针对 ＣＩＭ环境下单件小批量生产计划的“大设备平衡”这一核心问题，研究并实现了一种基于ＣＰＭ与专家经验相结合的ＰＰＣＥＳ专家系统。首先研究了求解这一问题的数学模型、约束条件和目标函数，设计了求解问题的专家系统解决方案，并与 ＭＲＰ Ⅱ实现了信息集成，最后给出了 ＰＰＣＦＳ在典型单件小批制造业哈尔滨电机厂 ＨＥＣ—ＣＩＭＳ 工程中运行实例，结果表明本系统能方便、灵活地处理生产计划的“大设备平衡”这一核心问题，有效地解决了 ＭＲＰ Ⅱ对此类生产类型的不适应性。
Aiming at the core issue of “large equipment balance” in single-lot and small-batch production planning in CIM environment, a PPCES expert system based on CPM and expert experience is researched and implemented. First of all, the mathematical model, constraints and objective functions for solving this problem are studied. The solution of expert system is designed and the information integration is realized with MRP Ⅱ. Finally, The results show that this system can handle the core issue of “big equipment balance” in production planning conveniently and flexibly and effectively solve the incompatibility of MRP Ⅱ to such production types.
