RESEARCH ON THE TECHNOLOGIES OF FULL-SCALE ENTERPRISE INFORMATION'S INTEGRATION BASED ON PDM

摘要

By helps of the platform of PDM, integrating all kinds of enterprise information supporting product development will result in the share of information where the flow of information is in a orderly and controllable state, which is very important in product development. According to the implementation of PDM in a heater LTD Company of Huangshi and the cognition of Product Manage from IBM, the frame of full-scale enterprise information integration is put forward in the paper, and the relation between PDM and CIMS, CAD/CAPP/CAM, ERP and manufacture based on web is analyzed. Meanwhile, the model of information integration based on PDM, including the model of encapsulation, interface and integration, is further researched. Combined with the model of information sharing based on STEP, this paper tries to take full advantage of PDM so as to solve some problems as following: Firstly, how to organize, manage and control the information formed in engineering design; Secondly, how to realize the exchange and share of information between different subsystems in CAD/CAE/CAPP/CAM; thirdly, how to integrate information between CAX system and MRP-II. All these provide full-scale enterprise information integration with a common model and effective methods.
