On cooperation in multi-agent system, based on heterogeneous knowledge representation

Abstract

Graphs are an expressive representation of projects in the domain of computer-aided design (CAD). Such a representation of a problem’s structure allows for automation of a design process, what is an important property of CAD systems. It can be accomplished by using graph grammars which can represent a progress of a design process. In this paper we introduce a graph based approach to the synchronization of a design processes carried out by different and independent transformation systems supporting various aspects of a building project creation. Such a synchronization is necessary when two or more systems affect simultaneously a shared area. The proposed mechanism is illustrated by an example of successful synchronization on shared elements of an object being designed, achieved by using different representations at different layers of a design.
