A computer-based adaptive associative memory in support of design and planning

Continuing research on the organization and functionalities of a type of computer-implemented associative memory is discussed. The associative memory in question is being created to serve as part of a feature-based design system used primarily in support of the design, fabrication planning, or inspection planning of discrete mechanical machine parts. The development work is consonant with prior related work in the realm of case-based reasoning, especially as related to the role of memory in design. The associative memory innovations are in the use of fuzzy sets and neural net computing in the representation, storage and retrieval of design, fabrication, inspection, and materials knowledge. A considerable portion of the associative memory has been designed and implemented, and retrieval of previous designs on the basis of qualitative geometry has been demonstrated. Ability to explore materials composition with the objective of meeting critical materials properties constraints has been demonstrated.<
