摘　　要：针对通常MRPⅡ/ERP系统中由于产品结构数据和生产过程数据没有完全集成而造成物料需求、能力需求和计划调度等相关的生产活动被分隔考虑的情况,提出了基于生产计划的PPGBOMP模型,将静态的产品结构数据和动态的生产过程数据统一在此模型中,并引入通用生产结构(GPS)来表征零部件齐套过程跟踪中物料清单和过程清单之间的物料逻辑关系。GPS为不同层次的产品结构、多样性参数及不同取值的产品变型提供了一个通用的表示方法。通过采用参数取值约束的形式来定义分解规则和计划规则,对所有的多样性参数都利用产品所分解的最低层物料编码来进行赋值,从而大大简化了多样性表示中不同变量间的协调问题,并利用多样性参数及其取值的集合实现了产品变量与其操作变量之间的一致性。In traditional MRPⅡ/ERP systems, some production activities such as material requirements, capacity requirements and production planning are out of joint because of the incomplete integration of the product structure data and the production process data. To solve this problem, a PPGBOMP model based on production plans was proposed. The static product structure data and dynamic production process data were united in PPGBOMP. GPS （generic production structure） was introduced to represent the material logical relationship between BOM（bill of material） and BOP（bill of process） in tracking component kitting process. GPS provides a genetic expression of variant products with different-level production structures, diversity parameters and values. Definition of decomposition rules and planning rules with the form of constrained parameter assigns all parameters to the lowest- level materials of product disassembly structure and simplifies the harmonization of different variables. The consistency between product variables and operation variables is guaranteed by the diversity parameters and their values.
