【摘要】 把Petri网原理和面向对象技术相结合,定义一种对象Petri网。运用这种对象Petri网对可复用的电力系统软件体系结构进行描述。这种对象Petri网有面向对象技术的自然性和封装性,有严格的数学描述和直观图形表示;通过库所和变迁的连接关系及变迁触发、有色托肯的流动,能清晰、有效地描述可复用电力系统软件体系结构中不同层次的主体属性、行为及彼此间的信息交互、包含与被包含等的关系。它既能反映该体系结构中组件等主体间的静态联系,又能精确、方便地描述主体间的异步、并发等动态行为。更多还原

【Abstract】 Combining Petri Nets principle with object-oriented technology,define a kind of object-oriented Petri Nets which used to describe the reusable power system software architecture.The OOPN keeps the main characters of object-orientation,such as naturalness and encapsulation,and also acquires the Petri Nets′ characters such as rigid mathematics describing and intuitionistic graphics express.With the relation between place and transition,transition firing and stream of color token,OOPN can clearly and availably depict the attributes and operations of object,information intercommunication between objects and containing relations of different layers’ objects in the reusable power system software architecture.OOPN can reflect objects’ static relation in the architecture,but also can precisely and easily depict the asynchronous and concurrent dynamic behaviors among objects.更多还原
