基于通用物料清单的PDM与ERP集成

Integration of PDM and ERP Based on the Generic Bill of Materials

产品数据管理(PDM)和企业资源计划(ERP)是制造业实现计算机集成制造系统的重要技术支撑,现有的系统集成主要基于工作流和产品物料清单(BOM)。前者受工作流节点的限制无法实现数据的实时更新,后者仅集成产品结构数据,无法满足基于多样化顾客需求的变型设计模式。基于通用物料清单(GBOM)创建包含产品配置信息的完整产品结构,通过建立产品零部件(Item)和GBOM的中间文件完成PDM和ERP系统间的数据交换,实现系统集成。GBOM中的配置信息传递到ERP端,生产人员可根据顾客需求在ERP端进行产品配置,缩短产品的市场反应时间。集成方法在RMM3塑料外壳式断路器中的应用证明了方法的有效性。

Product Data Management （PDM） and Enterprise Resources Planning （ERP） are the important technical foundations of manufacturing to achieve Computer Integrated Manufacturing System. The integration of the two systems is mainly based on the work flow and bill of materials （BOM）. The former cannot update data real-time because of the restriction of work flow nodes; the latter integrated product structure data only which cannot meet the needs of variant design method based on the diversiform customer requirements. The complete product structure which includes the product configuration information was established based on the generic bill of materials （GBOM）. To accomplish the integration of PDM and ERP, the intermediate files of part （Item） and GBOM were set up for data interchange. The configuration information in the GBOM was transport to the ERP end, at which the production staff can configure product, the response time to market changes was shortened. A case study on RMM3 molded case circuit breaker （MCCB） illustrated the effectiveness of the proposed integration method.
