The aim of this thesis is to find a valid and practical model for a computer-based conceptual design support system. A prerequisite to building any design support system is a proper understanding of the design process. Hence, a survey of current prescriptive, descriptive, and computational models of the design process is presented. Initially, it was thought that the various stages of the conceptual design phase, such as function decomposition, solution generation, and evaluation, can be addressed independently. However, from the initial investigations in this research programme, it was soon realised that these stages are heavily inter-related and, therefore, the conceptual design phase should preferably be studied as a whole. Established prescriptive models of the design process (design methodologies) have been carefully studied and evaluated, with the help of a number of case design problems. A number of limitations have been encountered with these models, and therefore, a more realistic design model, which overcomes some of the limitations of established methodologies is proposed. Based on the insights gained from the theoretical studies, and the empirical investigations of other researchers, a model of an interactive design support system is described and fully explored. A novel high-level programming language, which can easily be used to define procedural models of engineering design, has been devised. This language, which will be referred to in this thesis as the Design Procedures programming Language (DPPL). A prototype Conceptual Design Support and Analysis System (CODSAS), which embodies the above model has been implemented. CODSAS provides an integrated, consistent framework for carrying out (conceptual) engineering design.
