【摘要】 Petri网是一种图形化的建模方法,具有直观、易用的特点,是业务流程建模常用方法。面向对象方法将对象通过消息传递关系组成一个系统,易于实现系统建模。结合两者的优点,提出了一种面向对象时间Petri网的建模方法,通过该方法建立的Petri网模型,可以避免传统Petri网复杂性等缺点,具有较好的模块性与封装性,在业务流程变动时降低了建模的复杂度与难度。更多还原

【Abstract】 Petri net is a graphical modeling method which is intuitive and easy to use.Petri net is a conventional method in business process modeling.The object-oriented method forms a system of the objects through message passing,which makes it easy to implement system modeling.Combining the advantages of both,the object-oriented time Petri net modeling is proposed.The Petri net models established through this method,with its good modularity and encapsulation,can overcome the complexity of the traditional Petri nets and other shortcomings,reducing modeling complexity and difficulty when the business process changes.更多还原
