摘要: 在对模糊时态工作流网引入选择概率函数的基础上,提出了扩展模糊时态工作流网的工作流模型,给出其中的时态元素计算方法,以及分解扩展模糊时态工作流网的算法,并讨论了基于该分解算法的时间性能评估方法。最后,通过一个实例阐明了如何使用该时间性能评估方法。

Abstract: By introducing selective possibility functions to Fuzzy Temporal WorkFlow nets (FTWF-nets), a workflow model named Extended Fuzzy Temporal WorkFlow nets (EFTWF-nets) was proposed. And the calculation method of temporal elements in EFTWF-nets was provided. Then a time performance evaluation approach by decomposition of EFTWF-nets was studied. Finally, a case study was given to illustrate the usage of this approach.

Key words: performance evaluation, workflow model, Petri net, fuzzy temporal workflow nets
