In the 5th chapter, the application of Multi-Agent technology in Concurrent Engineering is studied. With the shaft strength and rigidness analyzing agent and gear strength analyzing agent as examples, an agent model is studied and provided. A federated multi-agent infrastructure based on product assembly model and multiple analyzing agents is suggested. By this, cooperation under distributed and heterogeneous environment and efficient information integration among mechanical geometry product modeling system, assembly modeling system and analyzing system can be realized.
