摘　　要：在产品生命周期中,BOM贯穿了设计、工艺、制造、计划、采购、销售、财务等几乎所有职能部门,各部门按照本部门的需要定制了各种BOM。在BOM的定制过程中往往没有统一的设计和管理规范,无法保证各BOM之间数据的一致性,这种现象严重影响了企业产品设计、生产和管理等过程的集成和效率,增加了产品生产成本、延长了产品开发周期,所以研究基于STEP标准的统一BOM模型对制造业信息化的进程具有十分重要的意义。文中首先剖析了企业中存在的多视图BOM,阐述了BOM多视图的演变过程,在此基础上提出了统一BOM模型,并基于STEP标准构建了统一BOM模型。实践证明,文中提出的基于STEP标准的统一BOM模型可以较好地解决多视图BOM的模型不统一问题。During the product life cycle, BOM runs through almost all departments including designing, process planning, manufacturing,ordering, sale and finance, which make their own BOM according to their needs. However, so far there is no unified designing and managing standard to make BOM. To make it worse, there is no way to guarantee the unity of all BOM data. Such a situation in manufaeturing industry greatly restricts the efficiency and integration of designing, manufacturing and managing. What＇ s more, it increases product cost and lengthens product exploring cycle. This gives necessity and great importance to the research on the unified BOM model based on STEP in the informatization in manufacturing industry. So analyses multi - view BOM in enterprise and illustrates its evolution first,then poses a unified BOM model and based on STEP it constructs one. It proves that the unified BOM model based on STEP can achieve unity among multi - view BOM.
