CIMS environment of the Integration of ERP and PDM
Into the 21st century, CIMS (Computer Integrated Manufacturing System) has developed into a new information age enterprises production. CIMS for the early realization of inter-enterprise integration of manufacturing enterprises, providing technical support and integration tools, but the manufacturing process integration, and there is no outstanding CIMS concept. Modern CIMS aimed at improving the business-to-changing market environment, adaptability and competitiveness, greater emphasis on the integration of technology and management, so that the whole process of production to achieve optimal operation, organization and management more flexible and rationalized. Not only focus on manufacturing integration, but also in the breadth and depth with new development, information integration, based on the implementation process integration and inter-enterprise integration. Main applications of modern CIMS have the following characteristics:
(1) PDM information in the design automation sub-systems integration process has played an "integrated" framework of the role of individual applications (such as CAD, CAM, CAPP, etc.) through various means (package, application interfaces, etc.) as an independent objects integrated into PDM system;
(2) ERP instead of MRP as CIMS, the core of the operation and management decision-making. Therefore, they need to distinguish between two functions of the system, balancing its role and achieve its integration, to eliminate the difference between the "information islands."
Here's an integrated ERP and PDM analysis and research.
ERP and PDM integration of content
ERP and PDM Introduction
ERP (Enterprise Resource Product) enterprise resource planning, the main resources of the enterprise's logistics, capital flow and information flow of resources to conduct unified management of resources, its main management are: master production scheduling, material requirements planning, material procurement planning, job shop plans, financial systems management, tooling equipment management and inventory management. PDM (Product Data Management) product data management, key management are: electronic storage and document management, workflow and process management, product structure and configuration management, parts classification management, engineering change management and project management.
ERP and PDM information integration content
With the development of ERP and PDM, two systems of data and functions of the large number of cross-form the integration of the contents of the two systems (Figure 1). PDM system to ERP system provides information about product design, ERP system for the PDM system provides the manufacturing cost of the relevant information. PDM system will MBOM and Routing passed to ERP systems, ERP system based on the above information, to arrange the production and operation activities (such as feed, processing, assembly and cost accounting, etc.), collaborative enterprise among the various departments work. At the same time the information needs of ERP generated CBOM passed to PDM system, from the PDM system to manage and maintain. As business needs change, MBOM is no longer a one-way transfer from the PDM to the ERP, emerged from the ERP imperfect MBOM reverse pass to the PDM needs, imperfect MBOM in the ERP system, and then back to the PDM system perfect.
May wish to set up procedures for the process PP, engineering materials list is EBOM, manufacture of materials for the MBOM, then the
PDM manage data collection for A = (EBOM)
A collection of business information for the B = (MBOM, PP);
Workshop for low-level control data set C = (EBOM);
PDM and ERP is a collection of information on the intersection of A (B, C),
One set of ERP for the (B, C).
ERP is the core of MRP. In the ERP system, must be defined plant-level assembly of parts and the whole production process, this information through the planning view to manage the production and assembly, so it is for the product and production process, is planned state; Similarly, the product mix is also a PDM the center of design engineers designed the project view, more emphasis on the product's features and how conscientious configuration, product structure and the corresponding documentation and design processes together, we offer a complete product-oriented definition, is the design state. Therefore, PDM and ERP system, the intersection of the two is a list of product manufacturing BOM and process matrix. With the continuous expansion of the two systems, more and more enterprises will integrate the two systems together through the product structure. |
