|Abstract:||Since engineering design usually involves a lot of trade-off and decision making, it is a complicated and time consuming process. To augment engineer's creativity, a case-based multiattribute structural design and optimization methodology is developed in this study. This new methodology is aimed to solve the problems in computer aided structural design in customizing user (designer) knowledge and preferences, machine learning, automatic creation of design prototypes based on the previous design cases, and the incorporation of design evaluation and optimization in the design process. Utility analysis has also been used in structural design evaluation and optimization with consideration of earthquake uncertainty.
The methodology is an integration of artificial intelligence technology and decision theory, e.g. case-based reasoning, expert system technique, and multiattribute utility analysis. Especially, a two-step case selection algorithm and a design evaluation and optimization algorithm are developed by using utility theory. The methodology is implemented into a computer prototype called CMASDOS (Case-based MultiAttribute Structural Design and Optimization System) with object-oriented programming. The feasibility and creativity of the methodology are verified through design examples.
