Concurrent Hierarchical Model and Analysis Based on Fuzzy-Timing Petri Net
In order to simplify the workflow and make efficient use of resources in workflow management, a hierarchical concurrent model based on fuzzy-timing Petri net is proposed. To analyze complicated structure with layered approach, this model turns a complex concurrent network structure into order structure, which simplifies the entire workflow. Proof of the feasibility and correctness of the model is given and verified by an example. In the example, minimum processors are used to deal with corresponding activities, without changing the duration of the case, therefore system resources are efficiently used.
