Abstract :
Performance analysis for workflow models has been recognized as one of the most significant tasks in workflow management. Time performance evaluation methods are needed for workflow designers to estimate the average turnaround time of processes in the early stage of workflow system development. Based on extending fuzzy temporal workflow nets by introducing choice possibilities for transitions in structural conflict, a new workflow model named extended fuzzy temporal workflow nets (EFTWF-nets) has been proposed. And the calculation of temporal elements in EFTWF-nets is given. Then a decomposition algorithm for EFTWF-nets is put forward and a time performance evaluation method based on it is investigated. Finally a case study is given to illustrate how to use this approach
