Abstract [en]

In order to make the designing of product variants more efficient and effective there often exists the possibility of automating the process, or at least implementing some form of computer support to aid the designers. Designing though, is often not a simple and single task. Instead, it often consists of several interlinked sub-tasks that have to be performed either in some previously known order, iteratively, or perhaps even by inference. Furthermore, the levels of knowledge and task formalisation and process maturity may vary from known and clearly documented tasks (explicit), to known but undocumented tasks (implicit), or even unclear and unstructured tasks (ad-hoc).

In doing so a clearer picture of the actual design process will emerge and a problem definition and/or system specification can be outlined [Cederfeldt 2005]. This will in turn give rise to new questions that needs to be answered in parallel with setting up of a final system specification. Some of these questions address the choice of solution approach related to the design process and its inherent knowledge. This paper presents one such attempt at breaking down a design problem, defining its process character and capturing its inherent domain knowledge. This is then mapped to suitable tools, and computer implementations. One of the tools chosen in this work, Cased Based Reasoning (CBR), will be addressed further and some implementation issues of CBR as well as the advantages of a variant design approach to setting up of CBR indexing templates are discussed in more detail.
