摘要
为了适应 CIM环境下生产的动态变化 ,有必要建立柔性的工艺计划 ,确定可替换的工艺路线。本文首先建立了包含加工规则的 Petri网模型 ,在此基础上构造了网状的柔性工艺计划 。
Due to the dynamic change in CIM environment, it is necessary to make a flexible process planning. In this paper a rule-based Petri net is developed from which a flexible process plan Petri net can be abstracted. Then the alternative operation sequences are determined using the T-invariant method. An example is used to demonstrate the procedure.
