将面向对象技术与Petri网结合作为建模工具,针对离散制造业的研究现状及其生产调度特点,进行离散制造系统生产调度建模;选用满足交货期的成本最低原则作为调度目标,运用最优化方法进行目标优化。通过对FMS的建模及目标优化,证明利用该方法建模能准确反映生产调度的加工路径及其资源约束,将复杂系统高度抽象,模型易于扩展。 The combination of object-oriented technology and Petri nets as a modeling tool for discrete manufacturing industry research status and production scheduling characteristics of discrete manufacturing systems for production scheduling modeling; selection of delivery to meet the minimum cost of the principle of scheduling as the goal, the most Optimization method to optimize the target. Through the modeling and optimization of FMS, it is proved that the modeling of this method can accurately reflect the processing route of production scheduling and its resource constraints, abstract the complex system and extend the model easily.
