Process Modeling of Top-down Collaborative Assembly Design Based on Petri Net

摘要

The top-down collaborative assembly design is a high parallel,dynamic and stochastic process. A concise design process model should be explored for effective process control and the system design of the top-down collaborative assembly design. In this paper the activity characteristics of top-down collaborative assembly design are analyzed,the typical sub-process models of collaborative design activities are constructed using Hierarchical Object-oriented Petri Net (HOOPN). The activity process of the top-down collaborative assembly design is modeled and the system architecture framework is built based on the activity process model.
