Software product line engineering deals with the combined development of a family of similar software systems. These systems provide a similar set of features and should therefore share a large number of common components. We study the user perspective of features and the engineering perspective of components and present a formal notion of features, component-based product families and their in...

Holistic methods covering the development process as a whole – e.g. systems engineering – have established themselves in product design. However, technical product optimization, representing improvements in efficiency and/or minimization of loss, usually applies to single components of a system. A holistic approach is being defined based on a hierarchical point of view of systems engineering. T...

ion level, due to the findings that requirements can relate to existing products. At this level, feasible methods to identify requirements are interviews and focus groups. The questions like those suggested by Ulrich and Eppinger [5] are useful to get insights into people’s preferences for improvements on existing products.

We study properties of structured financial products optimizing a utility functional of a customer. The conventional method may have the disadvantage that the a priori restriction to a certain number of assets could make it impossible to find the optimal portfolio. So instead of optimizing the distribution of given assets, we impose only the price constraint as given by the CAPM and optimize th...

When people interact with products, all sensory modalities are open to receive information. To assess each modality's potential contribution to overall product experiences, we developed a split-modality approach, in which subjects experienced real-life products through only one modality: vision, touch, audition, or olfaction. Responses focused on (1) description of the sensory experience, (2) p...

The relationship between different types of innovation is analysed from three different approaches. On the one hand, the distinctive view assumes that the determinants of each type of innovation are different and therefore there is no relationship between them. On the other hand, the integrative view considers that the different types of innovation are complementary. Finally, the product-proces...

In recent years, growing ecological concern has prompted for ‘design for environment’. One way to achieve this is to design products that are easy to disassemble, because this improves the ability to reuse or recycle parts of a product. This paper presents a computational theory for product modeling and reasoning about product disassembly. This theory, implemented in the PROMOD system, is based...
