Knowledge-Based Design Using the Multi-Modeling Approach

Abstract

This paper deals with the use of multiple models for design tasks. In particular, it shows that the multi-modeling approach can offer a valid background for facing some of the fundamental problems involved in the development of knowledgebased systems for design. After an introduction to the design task and an analysis of the main open problems, the issue of using multiple models for design is discussed. Later, a survey of the multi-modeling approach to the representation and reasoning about physical systems is presented. The standpoints of the proposed approach to design are then illustrated, and the specifications of an experimental prototype, called CDM, are discussed. The architecture and the general mode of operation of CDM are presented, and the techniques used for organizing and representing domain knowledge are illustrated. A sample design session with CDM is discussed in detail.
