Abstract:

For a complex product research and development (R&D) system, a new multilevel Petri net-based distributed collaborative R&D 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 R&D. The new method provides the programmed tool for R&D system design instead of by experience.
