面向对象的Petri网方法及其在软件工程中的应用

OBJECT ORIENTED PETRI NET METHOD AND ITS APPLICATION IN SOFTWARE ENGINEERING

本文介绍了面向对象Ｐｅｔｒｉ网（ＯＯＰＮ）方法，给出了ＯＯＰＮ的基本定义和图形表示，讨论了ＯＯＰＮ的特性和子网细化方法。结合软件设计开发周期，给出了ＯＯＰＮ在软件工程中的应用方法及步骤。给出了利用ＯＯＰＮ方法进行柔性制造系统（ＦＭＳ）控制软件设计开发的应用实例，并给出了部分对象类和应用程序。利用ＯＯＰＮ方法可以对软件系统设计开发过程进行有效的控制，保证软件系统的可靠性和规范化水平。

In this paper Object-Oriented Petri Net (OOPN) method is introduced. The basic definitions and graphical denotations are presented. The characteristics and subnet refinement method of the OOPN are given. In consideration of software design and development life cycle, the method and application steps in software engineering using OOPN are formulated. An example of the design and development of control software for flexible manufacturing system using OOPN is given. Some of the codes for the object class and application programs are also presented. The using OOPN in software engineering will improve the efficiency in controlling the software system development process and ensure the reliability and standardization of software system.
