Abstract: To tackle the modeling of collaborative design process with a parallel execution process of multi-Agent in design task and dynamically uncertain design process, by analyzing collaborative model of entire collaborative design process of mechanical products, procedure control network model in collaborative process based on object-oriented Petri net was defined. The meta models of investigating and establishing item phase, original design phase, scheme design phase, general design phase and part design were formally described. Based on meta-model invoking strategy, invoking transformation and auditing decision transformation in design phase of meta model were bounded, and procedure control mechanism in mechanical products collaborative design process was proposed. Moreover, routing strategy of procedure control network was also introduced. Finally, general design of meta model invoking of mechanical products was taken as the example to demonstrate that the proposed method was effective in dynamic control of collaborative design process.
