Abstract: To solve the problems such as low efficiency of man-machine interaction and disability to cope with requirement changes caused by complex configuration and so on in virtual assembly systems,a virtual assembly model based on Agent was proposed,which constructed a bottom-up virtual assembly scene by considering each assembly part as an individual agent.From the viewpoint of each part,the assembly knowledge model was constructed,which included some parameters for describing parts and features.Meanwhile,serials of message templates for transforming context information between agents were also defined.To help agents make proper decision,a decision tree was built based on the process of virtual assembly,by which agent could choose its next step with received messages and relevant parameters.Experiment showed that the proposed assembly model could accurately understand the users intention according to the context-aware.

Key words: virtual reality, virtual assembly, context-aware assembly, multi-agent system
