| 摘 要： | 维修作业过程模型是进行装备虚拟维修性分析与维修训练的基础。维修作业过程属于典型的离散事件,Petri网方法相对于其他过程建模方法,更适合于描述具有冲突、并发关系的离散事件系统,且模型具有直观性。利用时间-有色Petri网对装备的维修作业过程进行建模,分析讨论了维修作业过程中逻辑关系的表达与维修保障资源的描述;引入对象概念对资源库所进行了扩充,定义了维修作业变迁的触发条件及触发延时的确定方法,增强了模型的描述能力。最后通过一个维修作业实例,说明了该模型可以很好地应用于装备维修作业过程建模。

| Abstract: | The maintenance task process model is the basic of virtual maintainability analysis and maintenance training.The maintenance task process as a typical discrete event system,is appropriate to be modeled with Petri net,which has capability to describe the discrete system with conflicts and concurrences.A timed-colored Petri net is used in the modeling of equipment's maintenance task process.The expressions of the maintenance tasks relations and maintenance resources are discussed;a resource place extended wit... |
