Abstract

Design expert systems include heuristics which combine technical engineering expertise with necessary assumptions for evaluating alternatives during the iterative design process. These assumptions might be reasonable, but become less useful as the design evolves and progressively more precise tradeoff choices must be made. This paper presents a method for construction of an expert system which treats expertise in formal decision theory with the same respect accorded to technical domain expertise. A quantitative assessment of the end-user's preferences is used in merit-level decision rules which direct the design process. An automotive material selection example is presented.
