The Research On Information Integration Between PDM And ERP Under CIMS Circumstance

As the important part of design automation sub system, management and strategy sub system in CIMS, RDM and ERP have come to be the key factor to manage the whole product definition and its lifetime. The information integration between PDM system and ERP system in CIMS would show great practical significance to CIMS implementation, product designing and manufacturing process optimization.After analyzing the product data exchange and share among CAx, PDM and ERP, this paper expounded three arrangements of ideas to carry out system integration between PDM and ERP at present, then, broadly Combining with the last research achievements of information integration theory and method and synthetically considering technical advancement and practical needs of domestic medium and small-scale enterprises. advanced and analyzed three plans to solve the integration problems. In view of reasonable method to organize product information, the paper adopted EXPRESS model language to describe integrated logic data structure, built integrated data model with O-O feature to support system integration, discussed the method to bring about integrated data model on RDBMS, and at last, according to the implementation of CIMS in Yunnei Power Co., Ltd, developed a integrated data model to exchange and share information between PDM and ERP by means of transforming EBOM to MBOM.
