Visual Design Using Case-Based Reasoning and Multi-agent Systems

Abstract

This paper deals with case-based reasoning (CBR) which is adapted in the Computer Aided Design (CAD) system. The specialized CAD tools of the system allow the designer to visualize general ideas about projects in the form of design drawings and automatically transform them into graph data structures. The system’s library provides source cases representing previously created solutions. Designer’s requirements are represented by graph patterns and the case library is automatically searched for cases which fit these patterns. Target cases result from the cooperation among the human designer and intelligent software agents. The retrieved cases are evaluated on the basis of specific design knowledge the agents are equipped with. The presented approach is illustrated on the example of designing an indoor swimming pool.
