Knowledge Base Repository
In addition to research papers, the Design Society is developing several valuable resources for those interested in the study of design. These include a repository of PhD theses, a library of case studies and transcripts of design activities, and an archive of our newsletters. Please note that these resources are accessible exclusively to Design Society members.

Abstract:
The most important stage in a product life cycle is the conceptual design which involves uncertainty but also opportunity. The SOS method of generating product design alternatives [1] is expanded here to introduce more information to help reduce uncertainty and explore design solutions to better suite customer requirements, market conditions, and the use of current technology. Hierarchical SOS uses two levels of building blocks: the 1st level contains major building blocks (the same as in regular SOS) and the 2nd level contains slightly more detailed articulations of the building blocks of the 1st level. The product requirements are cascaded to the 2nd level and are translated to secondary targets. The search of the best product design alternatives is done by a genetic algorithm (GA). As expected, the new information introduced and manipulated at the 2nd level turns out to be critical for creating good conceptual designs.
