摘要
本文针对顺序图形式分析上存在的困难,引进消息事件序约束的概念,利用Petri网理论定义了顺序图的分析模型,并给出了UML顺序图冲突和语义一致性的检查方法,最后通过一个实例说明了方法的使用。实例表明,该方法是可行和高效的。
A formal semantics of the UML sequence diagram based on the Petri net theory is defined based on the Message Event Sequence Constraint. The algorithm for the check of consistency and collision is given. Finally, the effectiveness and practicability of the method are demonstrated by an example.
