PDM与ERP系统之间信息集成的实现方法

提出了一种产品数据管理(PDM,Product Data Management)与企业资源计划(ERP,Enterprise Resource Planning)系统间的信息转换方法以及信息集成方式.分析了PDM与ERP系统集成信息,定义了包括物料、产品的层次结构及资源的集成信息模型.通过组合、删除、调整、分解4种物料清单(BOM,Bill of Materials)结构转换算子以及继承型和派生型2种BOM属性映射方法,讨论了设计BOM经由工艺BOM向制造BOM的转换机制,实现了PDM与ERP系统间集成信息的信息传递与同步操作.通过一个PDM与ERP系统间集成信息转换的应用实例,对所提出的集成方法的应用进行了说明.该方法为PDM与ERP系统集成的研究提供了一条可行的解决方案.

Implementation approach to information integration between PDM and ERP systems

An information conversion and integration method between product data management(PDM) systems and enterprise resource planning(ERP) systems was presented.Based on the information in PDM and ERP systems,an integrated information model was built to describe the information of materials,product hierarchical structures and resources.The information transformation and data synchronization between the two systems were addressed by developing a conversion mechanism,with which an engineering bill of materials(BOM) can be converted to manufacturing BOM via process planning BOM,so as to achieve information semantic unification between the two systems.The mechanism consisted of four BOM structural conversion operators including composition,deletion,reorganization and decomposition,and two BOM property mapping methods of inheriting and deriving.The implementation of the proposed method was illustrated with an application practice of information integration between a PDM system and an ERP system in a specific enterprise.This integration method provides an effective way for further study of PDM and ERP integration.
