摘　　要：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。Object-oriented Petri Net modeling （OPN modeling） can be established by applying the technology of object-orientation and Petri net. According to the characteristics of production scheduling in discrete manufacturing system, OPN was chosen to build the system＇s scheduling model. Minimum cost in due time was selected to be the scheduling target, and then optimal method was used to optimization, Through being applied to model and optimize for FMS, this method is proved to be useful in showing the manufacturing path and resource obligation of production scheduling. Complex system can be abstracted by this modeling method, and the system model is easier to be expanded.
