摘　　要：时间性能的定量分析是保证流程模型有效性和提高业务流程质量的关键。针对管理型流程的特点,基于任务活动执行时间为零或者服从指数分布的假设,建立了业务流程的广义随机工作流网模型,并利用广义随机Petri网和马尔可夫链理论来分析流程的时间性能,获得了流程平均执行时间的计算公式,最后给出了应用验证实例并和仿真结果进行了比较。Quantitative analysis of time performance is key to guarantee the validity of business process model and to improve its quality. Based on the characteristic of management processes and the assumption that the execution time of activities is zero or obeys the exponential distribution, the Generalized Stochastic Workflow Net of business process is constructed, which facilitates the analysis of time performance through the theories on Generalized Stochastic Petri Net and Markov Chain. Then the computational formula of the average execution time of workflow is deduced. Finally, a case study is given and the computational result is compared with that of simulation.
