摘要
业务流程管理中的时间约束(TC)分活动执行和活动结束两类,前者TC活动的开始执行时间不得迟于该时间约束指定的时刻,后者TC活动的执行结束时间不得迟于该时间约束指定的时刻。结合BizPro系统,其时间约束和异常处理建模,采用符合执行定义信息的基于XML表示法或完全等效的基于业务流程表示法。时间约束的实现依赖于流程中TC活动和参照活动的执行状态,涉及业务流程实例线程和时间约束监听线程。
Time constraint (TC) in business process management system (BPMS) can be divided into schedule time constraint and implement time constraint. The former, beginning time of TC activity is early as appointed time of schedule time constraint, and the latter, ending time of TC activity is early as appointed end time of implement time constraint. Modeling methods for TC and exception handling in the BizPro system were applied, them are up to the XML representation and equivalent business process representation defined by implement time constraint. TC was implemented by according to implement states of TC activity and reference activity, and thread of business process example and monitoring thread of TC.
