面向对象Petri网将面向对象技术与Petri网相结合,利用对象的封装及继承等特性,降低了所建立系统模型的结构复杂性,增强了其可重用性和可剪裁性.系统的面向对象Petri网模型(OOPN)由对象模型(OPN)及对象联系模型(OCN)组成,前者描述对象内部的状态变化细节及与外部联系的接口,后者描述系统中各对象间的联系.分析了面向对象Petri网技术在各种复杂系统建模问题中的应用,并以电梯群控系统的建模为例,从电梯群控调度的角度,详细给出了OOPN模型的构建.
麵嚮對象Petri網將麵嚮對象技術與Petri網相結閤,利用對象的封裝及繼承等特性,降低瞭所建立繫統模型的結構複雜性,增彊瞭其可重用性和可剪裁性.繫統的麵嚮對象Petri網模型(OOPN)由對象模型(OPN)及對象聯繫模型(OCN)組成,前者描述對象內部的狀態變化細節及與外部聯繫的接口,後者描述繫統中各對象間的聯繫.分析瞭麵嚮對象Petri網技術在各種複雜繫統建模問題中的應用,併以電梯群控繫統的建模為例,從電梯群控調度的角度,詳細給齣瞭OOPN模型的構建.

Object-Oriented Petri Net (OOPN) was integrated by Object-Oriented Modeling (OOM) and Petri Net,as a result,the structure of system model was simplified and the reusability and scalability were enhanced by utilizing the encapsulation and succession of the object.The model of OOPN is composed of OPN and CPN,the former describes the internal specifics of the object and the interfaces between the interior and the exterior,the latter describes the relations among the objects in the system.This paper introduces the application of OOPN to system modeling,and shows how to build an OOPN model by modeling an Elevator Group Control System (EGCS) with a consideration of the scheduling of Elevator Group Control.
