摘　　要：针对制造执行系统(MES)的核心模块——车间生产调度模块,利用对离散动态系统具有准确描述能力的着色Petri网(CPN)对车间生产进行了抽象和建模;通过向网系统中引入规则约束,为车间内的动态事件和扰动提供了动态调度。为了实现MES生产调度模块的易集成、快速重用性,提出了利用分布式组件(DCOM)技术将车间调度模型封装为车间调度器的实现方法。According to the kernel module of the manufacturing execution system （MES）-workshop production scheduling module, the abstraction and modeling for the workshop production are performed by using coloured Petri net （CPN） which has precise description capibility for discrete dynamic system. The rule constraint is introduced in net system and it can provide dynamic scheduling for dynamic events and disturbances in the workshop. In order to realize ease integration and rapid reusability of MES production scheduling module, a distributed component （DCOM） technology is proposed to package the workshop scheduling model as the workshop scheduler.
