The computer is compositive one of main techniques of production domain - - PDM

Growth of G00 PDM market is very rapid, according to CIMdata 1995 year those who release is right PDM was investigated 1994, PDM market was about 1994 4.

7.8 billion dollar, predict to be able to amount to 1.6 billion dollar 1999. PDM market so rapid growth, it is the demand because of the market, at present already more and more company businesses realise use PDM comes the organization, value that access and manages design and development to reach production data. Use PDM technology can shorten the time that the product appears on the market, lower the price of the product, improve the quality of the product. The times that this technology is competing now, increase the capacity of meet an emergency of the product, enormous beneficial result produces in market competition for the enterprise. 2, PDM of PDM basic idea is the technology that is a foundation with software, it mixes all message related to the product all processes that concern with the product are compositive together. The information that the product concerns includes any data that belong to a product, detailed list of the file that is like CAD/CAE/CAM, material (state of cost of form of order of configuration of BOM) , product, transaction file, product, electron, production, supplier. The order that all processes such as guideline of the treatment process that the process that the product concerns includes any concerning, treatment and relation of concerned approval, access, safe, duty standard and method, work flow, orgnaization handle. It included each fields of product lifecycle, PDM can make newest data applies to concern an user entirely, include a project to design staff, numerical control machine tool operates personnel, money to meet personnel and salesperson can press the access with convenient requirement to use concerned data. According to Summit Source Consulting " VPSCii guideline " what describe, CPSCii is the alias of PDM, it is by the abbreviate of Vault, Process, Structure and Configuration Management/Change Control, "i" of among them two the ordinary form of a Chinese numeral represents Interface and Integration. According to this kind of description, PDM is like next relevant term to define: Electronic Vault namely electronic database. Vault most normally application is "Vault is offerred generate, memory, look up, control is accessed, restore, the ability " of examination of editor, electron and the history that record electronic object and general file. Process or Process Control namely process or process control. The form that it sheds to any jobs undertakes the process is controlled, or the mission control after the process begins. It provided the action of incident of course, drive, electronic examination, history, look up, access control, restore the editor with the object. Crossing the basic ability that programmed control restricts is a definition process, attemper and electronic task. Structure namely structure. If the user has memory and the capacity that dominate many electron news, so, maintaining the relationship between different message Duan Zhi is very important. This to some object also be particularly important. The product provided link an object arrives the ability of another object. This kind of object is description of VPSCii construction part. The structure allows to generate, name, the edits one-to-one relationship and control to be based on a relation object of navigation and multistage. This kind of ability is the product structure that can create through one or more company normally of implementation. Configuration Management/Change Control configures management namely / change control. Except simple relation, a lot of companies are adopted offer simple structural ability to dominate more complete product data by the product. These companies want to control is configured and change control, they must make strong relation control. Configuration management / change control was offerred generate, management, navigation and editor are man-to-man the relation with a pair many. They also are offerred mix with relation information look up access pilot ability. Interface namely interface. Without doubt, want successful implementation PDM, the tradition that transforms a company with respect to need manages mode and traditional culture, the enterprise should make these changes, with respect to need new field weaves way. The application of user interface, because these changes and new field knit the effect that means place causes,can decrease apparently. Integration namely compositive. Compositive it is to maintain the many module of VP-SCii to be stuck cheek by jowl together, it also uses relevant other at the tool of VPSCii is stuck cheek by jowl together. Include operating system, service platform, client platform, DBMS, compositive with development tool and additional applying etc. Interface and Integration are not the component of PDM itself. But, they are crucial to the promotion application of PDM. So, a good PDM software product included electronic database, process or process control, structure, configuration management / change control, interface and compositive wait for a few parts to comprise. Can see from afore-mentioned introductions, PDM is serve as whole with whole industry, can span group of whole project technology, it is to make what the product is developed quickly and business course changes quickly make can implement. Additional, it still can go up in the network of distributed industry pattern, with other application the system builds the main tool of direct connection. PDM can be organized, the commercial industry news that access and dominates a company to concern. Its limits includes resource configuration, production to make, planned dispatching, purchase each respect such as development of sale, market, consider all issues from whole production industry for whole.
