| 中文摘要 | 针对不确定性情况下工作流时间分析的实际需求,基于可能性理论,引入模糊时间的概念,提出了一种扩展模糊时间工作流网,以便对不确定性时间信息进行全面描述。在考虑不同流程活动之间存在资源约束的情况下,提出了基于扩展模糊时间工作流网的多个并行流程建模方法。同时,分别讨论了扩展模糊时间工作流网模型中模糊时间和变迁触发可能性的模拟,提出了模型的仿真分析方法。最后,以某制造企业为例,采用CPN Tools进行建模和仿真分析,验证了方法的有效性。; To deal with the practical need for uncertain time modeling and analysis in workflow management systems,concept of fuzzy time based on possibility theory was introduced and Extended Fuzzy Timing Workflow Nets(EFTWFN) was put forward,which was used to describe all uncertain time information in a workflow.Modeling method to construct the EFTWFN models of concurrent workflows with resource constraints was proposed considering resource constraints among several different flow activities.Simulation procedure of fuzzy time and transition firing possibility of EFTWFN models were discussed,which were the foundation of the simulation of EFTWFN models.Finally,an application of the modeling and analyzing methods were illustrated through an example in a manufacturing enterprise and the validity of methods was demonstrated based on the simulation by CPN Tools.; 国家自然科学基金资助项目(60674080); 国家863计划资助项目(2006AA04Z151,2006AA04Z166)。~~ |
