The major building blocks needed in the CDST were individually analyzed, including: knowledge acquisition procedures; knowledge representation techniques; automatic design approach suitable for computer implementation; decision-making logic adapted to a multiobjective environment; and design process control logic relying on existing artificial intelligence techniques. A possible hardware and software configuration based on existing resources was derived, and a mock-up of a simplified CDST was developed and implemented so that hands-on experience on each major aspect can be obtained. A working plan for a phased/expandable development of the CDST was produced. 收起
