摘要：
Time information management in workflow has been recognized as one of the most significant tasks in workflow management. The uncertainties in time and time-related constraints in workflow models should be taken into consideration. Based on introducing time constraints on elements in Fuzzy-timing Petri Nets ([1],[2]), this paper has proposed a new workflow model named Fuzzy Temporal Workflow Nets (FTWF-nets). The calculation of temporal elements in FTWF-nets is given. Then time modeling and time possibility analysis of temporal phenomena in FTWF-Nets are investigated Finally an example is given to illustrate how to use these methods. Research results show that FTWF-Nets can be used to model time information in those workflows which have time uncertainty and have time constraints on resources and activities, and analyze the time possibility on some constraints.
