- Individualized products, resource-smart design and production, and afocus on customer value have been pointed out as three opportunities for Swedishindustry to stay competitive on a globalized market. All these three opportunitiescan be gained by efficient design and manufacture of highly customized products.However, this requires the development and integration of the knowledge-basedenabling technologies of the future as pointed out by The European Factories ofthe Future Research Association (EFFRA). Highly custom engineered productsrequire an exercising of a very rich and diverse knowledge base about the products,their production and the required resources for design and manufacture. Thedevelopment and implementation of systems for automated design and productionpreparation of customized products is a significant investment in time and money.However, our experience from industry indicates that significant efforts arerequired to introduce and align these kinds of systems with existing operations,legacy systems and overall state of practice. In this paper, support for systemdevelopment in literature has been reviewed in combination with a survey on thestate of practice in four companies regarding implementation and management ofautomated systems for custom engineered products. A gap has been identified anda set of areas for further research are outlined.

Support Maintenance of Design Automation Systems - A Framework to Capture, Structure and Access Design Rationale
- 2015

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The ability to innovate and launch customized products that are well matched to customer demands is a competitive factor for many manufacturing companies. Development of highly customized products requires following an engineer-to-order business process to allow the products to be modified or adapted to new customers’ specifications, which brings more value to the customer and profit to the company.Design of a new product variant involves a large amount of repetitive and time consuming tasks but also information handling activities that are sometimes beyond human capabilities. Such work that does not rely so much on creativity can be carried out more efficiently by applying design automation systems. Design automation stands out as an effective means of cutting costs and lead time for a range of well-defined design activities and is mainly considered as a computer-based tool that processes and manipulates the design information.Adaptation and variant design usually concern generating a new variant of a basic design, which has been developed and proved previously, according to new customer’s demands. In order to efficiently generate a new variant, a deep understanding of the previous design is essential. Such understanding can be achieved by access to the design rationale explaining the reasons and justifications behind the design.Maintenance of design automation systems is essential to retain their usefulness over time and adapt them to new circumstances. New circumstances are, for example, introduction of new variants of existing products, changes in design rules in order to meet new standards or legislations, or changes in technology. To maintain a design automation system, updating the design knowledge (e.g. design rules) is required. Use of design rationale will normally become a necessity to allow a better understanding of the knowledge. Consequently, there is a need of principles and methods to enable capture, structure, and access design rationale.In this study, a framework for modeling design knowledge and managing design rationale in order to support maintenance of design automation systems is presented. Managing of design rationale concerns enabling capture, structure, and access to design rationale. In order to evaluate the applicability of the framework, the findings are tested through design automation systems in two case companies.

Tidskriftsartikel (refereegranskat)abstract
- In this paper interviews with staff involved in product development from four different companies is presented. The objective is to find out how the companies manage the technical risk of introducing new technology in products and how they prepare for meeting changing requirements from customers. The companies originates from aerospace, automotive and production engineering. Based on the results of the first study, a case study was carried out at the aerospace company. The studies shows that, the introduction of new technology varies with the risk of failure in the validation of the products. Companies that easily can revert back to the former technology is more risk taking. The types of products and the companies’ place in the supply chain has an impact on technology introduction and requirements handling. The companies have strategies for developing requirement specifications prior to the start of the project. This is most elaborate at the aerospace company where a thorough concept evaluation clarify possible variations in requirements.
