A Fuzzy Critical Path Method based Scheduling Approach for Collaboration Process

The temporal uncertainty of activities and limited resources are important factors for successful operation and performance evaluation on collaborative design. In the paper a method of modelling well-define collaboration process based on workflow technology, probability theory and fuzzy-timing high-level Petri nets is presented. Then while an approach for identifying the fuzzy critical path is given, a policy of solving resource conflict and resource scheduling with limited resources is introduced. These approaches offer theoretic basis and available means of time management, resource scheduling and conflict solving in collaborative work processes. Finally, the validity of those proposed methods is proven by an example
