摘要
针对协同设计中任务的执行流程缺乏柔性,不利于分析实际设计过程的现状,提出一种单元调用变迁对与决策变迁相集成的基于对象的扩展Petri网,扩展了Petri网的可达图以适应分析OEPNs模型.采用OEPNs中的过程网和单元网对协同设计过程建模,利用模型中的单元调用变迁对和决策变迁对过程本身和可能状态进行分析.最后与相关的研究工作进行比较并给出了结论.
A cooperative design task is lack of the flexibility of executing flow, which is not suitable for analyzing practical design process. An object-based extended Petri nets which integrats the units call transition pairs and decision transition is proposed. The reachable graph of traditional Petri nets is extended to meet the analysis of OEPNs. The cooperative design process is modeled by using process nets and unit nets, its properties and potential states are analyzed by using units call transition pairs and decision transition. Finally, the research results are compared with other works proposed in literature and the corresponding evaluation is given.
