Information Based On The Unified Bom Model In The Step Standard And Pdm / Erp Integration

Following the development in information technology, informationizing has been the core to improve their product competence in manufacturing enterprise. As the basic data in informationization systems in manufacturing industry, BOM is the bridge between the department of project designing, product manufacturing and managing, which is also the key and main content of the information integration in PDM system and ERP system.During the product life cycle, BOM runs through almost all department including designing, process planning, manufacturing, ordering, saleing 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, all BOM except EBOM and PBOM, are setup on handwork, which has no way to guarantee the unity of all BOM data. Such a situation in manufacturing industry greatly restricts the efficiency and integration of designing, manufacturing and managing. What's more, it increase 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.Directed to the disunity of BOM model in the present BOM research, this research, based on the practical needs of the CIMS implied exemplary project in Yunnei Power Co., Ltd, is to discover a unified BOM model based on STEP and through such a model to explore a practical means to achieve the information integration between PDM system and ERP system. It analyses multi-view BOM in enterprise and illustrates its evolution firstly, then it poses a unified BOM model and based on STEP constructs one. What comes next is to analyses the content and patterns of information integration between PDM system and ERP system, according to the unified BOM model based on STEP, it puts forward a practical means to achieve the information integration between PDM system and ERP system. Finally, through exploring an integration example, the research achieves the transition from the EBOM in PDM system to the MBOM in ERP system.It proves that the unified BOM model based on STEP can achieve unity amongmulti-view BOM and the means based such a unified BOM model to achieve information integration between PDM system and ERP system feasible and effective.
