摘要
首次提出面向复杂产品研发的分布协同系统多层次Petri网模型。以新支线飞机ARJ21的分布协同研发系统为例,模型通过粒度清晰化实现知识流程的分层,通过可达性检验发现研发整体流程和模块开发子流程中的瓶颈与障碍,进而实现了系统流程再造,提高了研发效率。该方法突破以往的经验设计思路,实现了研发系统设计的科学化与工具化。
For a complex product research and development（RD） system,a new multilevel Petri net-based distributed collaborative RD system model is constructed,as demonstrated in ARJ21＇s case.Upon the granularity,the adaptive hierarchical organization for knowledge flow is achieved,and by the analysis of reachability,the bottlenecks in knowledge process are discovered,which realizes system process reengineering and improves the efficiency of RD.The new method provides the programmed tool for RD system design instead of by experience.
