摘　　要：提出了一种面向对象petri网[OPNs]的建模方法:针对电机生产系统设备种类多,加工工艺复杂等特点,在模型构建过程中融入了面向对象的抽象机制,提高了系统模型的通用性及扩展性,同时降低了模型的复杂度;在定义了电机生产系统OPNs模型类及对象子网间消息传递模式的基础上,用实例描述了基于OPNs的电机生产系统的建模过程,并运用Witness仿真软件对系统模型进行仿真。This paper proposes a modelling method of object-oriented Petri nets .To deal with the complexity of the motor production systems,object-oriented abstraction mechanisms such as encapsulation and classification are combined into the OPNs model to enhance the system model′s expansibility and reduce its complexity.On the basis of defining the motor production systems′ OPNs model class and models of messaging between object-oriented submodels,a case is presented to illustrate the modeling of motor production systems with OPNs,and simulation software Witness was used to simulate the system model for the realization of optimizing the motor′s product process planning.
