A multi-agent model and its speech act theory for cooperative mechanical CAD

This paper discusses a multi-agent and its speech act theory supporting cooperative mechanical CAD. The multi-agent is constructed with organizer, agents and communication manager. The structures of the organizer and agent are elaborated. The communication manager consists of central management and dialog management. This speech act theory supports the agents communication involving more than 2 people. The Pr/T net of speech act and firing rules are presented. The multi-agent model has been put into practice of computer integrated autobody development, and make the distributed cooperative autobody design system more flexible and coordinate.
