axellast på Malmbanan. Spårunderhållet och hjulunderhållet har idag de överlägset högsta underhållskostnaderna av järnvägens olika system. Hjulprofilmätaren sågs som en möjlighet att kunna plocka ut de hjul som närmade sig underhållsgränserna för slitage, och därigenom kunna styra underhållet mer kostnadseffektivt.LKAB och Trafikverket enades därför att sätta upp ett gemensamt projekt där en ny typ av mätutrustning utprovades. För att få stöd med datalagring, bearbetning av data mm anlitades LTU och eMaintenanceLAB. Syftet med projektet har varit att undersöka och verifiera att en utrustning för automatisk hjulprofilmätning kan klara av att registrera och larma vid hjulpassager som avviker från de säkerhetsgränser och underhållsgränser som definieras i projektet med hänsyn till vårt klimat och våra förhållanden på Malmbanan. Den bärande idén i detta projekt har varit att man genom en kontinuerlig mätning av hjulprofiler ska kunna ta ut fordon ur trafik innan den avvikande hjulprofilen ger upphov till ett accelererande hjul- och rälslitage och därigenom sänka underhållskostnaden och öka livslängden på både hjul och räl. Projektet har även lett till en högre säkerhet på spåret då man kan mäta hjul som passerat säkerhetsgränsen för hjulparametrar och plockar bort dem, detta var inte var möjligt tidigare. De slutsatser som kan dras från detta projekt är följande:• Utvecklingsprojekt kan med fördel genomföras gemensamt mellan industri, infrastrukturförvaltare och akademi. • För att säkerställa ett bra resultat är det viktigt att genomföra alla steg i ett projekt från koncept till överlämnande. Som stöd för detta har V-modellen används som representerar livscykeln för systemet enligt EN-50126.• Val av tekniklösning och leverantör har gjorts utifrån tekniknivå, referensanläggningar samt drift- och supportmöjlighet och inte enbart utifrån pris. Ett utvecklingsprojekt likt detta handlar inte primärt om att få en utrustning i drift utan överföring av ”know how” kring vilka möjligheter och begränsningar det finns med denna teknik.• Resursbehovet för test och utvärdering underskattades och gjorde att projektet försenades ett år jämfört med ursprunglig tidplan. • Informationen som genereras från denna utrustning är mycket användbar för alla parter som arbetar med utveckling av underhåll inom järnvägen. • Utmaningen för att tillgodogöra sig nyttan från mätstationen ligger i att kunna förädla och integrera de genererade tillståndsdata till respektive underhållsorganisation.

    The wheel profile measurement system at Sunderbyn, Sweden: final report2014Rapport (Övrigt vetenskapligt)
    Abstract [en]

    The background to the realisation of this project comprises an increasing number of rail replacements and an increasing volume of traffic with a 30-tonne axle load on the Swedish Iron Ore Line (IOL). When comparing the maintenance costs of all the different systems in the Swedish railway network, the maintenance costs for the track and wheels are by far the highest at present. The wheel profile measurement system (WPMS) was considered to provide the possibility of picking out wheels approaching the maintenance limits for wear and thereby of controlling maintenance in a more cost-effective way. Accordingly, LKAB and Trafikverket (the Swedish Transport Administration) reached an agreement concerning the initiation of a joint project in which a new type of measurement equipment would be tested. To obtain assistance with data storage and processing, etc., Luleå University of Technology (LTU) and its eMaintenance Lab were engaged in the project. The objective of the project has been to investigate and verify whether equipment for automatic wheel profile measurement is capable of registering wheel data and sending alerts concerning the passage of wheels which deviate from the safety and maintenance limits defined in the project, with regard to the climate and conditions prevailing along the Swedish IOL. The fundamental idea behind this project has been that, through continuous measurement of wheel profiles, one should be able to take vehicles out of service before any deviating wheel profiles give rise to accelerating wheel and rail wear, and that one should thereby be able to reduce the maintenance costs and increase the operational life of both wheels and rails. An additional result of the project has been increased safety on the track, since it is possible to measure wheels that have exceeded the safety limit for wheel parameters and remove them, which was impossible previously. The following conclusions can be drawn from this project.• There are benefits to be derived from development projects conducted jointly between industry, infrastructure managers and academia. • In order to ensure good results, it is important to perform all the steps in a project, from the concept phase to the handing-over phase. In support of this, the V-model was used, which represents the life cycle of the system according to EN 50126. • The selection of a technical solution and a supplier was made on the basis of the technology level, reference installations, and operation and support possibilities, and not merely based on the price. A development project of this nature is not primarily a question of putting equipment into operation, but of transferring knowhow concerning the possibilities and limitations associated with the technology in question. • The resource requirement for testing and evaluation was underestimated, which resulted in the project being delayed by one year compared with the original timetable. • The information generated by the equipment installed is very useful for all parties working with the development of railway maintenance. • The challenge with regard to utilising the benefits afforded by the measurement station at Sunderby lies in the ability to process the generated condition data for the maintenance organisations concerned and integrate these data in the operations of these organisations.

    Abstract [en]

    Today's providers of maintenance and in-service support related to modern aircraft are facing major challenges. A central problem with maintenance and support of aircraft and other complex technical systems is to manage the ever-increasing information flow and system complexity. Both military and commercial operators need to reduce downtime and one way to do this is to speed up the turnaround time for scheduled and unscheduled maintenance, or even better, to reduce the need thereof by implementing condition based maintenance. In order to implement these improved support solutions in a global support environment, eMaintenance is seen as one important building block. eMaintenance includes monitoring, collection, recording and distribution of real-time system health data, maintenance generated data as well as other decision and performance support to all stakeholders independent of organization or geographical location, 24 hours a day, 7 days a week (24/7). eMaintenance has the potential to improve the management and performance of activities related to the maintenance process, and thereby improve the dependability, safety and life cycle cost of critical systems. This is realized through the application of Information & Communication Technology (ICT) throughout the maintenance and support processes, thus integrating built-in tests, external tests at different maintenance echelons, technical information, diagnostics, prognostics and other sources of support information. The purpose of this paper is to present some results from a joint academic and aerospace industry research project, describing requirements and expectations that are important in a global support environment, and also to propose some central components in an eMaintenance framework that integrates maintenance and ICT perspectives.

    Abstract [en]

    Maintenance and support providers to modern aircraft need to manage an increasing amount of information generated by growing system complexity and stakeholder requirements. This introduces new risks in the information management process and makes traditional information services and systems inadequate. However, recent advancements in information and communication technology (ICT) have contributed to the emerging approach of e-Maintenance, which forms an important building block to achieve the desired information logistics. e-Maintenance enables remote and real time maintenance, and includes; collection, monitoring, analysis and distribution of data and information as decision-support to stakeholders of the maintenance and support processes, independent of organization or geographical location, 24 hours a day and 7 days a week (24/7). This paper describes a proposed development of information products by linking theories to practical methodologies and tools (e.g., Quality Function Deployment, QFD) through the development of a demonstrator of a stakeholder-based information product in the context of a modern combat aircraft.

    Abstract [en]

    Today‟s providers of maintenance and in-service support related to modern aircraft are facing major challenges. A central problem with Maintenance, Repair and Overhaul (MRO) as well as support of aircraft and other complex technical systems, is to manage the ever-increasing information flow and system complexity. Both military and commercial operators need to reduce aircraft downtime and maintenance man hours. Increased manual information management has the opposite effect, inducing unnecessary cost and affect efficiency negatively. Organisations developing and providing maintenance support products and in-service support does also need to improve the capability to efficiently exploit the increasing amount of digital product information and design data provided together with hardware (HW) and software (SW) products from aircraft manufacturers, sub-system suppliers and Original Equipment Manufacturers (OEM). One way to increase aircraft availability and improve maintenance and support efficiency, is to speed up the turnaround time for scheduled and unscheduled maintenance. The ultimate goal is risk-based utilisation and support, where true Condition-Based Maintenance (CBM) is integrated with current operational requirements and available resources in real-time. This aims at the elimination of all preventive scheduled maintenance based on fixed time intervals and execution of only corrective maintenance that has been predicted and turned into scheduled maintenance facilitated by proper support. To address the challenge of information logistics of digital product data and information within maintenance in-service support, providers need to adapt new methodologies and tools that enable full utilisation of the advantages of digital product data and information in processes and business models, e.g. Service-Oriented Architecture (SOA). In order to implement such improved support solutions in a global support environment, eMaintenance is seen as one important building block. eMaintenance includes monitoring, collection, recording and distribution of real-time system health data, maintenance generated data as well as other decision and performance support information to different stakeholders independent of organization or geographical location, 24 hours a day, 7 days a week (24/7). eMaintenance has the potential to improve the management and performance of activities related to the whole maintenance process, and thereby improve the dependability, safety and Life Cycle Cost (LCC) of critical systems. This can be realized through a coordinated application of Information & Communication Technology (ICT) throughout the maintenance and support processes, thus integrating Built-in Test (BIT) systems, external tests at different maintenance echelons, technical information, diagnostics, prognostics and other sources of support information. The purpose of this paper is to present some results from a joint academic and aerospace industry research project, describing requirements and expectations that are important in a global support environment, and also to propose some central components in an eMaintenance framework that integrates maintenance and ICT perspectives.

    iMaintenance stands for integrated, intelligent and immediate maintenance. It integrates various maintenance functions and connects these to all devices, using advanced communication technologies. The main challenge is to integrate the disparate systems and capabilities developed under current eMaintenance models and to make them immediately accessible through intelligent computing technologies. iMaintenance systems are computer-based, able to evolve with the system that they monitor and control, and they can be embedded in the system’s components, providing the ability to integrate new functionality with no downtime. This article will show how iMaintenance systems can provide decision-making support, thereby going beyond merely connecting various maintenance systems.

    Implementation of eMaintenance concept within the Swedish railway2014Konferensbidrag (Refereegranskat)
    Abstract [en]

    An available, reliable and well-maintained railway is the foundation for competition and market growth. Demands on high standardsfor reliable rail transport, tight turnaround times and high utilization of resources (machines, workshops , staff) makes minimumdisturbance in the system to quickly disrupt the entire process of lost capacity, delays and reduced quality to customers as a result.The Swedish railway composed after deregulation, of several different parties, each one with individually objectives and strategy tomaintain their assets and rolling stock. Although some data are railway system common no greater sharing of operation andmaintenance data exists, which creates the risk of sub-optimisation.Luleå Railway Research Center (JVTC) has since 2005 determinedly conducted research in eMaintenance with the aim of usingdifferent types of condition data to develop decision support using preventive measures to prevent disruption of the railway systemin a cost effective manner. eMaintenance aims to perform and control the maintenance with help of condition data and isinterdisciplinary field based on the information and communication technology ( ICT) to ensure that maintenance is carried out inline with both the customer and the supplier's business goals and intrinsic components in all parts of a system's life cycle.eMaintenance concept has developed progressively over the years and now it is acdcepted o be implemented as a pilot project calledePilot119 in the north part of Sweden on track section 119 between Luleå and Boden. ePilot119 delivers a collaboration platform forthe development needs and requirements from various stakeholders to find solutions that enable and transform the Swedishfragmented rail industry to and an integrated system. ePilot 119 will demonstrate the advantages of working with informationtechnology and data in real time to control railway traffic and service. The approach is based on enhanced collaborationmethodology with a framework project and a central team that is unifying for finding smaller sub-projects for transform ePilot119 toa common natural process for sharing maintenance decision support for the railway. The pilot project aims to demonstrate thathigher availability, enhanced capacity and a cost efficient railway operation can be created using the information that is ineMaintenance lab when used in the right way at the. The goal and strategy and the methodology will be to implemented as a naturalapproach to section 119 and then successively implemented in other sections of track in Sweden.

    Governance of digital data sharing in a cross-organisational railway maintenance context2019Ingår i: Proceedings of the 5th International Workshop and Congress on eMaintenance: eMaintenance: Trends in Technologies & methodologies, challenges, possibilites and applications / [ed] Arranz, Miguel Castano, 2019Konferensbidrag (Refereegranskat)
    Abstract [en]

    The purpose of this paper is to study and explore the essential aspects of data governance in eMaintenance that need to be considered such as data sharing and data ownership in a cross-organisational railway maintenance context. Furthermore, the paper develops and provides an approach to strategies and guidelines, which can be used to govern digital data sharing.

    To fulfil this purpose, case studies of several projects where sharing of data between stakeholders in order to develop maintenance decision support, was selected as a research strategy and supported by a literature study. Empirical data were collected through interviews, workshops, document studies, and observations. An approach was developed and validated using a case study.

    The proposed approach supports the understanding and establishing strategies and guidelines for data governance in a cross-organisational railway context. This can be considered as one of the enablers for information logistics for maintenance purposes where the approach can be used as a support tool in order to facilitate the development of maintenance decision support within the railway industry.

    Implementation of eMaintenance concept on the Iron Ore Line in Sweden2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    The Swedish railway is after deregulation composed, of several different stakeholders, each one with individual objectives and strategies to maintain their assets and rolling stock. Although some maintenance data are common between the stakeholders, no greater sharing of these data exists. The insufficient data availability impacts the effectiveness in maintenance decision making.The Luleå Railway Research Center (JVTC) has in more than a decade conducted research in eMaintenance. One of the objectives with eMaintenance research is to develop maintenance decision support tools through enhanced use of information and communication technology for data analytics from various data sources. These tools can also be used to enable condition based maintenance to minimize disruptions and optimise the maintenance cost in a railway system. Another objective this research is to discover how to offer operators, infrastructure managers and system integrators access to central computerised data to support decision making within operation and maintenance.eMaintenance solutions for railway are now being implemented in a pilot project called ePilot119 in the northern part of Sweden on track section 119 between Luleå and Boden. ePilot119 delivers a collaborative platform aimed to enable the development of eMaintenance solutions based on the needs and requirements from various stakeholders. These solutions are expected to enable and transform the Swedish fragmented rail industry to an integrated system, both from an organizational and technical point of view. Some of the objectives are to enhance the sharing of data, developing decision support, define the information and communication technology (ICT) infrastructure and transform ePilot119 to a common natural process for sharing maintenance decision support for the railway.However, implementing eMaintenance solutions to support effective and efficient maintenance decision-making related to a complex technical system (i.e. railway) and with a large number of heterogeneous stakeholders is challenging, and requires appropriate tools (e.g. framework, approaches, methodologies, and technologies).Hence, this paper aims to identify some of the significant factors which need to be considered in order to develop an appropriate implementation process and collaboration platform, which aim to facilitate maintenance decision-making through eMaintenance solutions. By identifying these factors that might hinder the execution of the project and implementation of good results, there is a possibility to jointly create the best prerequisites for the operation and maintenance of the railway system.

    Change management in digitalised operation and maintenance of railway2019Ingår i: PROCEEDINGS: International Heavy Haul Association Conference June 2019, 2019, s. 904-911Konferensbidrag (Refereegranskat)
    Abstract [en]

    Globally, railway is experiencing a major technology transformation (or paradigm shift), triggered by the enhanced utilisation of digital technology. This technological transformation affects not only the technical systems, i.e. railway infrastructure and rolling stock, but also regulations, organisations, processes,and individuals. Hence, hardware, software, but also liveware (i.e. humans) are affected. Today, the digitalisation of railway is characterised by digital services. There are also a range of challenges, e.g. data acquisition,transformation, modelling, processing, visualisation, safety, security, quality, and information assurance. To deal with these challenges, the railway industry needs to define strategies, which enable a smooth transformation of the existing configuration to a digitalised system. Digital railway requires a holistic change management approach based on system-of-systems thinking and a set of appropriate technologies and methodologies. The railway digitalisation strategy should be based on systematic risk management that address aspects of, e.g., information security, traffic safety and project risk. In addition, managing changes for a digitalised railway effectively and efficiently also requires a framework for aspects such as needs finding, requirement identification, and impact of changes for individual, teams and organisation. In this work a major case studywithin the ePilot, has been performed in context of the operation and maintenance processes of the Swedish railway. Therefore, this paper aims to propose a framework for implementing innovations and driving change in a digitalised railway.

    Abstract [en]

    Many intellectual, societal, business and technological forces are continuously pushing forward the frontiers of science. When combined, they provide an umbrella for generating new fields and exploring new grounds. One such a new field is eMaintenance. eMaintenance addresses new needs and provides various benefits in form of increased availability, reduced lifecycle cost and increased customer value. However, it suffers from lack of a commonly defined basis supporting the existence of eMaintenance and determining the essential components inherent in the eMaintenance domain. In this paper, we suggest an initial set of components that serve as the groundwork of the eMaintenance universe. The set outlines ten initial components. These are Definition, Business, Organization, Product, Service, Methodology, Technology, Information, Customer, and Education and Training. The paper also suggests a definition of eMaintenance, places eMaintenance in the context of other eDomains, and elicits eMaintenance intellectual opportunities and challenges to be met by both the academia and industry.

    Fundamentals of the eMaintenance concept2010Ingår i: Proceedings of the 1st international workshop and congress on eMaintenance, Luleå tekniska universitet, 2010, s. 147-154Konferensbidrag (Refereegranskat)
    Abstract [en]

    Many intellectual, societal, business and technological forces are continuously pushing forward the frontiers of science. When being combined effectively, they may provide an umbrella for generating new fields and exploring new grounds. One such emerging field is eMaintenance. It is based on the fields from operation & maintenance engineering, software engineering, information systems, business management, and a myriad of strongly varying fields related to the application domains of eMaintenance. As a novel field, eMaintenance addresses new needs and provides various benefits in form of increased availability, reduced lifecycle cost and increased customer-value. On the other hand, being in a continuous flux, it suffers from many infant illnesses in form of lack of or fuzzy definitions and theoretical foundations. This paper explores the domain of eMaintenance. In striving toward that end, it defines the eMaintenance concept by identifying its essential constituents and characteristics, mapping out its application domains and by eliciting its intellectual opportunities and challenges. Finally, the paper reasons about the future of eMaintenance as an emerging field and identifies research questions that may serve as the impetus for defining future research strategies. Last but not least, it lists challenges to be met by the organizations transferring to eMainteannce and advocates to the eMaintenance community to further elaborate and improve the eMaintenance concept.

    A service-oriented approach to e-maintenance of complex technical systems2008Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    In today's global business scenarios, an organization can strengthen its com-petitiveness by offering a spectrum of industrial services that range from tra-ditional customer support to turnkey solutions. To achieve this service spec-trum, it is necessary to manage information consumption and production at right quality level in right time. When dealing with complex technical systems, e.g. military aircraft, with long life cycles, the management of maintenance-related information is crucial to fulfil stringent dependability, Life Support Cost (LSC) and safety requirements. Today, there is available Information & Communication Technology (ICT) to realize an eMaintenance solution for the necessary information logistics. However, there is a lack of appropriate frameworks, methodologies and tools that enable a service-oriented approach to eMaintenance. Hence, the purpose of this research is to explore and describe how an eMaintenance solution can be developed to provide information services that support the maintenance of complex technical systems. To fulfil the purpose, a major case study within military aviation has been performed, supported by two minor case studies within the healthcare sector and the process industry. Empirical data has been collected through interviews, observations, archival records and workshops. The analysis is based on developed theoretical frameworks, Design of Experiment (DoE) principles and available interna-tional standards. The results of this research are: I) an exploration and definition of eMaintenance; II) a description of eMaintenance as support to maintenance of complex technical systems; III) an eMaintenance Management Framework (eMMF) for establishment of an eMaintenance platform; and IV) a methodology with a supporting toolbox that facilitates the identification of maintenance support information.

    Design pattern for development and maintenance of geographical IT systems2005Licentiatavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    The information society, having a growing information domain/amount, requires a reliable information infrastructure with ability to distribute the right information from the right information producer to the right information consumer, at the right time and with the right quality on demand (information-on-demand). Another growing demand, parallel with the information distribution infrastructure, is information visualization. Information visualization is one of the important tools that help consumers to interpret and understand the distributed data, and facilitate the decision-making process. Maps have always been a popular method for visualizing spatial objects, objects that contain spatial references such as address co-ordinates and building ID. The rapidly growing need for geographical information systems (also called GI systems/applications) and components has an impact on the processes of development and maintenance of geographical information systems and components. The main purpose of this research is to study design patterns and suggest methods, models, rules of thumb and so on to improve the process of development and maintaining geographical information systems and reduce the total life cycle cost. The main objective is divided into following sub objectives, namely, a) to describe different patterns, solutions, models, suggestions and recommendations that can improve the process of developing GI-applications in order to reduce the cost of producing, developing and maintaining applications with a high level of quality and serviceability, b) to examine if and how the idea of design pattern is applicable to the architecture of software with spatial components (commonly called GI systems), c) to identify the factors that impact the costs of GI software development and maintenance processes and if possible recommend a model for reducing the cost and improving the quality of the solutions, d) to find and suggest solutions, models, rules of thumb, suggestions and recommendations that can improve the process of developing GI-applications. During the study, it has been noticed that recurrent GI-problems are solved but those solutions are hardly communicated among developers. On the basis of software developed in many of the research projects and also students' works we have observed that the architecture of GI software is in most cases similar to any other software. This similarity makes it possible to apply general software development patterns to GI applications. Further more it is noticed that recurring problems are not dependent on who the developer is or to what category she or he belongs, but on the problem situation and the context of the application. This means that the developer faces almost the same kinds of problems in a given situation. It has also been noticed that the size of projects and demands from customers, management, development organisations and culture/experiences, maintenance organisations and so on have an effect on how much the developer group need to use patterns and semi-manufactured components during the software development process. The study has shown that generic IT patterns can be used for designing GI-applications, but there is still a need for technology- and product-specific patterns for GI- components

    Project: eMaintenance infrastructure for enhanced information logistics2010Övrigt (Övrig (populärvetenskap, debatt, mm))
    Abstract [en]

    The availability of qualified operational data and information from the operational use of complex aircraft system is becoming increasingly important and more valuable for both operators and suppliers of aircraft system. An example is Airbus, which lets customers offset a significant part of the cost of support received by Airbus if they provide operational and maintenance data. Another example is Saab's availability contract for SK60, where a faster feedback of operational and maintenance data in (near) real time is critical for control of  flight production and contract monitoring. Traditional Operational Performance Monitoring (OPM), with a focus on monitoring of airworthiness, and system evaluations for Life Cycle Management (LCM) are often done, e.g. annually. Increased demands on aircraft system and maintenance providers to improve availability and dependability through availability-focused maintenance, reducing Life Cycle Cost (LCC) and Life Support Cost (LSC) and the introduction of performance-based business models (Performance-Based Logistics, PBL and Contracted Logistic Support, CLS) introduces new and more stringent demands on OPM and LCM. Access to relevant operational and maintenance data, and the use of OPM and LCM as analytical tools and control instruments are becoming increasingly important to manage the technical and commercial risks inherent in changing maintenance solutions (eg, dynamic maintenance plans) and new business models. At the same time, the quality of data, existing Information & Communication Technology (ICT), tools, manual intervention and outdated information security and privacy solutions are often a limitation for the development of OPM, LCM and other qualified support services, which are necessary to streamline operation and maintenance and to support PBL and CLS.The project aims to improve the infrastructure for data and information exchange between operators and suppliers to identify, adapt and integrate ICT-based methods and solutions for a so-called eMaintenance-infrastructure, enabling improved efficiency and further development of primary OPM and LCM in support of PBL/CLS, dynamic maintenance schedules and new information-based decision-support services for operation, maintenance and support.

    Cloud-based emaintenance solutions for condition-based maintenance of wheels in heavy haul operation2015Ingår i: 11th International Heavy Haul Conference, (IHHA 2015): 21 – 24 June 2015, Perth, Australia, International Heavy Haul Association , 2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    The Swedish ore line, began in 1898 and was completed and operational by 1902. The line was later electrified and remains so to this day. A study on wheel-rail interaction, to optimize wheel and rail profiles on the Malmbanan and Ofoten lines states that there is a need to develop and apply limit values for the allowable length of single and multiple cracks on wheels. Herein, all stakeholders in the railway organization have to be involved. Provisioning of an integrated decision support system for track and vehicle contributes to increased efficiency and improved effectiveness of the maintenance process, which in turn enables achievement of business excellence. However, an integrated decision support process for maintenance is highly dependent on appropriate information logistics which enables information provisioning to various maintenance stakeholders. One emerging approach for development of eMaintenance solutions is utilization of cloud-based technologies. Cloud-based eMaintenance solutions promises smooth information logistics for maintenance decision support. Hence, the purpose of this paper is to propose an approach for condition-based maintenance decision-making relating to railway vehicle wheels, based on a cloud-based eMaintenance solution. The paper also demonstrates how the proposed approach can be implemented for estimation of Remaining Useful Life (RUL) of railway vehicle wheels.

    Development of ICT-based maintenance support services2009Ingår i: Journal of Quality in Maintenance Engineering, ISSN 1355-2511, E-ISSN 1758-7832, Vol. 15, nr 2, s. 127-150Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose - The purpose of this paper is to describe a taxonomy for an eMaintenance management framework (eMMF) based on a service-oriented approach, in order to facilitate the development of information and communication technology (ICT)-based maintenance support services aimed at actors within the maintenance process related to complex technical industrial systems. Design/methodology/approach - To fulfil this purpose, a case study of a modern multi-role combat aircraft is selected as an appropriate research strategy and supported by a literature study. Empirical data are collected through interviews, workshops, document studies, and observations. A framework is developed and evaluated using a prototype within the studied case. The study is performed in close cooperation with the aircraft's type certificate holder and the customer representative and operator in one country. Findings - The proposed eMMF aids in the identification and development of ICT-based maintenance support services tailored for specific maintenance actors and their activities. Research limitations/implications - To further test the usefulness of the proposed framework, a larger scale application must be performed. This can involve additional stakeholders or a larger part of the technical system in the selected case, or another case dealing with complex technical industrial systems. Practical implications - The proposed framework supports the identification of required information services that support the maintenance process, which in turn supports the development of a service-oriented architecture (SOA) aimed at proper maintenance information logistics. Hence, people working with information logistics for maintenance purposes can use the framework as a support tool. Originality/value - The proposed framework combines a process and service-oriented approach, which facilitates the development of SOA-based information services by giving valuable input to more traditional system-oriented approaches

The analysis was founded on theories related to maintenance and maintenance support. The conclusions of the study are corroborated by experiences from earlier software development and testing. FindingsMost existing contributions to the eMaintenance debate seem to suffer from too wide a gap between data processing and knowledge management. This tendency can be due to too great a focus on data collection, without any clear identification of the stakeholders‟ requirements. Hence, a mature eMaintenance solution should focus on the enhancement of service-oriented information logistics based on content sharing for an output-based information strategy.

    Robust and Reliable Transport System: A strategic agenda for resource pooling, collaboration, innovation and research2015Rapport (Övrig (populärvetenskap, debatt, mm))
    Abstract [sv]

    Sverige och omvärlden står inför stora utmaningar med ett ständigt ökande transportbehov där dagens och framtidens hållbarhets- och klimatkrav ska uppfyllas. Med stora avstånd och relativt liten befolkning har Sverige en unik uppsättning transportbehov, och med en åldrande infrastruktur skärps utmaningarna ytterligare. Agendan vill staka ut den strategiska vägen för framtidens väg- och järnvägstransporter.Visionen är att möjliggöra ett robust, motståndskraftigt och pålitligt transportsystem som samtidigt är attraktivt, säkert hållbart och effektivt. Denna vision ska realiseras genom tre huvudsakliga delmål

    • förbättrad ekonomisk, samhällelig och miljömässig effektivitet
    • reducerade störningar – de närmaste fem åren ska två tredjedelar av de störningar som påverkar transportkvalitet och klimat vara borta
    • utökad samverkan och samarbete mellan industri, politik och akademi ska skapa en systemsyn med kvalitet i transporter som mål.

    För att målbilden ska bli verklighet behöver insatser bedrivas inom fyra fokusområden

    • styrning av transportsystemet
    • innovation i transportsystemet
    • godstransporter och passagerartrafik
    • intelligent transportsystem.

    Inom fokusområdena ska särskild vikt läggas på ett antal kärnaktiviteter, bland annat:

    • nätverkande mellan olika aktörer och organisationer
    • idéfora för innovationsprojekt
    • forskning
    • noder av testmiljöer
    • uppstartsstöd
    • tillväxtsstöd för små och medelstora företag.

    Agendans insatsområden ska mötas genom nära samverkan mellan aktörerna i ett incitamentdrivet trippelhelix med ett holistiskt systemperspektiv. Aktörerna i samverkan omfattar infrastrukturförvaltare, trafikutövare, akademi och institut, design- och projekteringskonsulter, systemleverantörer, entreprenadföretag och underhållsföretag.

    Service-oriented information logistics as support to asset management of complex technical systems2009Konferensbidrag (Refereegranskat)
    Abstract [en]

    The global business scenario under the economic slowdown demands an increased environmental sustainability of asset during its whole life cycle, besides the other requirements like, Life Support Cost (LSC) and availability performance. To fulfill these requirements, a need exist for introducing asset management philosophy with integrated management strategy. Further, an effective asset management is also dependent on other prerequisites such as a proper support infrastructure, which include human resources, support equipment, materials and spare parts, facilities, documentation, information and information systems. Information is essential in order to facilitate asset management and enable the achievement of overall business objectives. Hence, asset related information need to be provided through a proper information logistics.Information logistics aims to provide just-in-time information to the actors of asset management and to optimize the information supply process, i.e. making the right information available at the right time and at the right point of location. In this context the delivery of accurate and timely information to the information consumer and its adaption to the right situation is highly important.Information logistics for an extensive information context related to complex technical systems with capability such as mobility, real-time delivery, context-awareness and situation-awareness requires appropriate methodologies and technologies. These methodologies and technologies are aimed to be utilized to provide an efficient ICT infrastructure, context-dependent extraction of complex data and information and also to facilitate autonomous decision-making and control. Furthermore, since asset management is a process that should consider all phases of a systems whole lifecycle, e.g. conceptual design; preliminary system design; detailed system design and development; production and construction; utilisation and support; and retirement and disposal; its related information logistics also needs to provide capability to manage information from all inherent phases of the system lifecycle. However, establishment of appropriate information logistics including mechanism for time management, which addresses 'when to deliver'; content management, which refers to 'what to deliver'; communication management, which refers to 'how to deliver'; and context management, which addresses 'where and why to deliver' throughout all phases of a system lifecycle is a great challenge, since necessary information is often hidden among vast quantities of data, stored for other purposes, in different places, and in different formats, and generated throughout the entire lifecycle of a system. Hence, it is commonly realized that the establishment of a dynamic and effective solution for information logistics requires appropriate software architecture and related infrastructure. However, the ultimate goal of information logistics in this context is to support the asset management process to achieve the overall business objectives through provision of information to its stakeholders. This paper describes a service-oriented approach to establishment of information logistics related to asset management of complex technical system within the context of military aviation.

    eMaintenance industrial applications: issues and challenges2014Ingår i: Engineering Asset Management 2011: Proceedings of the Sixth World Congress on Engineering Asset Management / [ed] Jay Lee; Jun Ni; Jagnathan Sarangapani; Joseph Mathew, New York: Encyclopedia of Global Archaeology/Springer Verlag, 2014, s. 33-40Konferensbidrag (Refereegranskat)
    Abstract [en]

    Achieving business excellence within industries which utilise complex technical systems requires effective and efficient maintenance. Maintenance is an important enabler of business performance. An effective maintenance strategy creates additional values in an organisation’s value-generating process. Establishing an effective and efficient maintenance process is highly dependent on supporting Information and Communication Technology (ICT) infrastructure for information logistics that facilitates maintenance decision support. eMaintenance solutions facilitates effective and efficient management and control of maintenance activities through an enhanced utilisation of computing; like;.estimation of their Remaining Useful Life (RUL); reduction of No-Fault Found (NFF); and prediction of fault. eMaintenance solutions enable a seamless integration and fusion of information services provided by information intensive systems with embedded components in order to manage increasing and extentensively distributed real‐time data collected via different data sources (e. g. sensors). Since, the emerging ‘Internet of Things’ is expecting to dramatically change information systems with inherent embedded components, eMaintenance solutions need to be adapted to this new context to fulfil the overall business requirements on an effective and efficient decision-making process; for e.g.: real‐time analysis based on real‐time data and context-aware information logistics. However, development and establishment of proper eMaintenance solutions can be facilitated through utilisation of appropriate framework which deals with real-world challenges. This paper explores some of the issues and challenges pertaining to eMaintenance industrial application.

    An enterprise risk management framework for evaluation of eMaintenance2010Ingår i: International Journal of Systems Assurance Engineering and Management, Vol. 1, nr 3, s. 219-228Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Maintenance is one approach to managing risk by a reduction of the probability of failure of technical systems and/or the consequences of their failure. However, history has shown that erroneous maintenance also can lead to reduced quality, incidents and accidents with extensive losses. Today, eMaintenance promises great opportunities for a paradigm shift from a rather narrow, condition-based maintenance approach with focus on a technical system’s health to a true risk-based maintenance approach that also considers organizational excellence. This is achieved by proper information logistic solutions that address the needs of all stakeholders of the maintenance process, which are possible due to new and innovative information and com- munication technology (ICT). However, all opportunities are also linked with some threats, which are seldom high- lighted in the case of eMaintenance. In this article, a risk management framework for evaluation of eMaintenance solutions is proposed. The framework is based on a combi- nation of international standards (e.g. ISO 31000, ISO/IEC 27000, and IEC (2004) 60300-3-14) to achieve integrated Enterprise Risk Management (ERM) and enable a linkage of eMaintenance to the strategic goals of an organization. Theframework is illustrated in the railway context of Trafik- 30verket (2010b) (the Swedish Transport Administration).
