In this paper, we merge place node and transition node in Petri net, and reserve token element only by analyzing execution mechanism and dispatching principle of Petri net. In parallel design process instances, a sub-token is introduced, which avoids design process execution conflicts. The definition, dispatching model, and execution mechanism of product design p… Show more
