基于T-不变量分解法获取工作流中的序关系

摘要

工作流系统中活动之间的序关系非常有用，然而这些序关系的获取往往比较困难。讨论了运用T-不变量分解法获取序关系的可行性，并将sound自由选择系统中序关系的可获取性进行了推广。利用T-不变量分解法，可以获取一类sound非自由选择系统中的序关系。%　　The order relations between the activities in workflow systems are very useful. But it is rather difficult to obtain these relations. The feasibility of capturing order relations based on T-invariant decomposition technique is discussed, and then the accessibility of the order relations in sound free choice systems is extended. The order relations in sound non-free choice work-flow systems can be obtained using T - invariant decomposition technique if the workflow systems can be decomposed into sound free choice subsystems.
