Modeling and Reasoning of Task Collaborative Allocation Using Object-Based Fuzzy Petri Nets

To cope with the problems that the model's size is increased rapidly,functionality of colored fuzzy variable is limited and the knowledge classification can't be represented in modeling of FPN/FCPN and reasoning process,an improved object-based FPN modeling and fuzzy reasoning algorithm was proposed. The object-oriented technique is used to simplify the large-scale FCPN,and the simplified FCPN could be degenerated into an original FPN while changing the semantic of tokens.It not only represents the fuzzy language variable set,but more important,it also can be regarded as the reference of other FCPN.Finally, the method is applied to the fuzzy inference procedures for the ask allocation in collaborative design environment,and shows that the method reduces the model complexity efficiently,and the objectified model is intuitive and easy to be understood.
