PDM (Product Data Management System, namely: product data management system) and ERP (Enterprise Resource Planning, namely: enterprise resource planning), is currently involved in advanced manufacturing technology, enterprise management groups are two important areas of technology. In theory, PDM able to integrate and manage all product-related information and product-related processes. It can help enterprises to construct a computer operating environment for the integration of heterogeneous application platform, for "extensive" development of a variety of individual computer-aided techniques, "intensive" management. ERP at the MRP-II was developed on the basis of advanced business management model. ERP further draws on modern management thinking on the business activities and manufacturing of all resources and processes related to unified management of the target to fully reflect the cost control to quality control and customer service management, focusing on corporate manufacturing quasi-continuous field of computerized management, mainly for the production of the manufacturing stage and logistics management. While the focus in the management of PDM and ERP are different, but because of the formation of the same product cycle, two areas related to PDM and ERP, so pairs of PDM and ERP system integration studies, for the effective shortening of product development cycles, accelerate product design the conversion of areas to manufacturing, thus, fundamentally promote the company's modernization process of great practical significance.
The difference between PDM and ERP and contact
Product data management (PDM) technology, was born in the early 20th century, 80, formally proposed the concept of PDM in the late '80s. PDM industry there is not a uniform definition. In February 1995, focuses on integration of PDM technology and related computer technology, international consulting firm CIM data in its release of "PDM Today" an article on the PDM proposed a simple definition:
"PDM is the one used to manage all product-related information (including part information, configuration, documentation, CAD files, structure, and permissions information, etc.) and all product-related processes (including process definition and management) technology."
While another well-known international consulting firm Gartner Group Inc., in its market research report, put the PDM is defined as:
"PDM is the design and production for businesses to build a concurrent product development environment (from the supply, engineering design, manufacturing, purchasing, sales and marketing, customer mix) is a key enabling technology. A full-fledged PDM system enables all those involved in creating, sharing to maintain design intent throughout the information life cycle in freely sharing and delivery of all product-related heterogeneous data. "while the ERP is a business and manufacture of all resources and processes for unified management of technology, focusing on manufacturing logistics management, its representative functions are: master production scheduling, material requirements planning, raw material procurement planning, job shop plans, tooling equipment, management, financial systems management, inventory management. Therefore, PDM and ERP systems components include dynamic (process) and static (PDM is mainly described in the product status information, geometric topology, and the logical relationship between information, ERP is the main equipment, teams and groups, workshops, funding, inventory and other manufacturing resources), two aspects, therefore, in order to achieve the field of information represented by PDM and ERP, as represented by the integration between the manufacturing, we must effectively play system, "1 +1? 2" under the premise of integration, in the global information sharing and process goals on a consistent basis, to fully meet the PDM and ERP system in both static and dynamic requirements. In order to achieve this goal of system integration, we must first of PDM and ERP in the management of objects, the role of the field, management ways and means the difference between such areas and contact with system knowledge.
1.1 The difference between PDM and ERP
a. Capture Product Definition Data
PDM system, the first and most important function is to capture and share any kind of product definition data. The function of being throughout the entire enterprise, from product design life cycle began to play a role in the early stages, but the key to the ability of this ERP system, it can not be adequately demonstrated.
Effectively capture engineering data
PDM systems typically provide application programming interface (API) developer kit to allow for a variety of design, manufacture, analysis software interface to build applications. This unique tool allows system integration engineers to connect almost all PDM user-oriented functions to meet the need for specific software design tools for the implementation of specific data management requirements. For example, modern CAD tools can be created with various forms of inter-related documents and has a "product model." When the designer to modify the components, the associated assembly, sub-assembly and the corresponding graphics file and create the file will do the appropriate changes. Through the actual application program interface, PDM system can grasp the relationship between them and the entire design process, track its status information. In contrast, the existing ERP systems are not easy to customize.
