Abstract [en]

This paper features the implementation and evaluation of a proposed approach for information capture and representation integrated into the existing design environments at two manufacturing companies. A tool has been developed that automatically derives information from the CAD system during design and provides users with the means to capture product information that has previously been documented outside of the CAD system. Product information is managed in a PLM data model and becomes, once stored, the foundation for providing tailored views of information.Feedback from the evaluation shows that the prescribed approach was preferred to the current one and that it would likely provide value to users, both authors and consumers, of product information. This approach can reduce the time required to capture the pertinent product information. However, the primary savings are likely to be indirect as a result of increased consistency, understanding, and the potential (re)use of product information.The approach and tools presented constitute another step toward providing each stakeholder with more efficient, intuitive, contextual, and purposeful support for information capture and representation in computer-aided product development.

Abstract [en]

Providing not only products but a combination of products and services can help add value and enable competitiveness for both the providers and their customers. Research has suggested Functional Products (FP) as one concept to achieving this combination of products and services.Traditionally, when a product is sold the ownership of the product is transferred to the customer, making it difficult for the provider to access information from the products use phase. In the case of FP, the ownership of the product is retained by the provider, and access to use phase information is essential to provide the function at a guaranteed level of availability. This information access also allows feedback to earlier life cycle phases. This paper explores how information generated in the use phase of FP can be integrated with the virtual product representation in a Product Lifecycle Management (PLM) system.A concept was developed for capturing use phase information from a potential FP. The concept utilizes wireless sensors that makes the information available through networks. WebSockets are used for providing real-time access and visualisation of the information. Both real-time and historical information can be accessed in a dashboard by any device that supports HTML5. A PLM system connects relevant information from the FP in use with the virtual representation of the FP.The concept was implemented in a case at a producer of automotive parts. A unified solution for information management of both use and development of FP was achieved by integrating use phase information and the virtual product representation

Abstract [en]

Information management during product development and over the lifecycle of products has become central to enable competitiveness in the engineering industry. Reuse and integration of information is essential to avoid duplicating efforts. This need for methods and tools which effectively enable capture, retrieval, representation, and reuse of information.The research presented in this thesis is based on investigations of information management at two companies in the engineering industry in Sweden. One case at each company was identified. The cases focused on the methods and tools with which product-related information is captured, retrieved represented, and reused.The challenge lies in ensuring that pertinent product information can be efficiently captured and, once stored, can be understood, used, and reused by both systems and individuals.To address the challenge, an approach for integrating information in Product Development was developed, implemented, and evaluated. One of the bases of the approach is the information architecture used to provide easy access to product information in an integrated and customizable way. Information is stored in a main source, a Product Lifecycle Management (PLM) system tightly integrated with other sources. These tightly integrated information sources together form a PLM solution. The data model of the PLM system becomes the unified data model for the product information. The approach allows for redundancy-free storage that ensures that the information provided is up-to-date and valid. Ease of access to the information is provided by utilizing a service-oriented architecture to provide Web applications and integrations.Close collaboration between researchers and users has been essential throughout the entire process of investigation, implementation, and evaluation.Feedback from the evaluation showed that the prescribed approach was preferred to the old approach and that the participants from both companies agree that it will likely provide value to both authors and consumers of the information.

Abstract [en]

The amount of product and process related information in the engineering industry is large and constantly growing. Methods and tools are therefore needed to effectively leverage the information, ensuring that it is readily available, contextually understandable and usable for the activity at hand. This paper presents findings from two cases performed at manufacturing companies and an approach for how information effectively can be utilized during the development and lifecycle of a product. The approach primarily addresses the lack of up-to-date information, free of redundancies and accessible from the context where it is needed or will be captured.
