Abstract [en]

n a case study comprising two SMEs offering Industrial Product-Service Systems (IPS2) based on the industrial internet the paper addresses the current cybersecurity level of the two SMEs and the perceived need for added cybersecurity features. Cybersecurity is of crucial importance for most IPS2-offerings if they involve data communications, data collection and storage, and are also part of the customers’ critical processes (i.e., the core processes that always need to work with a high level of availability). The case study reveals that both IPS2-offerings have a basic level of core security spanning IoT-devices, IoT-networks, cloud services and users as well as administrators. Further, of interest is that the SMEs would like to add security cloud services with advanced security functionality in order to achieve scalability and efficiency regarding security- and general management as well as lifecycle management functionality. However, most of the security cloud services are mainly aimed at larger companies and not adapted for SMEs in terms of required knowledge, time and effort required to keep the security configurations up-to-date.

Abstract [en]

The paper addresses machine learning methods, utilizing data from industrial control systems, that are suitable for detecting anomalies in the press-hardening process of automotive components. The paper is based on a survey of methods for anomaly detection in various applications. Suitable methods for the press-hardening process are implemented and evaluated. The result shows that it is possible to implement machine learning for anomaly detection by non-machine learning experts utilizing readily available programming libraries/APIs. The three evaluated methods for anomaly detection in the press-hardening process all perform well, with the autoencoder neural network scoring highest in the evaluation.

Abstract [en]

In order to reduce unnecessary stops and expensive downtime originating from clutch failure of construction equipment machines; adequate real time sensor data measured on the machinein combination with feature extraction and classification methods may be utilized.

This paper, based on a study at Volvo Construction Equipment,presents a framework with feature extraction methods and an anomaly detection module combined with Case-Based Reasoning (CBR) for on-board clutch slippage detection and diagnosis in a heavy duty equipment. The feature extraction methods used are Moving Average Square Value Filtering (MASVF) and a measure of the fourth order statistical properties of the signals implemented as continuous queries over data streams. The anomaly detection module has two components,the Gaussian Mixture Model (GMM) and the Logistics Regression classifier. CBR is a learning approach that classifies faults by creating a new solution for a new fault case from the solution of the previous fault cases. Through use of a data stream management system and continuous queries (CQs), the anomaly detection module continuously waits for a clutch slippage event detected by the feature extraction methods, the query returns a set of features which activates the anomaly detection module. The first component of the anomaly detection module trains a GMM to extracted features while the second component uses a Logistic Regression classifier for classifying normal and anomalous data. When an anomalyis detected, the Case-Based diagnosis module is activated for fault severity estimation.

Abstract [en]

Wearable computing is gaining more and more interest as new "wearables," intended for both work and leisure, are introduced. This trend brings benefits and challenges; for instance, the potential to improve work processes and issues related to IT management and privacy. The introduction and use of wearable computing provides opportunities to improve and reengineer work processes in organizations but can at the same time introduce alignment problems, as users in organizations may adopt the new technology before organizations are prepared. Further, alignment problems posed by the emerging trend, "Bring Your Own Device" (BYOD), are discussed. In addition, as in the cloud computing area, needed and necessary supportive legal frameworks have not yet fully addressed the new wearable computing technology. In the light of recent developments regarding global intelligence gathering, security and privacy concerns must be given careful consideration. Different alignment concepts for managing security challenges and legal aspects related to wearable computing, such as cultivation, care, hospitality, and care with hospitality, are discussed in the chapter. © 2018 by IGI Global.

Abstract [en]

Enabling value co-creation between provider and customer is a key requirement for successful adoption of integrated product-service offerings in a capital good industrial setting. However, little is known about the barriers and conditions explaining customers willingness to open up their internal processes for value co-creation with providers. Based on a multiple exploratory case studies with four customers and four providers within the manufacturing and process industries, this study identifies three barriers to open operation (operational cultural resistance, loss of operational know-how and risk of operational conflict) which may restrict the potential for increased value co-creation and must be managed to support the adoption of integrated solutions. In addition, we identify two key conditions related to the criticality of the operational process and the state of operational competences as strong influences for which form of open operation engagement would be favoured by customer. The study holds both theoretical and practical implications.

Abstract [en]

The book chapter addresses which measures five manufacturing companies have taken, or plan to take, regarding use of data originating from monitoring, service, support, maintenance, repairs as well as other sources, in order to improve the knowledge on availability in the context of providing Functional Products. Commonly, the objective of Functional Products is to provide a function to customers with a specified level of availability (or improvement of productivity or efficiency). The results indicate that systematic planning and collection of relevant data, which is either pre-processed on-board (i.e., locally) or sent as is to central or cloud-based storage and processing, in combination with additional necessary data from other sources, is crucial to build knowledge in order to uphold and improve the level of availability agreed upon with customers. As the use of software in Functional Products increases, the knowledge on availability related to software must be augmented—which can be a challenge for many companies whose operations have been rooted in hardware. Further, the results reveal that getting high-quality input is key in order to use the collected data for analytics and to find root causes. The latter may change how the current value-chain operates and secures the quality of necessary data when providing functions to customers if partners are involved in the provider consortium.

Abstract [en]

In order to reduce costly downtime, adequate condition monitoring of the automatic transmission components in heavy duty construction equipment is necessary. The transmission in such equipment enables to change the gear ratio automatically. Further, the bearings in an automatic transmission provide low friction support to its rotating parts and act as an interface separating stationary from rotating components. Wear or other bearing faults may lead to an increase in energy consumption as well as failure of other related components in the automatic transmission, and thus costly downtime. In this study, different sensor data (particularly vibration) was collected on the automatic transmission during controlled test cycles in an automatic transmission test rig to enable adequate condition monitoring.

An analysis of the measured vibration data was carried out using signal processing methods. The results indicate that predictive maintenance information related to the automatic transmission bearings may be extracted from vibrations measured on an automatic transmission. This information may be used for early fault detection, thus improving uptime and availability of heavy duty construction equipment.

Abstract [en]

The paper, based on an empirical study involving five companies, concerns software-related measures that are planned and taken by providers together with their customers to improve the availability of Functional Products (FP) or similar offers. The manufacturing industry is showing an increasing interest in adding offerings based on additionally complex business models, as opposed to merely offering products and services. This supports innovation and helps companies to stay competitive and profitable. Considerable focus is placed on performance- or result-based business models. Functional Products (FP) is one such business model, where the provider offers a function to customers at an agreed-upon level of availability, productivity or efficiency. FP comprise four main constituents: hardware, software, service-support system and management of operation, which together deliver value to customers on a long-term basis. The paper highlights nine software-related availability measures planned and taken by manufacturing companies and proposes additional potential software-related availability measures.

Abstract [en]

The paper concerns a case study about optimizing recycling management in terms of emptying containers holding, for instance, glass, paper, plastics or metal waste collected, thus supporting sustainability of natural resources and the circular economy. The case has been followed from the very start all the way to the current transformation into an IPS2 sold on a subscription basis. The main results of the case study suggest that the provider side must change considerably in terms of the business and organizational set-up, which has been challenging compared to the necessary, though more easily implemented, technological changes. Further, the IPS2 customers foresee improved efficiency and a decrease in unnecessary work if containers are emptied on time. In addition, the core of the IPS2 seems generalizable and transferable to other applications where collection and analysis of data are needed to support decision-making.

Abstract [en]

Currently, industry is showing increasing interest in performance-based business models. Functional Products is one such business model, where the provider offers a function to customers at an agreed-upon level of availability, productivity or efficiency, etc. A Functional Product comprises the following four main constituents: hardware, software, service support system and management of operation, which together deliver value to customers on a long-term basis. This paper, based on empirical data, provides an outline and starts the verification of a proposed overall Functional Product lifecycle combining and coordinating its economic- and technical perspectives. The perspectives are combined and the key aspects of the necessary coordination between and within the perspectives, i.e., sustainable win-win situations and coordination of sub-lifecycles for the economic perspective, and the need for coordination between the Functional Products’ technical perspective's four sub-lifecycles (hardware, software, service-support system and management of operation), are elaborated and discussed. Further, addition of new functionality, contract management, and long-term management of operation are discussed in the light of managing fleets/individual customers, assets and availability. The proposed overall Functional Product lifecycle is further analyzed from a number of views and aspects.
