The Chinese name of PDM manages for product data (ProductDataManagement) . PDM is one uses government all related to the product information (include information of file of spare parts information, configuration, documentation, CAD, structure, attributive to wait) and all related to the product process (include to the process is defined and manage) technology. The setting that PDM produces is in of 20 centuries 60, 70 time, the enterprise begins to use the technology such as CAD, CAM in its are designed and producing a course, the application of new technology also brought new challenge while stimulative productivity develops. To creating a company character, although each unit computer assists a technology to had matured increasingly, but become a system oneself, the information that rare effect lacks between each other is shared and use, form so called " information Gu island " ; And develop at full speed as what the computer applies, subsequently and all sorts of data that come expand quickly also, form enormous pressure to the corresponding management of the enterprise: Data sort is various, data repeats redundant, data retrieval is difficult, the security of data and share management to wait a moment. A lot of enterprises had realized, the orderly administration that achieves information will become the crucial factor that keeps banner in prospective competition. A new administrative idea and technical PDM arise below this one setting, it is a foundation with software technology namely, it is core with the product, realize unifinication of pair of data related the product, process, resource the technology that compositive managing. PDM makes clear fixed position to create a company to face, it is administrative core with the product, it is the 3 gist white that runs message with data, process and resource. The product structure that PDM has two masterstroke of information management are a static state and dynamic products plan technological process, all news organizations and resource management spread out around products plan, this also is PDM system has do not run a system at other information, if business information runs a system (MIS) , production resource plans (MRP Ⅱ ) , project management system (natural resources of PM) , company plans (the crucial place of ERP) . The application of PDM 1. PDM of limits of PDM data management is really a kind " be in charge of very widely " software, always can change finally into the data that the computer is described and stores, it is OK entirely is in charge of, for example: Analysis of file of plot of product structure and configuration, spare parts definition and design data, CAD, engineering and data of test and verify, production plan and file of process designing of normative, NC, image file (attempt of photograph, model, scanning graph) , product manual, . PDM can apply in each industry domain widely. But the characteristic that every domain has its oneself and demand, administrative levels requirement of application and standard are not same, do not have universal PDM system to be able to include consequently. 2. PDM of PDM user object can touch every corner of contemporary company, every nerve. Inside the enterprise, as long as it is the person with product data contact with, can use PDM. 3. Of PDM and business information compositive the action that in the information of the enterprise system of the PDM in compositive process can be interpreted to be to remove a compositive frame, CAD/CAM/CAE of all sorts of applied process such as, EDA, OA, CAPP, MRP, . .
.
Etc will carry various kind, if use interface, development (enclose) etc, regard each as the object directly and by compositive come in, make must distributing in the enterprise each places, use in applying individually (move) all product data be able to height is compositive, harmonious, share, process of all product research and development is able to optimize highly or recombine. 4. The 9 big functions that the function that PDM product has can satisfy the PDM product that each respect uses the company to should be had, include structure of documentation management, job shedding and process management, product and configuration management, examine and cooperation of annotate on, scanning and image service, design retrieval and spare parts library, project management, electron, tool and " compositive " function. PDM system makes system of PDM of ISO900X with might doubled can realize the course that ISO900X place needs automatically, reduce charge and improve work efficiency. PDM can provide the tool of executive ISO900X standard to the enterprise. Product data manages (PDM) the sense that in the information that realizes an enterprise the compositive, level of management that increases a business and product develop the field such as efficiency is very tremendous, it is one of main techniques of domain of current computer application. We will introduce in succession from the back in the PDM system of collect, everybody also can connect come round to ask group interior the PDM of the homepage to column understands more content.
