摘要
业务实例的时间性能是业务过程实时管理和调度的重要依据.业务实例的可达子网随着执行推进不断变化,其中各个活动分别处于完成、执行和等待等多种不同的状态,业务实例的性能估计只能针对该子网进行.本文首先提出执行中和等待中活动的时间性能等价模型,提出实例的归属子图集概念以跟踪实例的可达子网的动态变化,并将复杂的实例时间性能求解问题转换为更为简单的归属子图的性能求解问题,用一个例子演示了业务实例性能分析过程.
Time performance of business process instances is important basis for real time business process management and scheduling.The reachable subnets of business process instances continually change in accordance with progressing of instances,in which activities are in states such as completed,executing or waiting respectively,and performance of instances can be analyzed merely based on it.Firstly,a performance equivalent model for waiting and executing activities was proposed,subsequently,the concept of potential instance subgraph set was proposed to trace the dynamic change of reachable subnet of business process instances,and the complex problem of performance analysis for business process instances was decomposed to simpler ones for potential instance subgraph.Lastly,an example was given to demonstrate the process of performance analysis for business process instances.
