The manufacturing mode of the setting manufacturing industry that nimble production 1-1 produces is in ceaseless changes and development in, the focus that competes at the beginning of 20 centuries is cost, what arise from this is the producer style that big batch dimensions changes; The focus that metaphase competes seventies is quality and integral efficiency, flexible automation production is main producer type; And the requirement of 21 centuries market is much breed, small lot has dynamic and changeful characteristic, because this is made adroitly,be considered as main manufacturing mode, putting forward the essential mind that makes adroitly is answer in order to change changeless, its are essential the characteristic is to be answered quickly. Accordingly brisk production business is had agile and changeful, answer quickly, quality is good wait for a characteristic. Put forward as what make adroitly, the whole world lifts an upsurge quickly, appeared in the United States a lot of research organizations, will study achievement application obtained result at company production. Be like: The United States overcame Hai Dehang empty company to build in the name of a river in Shaanxi and Henan provinces 1995 " the nimble infrastructure network of production system " the result that already obtained your person to fix eyes upon at present. American scientist puts forward to be made adroitly basically is the reason that is based on tripartite face. It is the development of social diversity and personification; 2 it is change of business affairs environment exceeds an enterprise to dog adjustment ability; 3 it is American IT develops quite. The computer reachs the swift and violent development of communication technology, created technical condition to be made adroitly further. The implementation that the key that 1-2 carries out makes adroitly is to adopt the computer network that uses information period and information processing technique, will distributing to establish dynamic alliance to form dummy company to have an advantage in the of all kinds enterprise of different district complementary and of implementation. The key that because this is carried out,makes adroitly is to build fictitious business namely dynamic alliance and fictitious make also say to draft real product development. The enterprise is in carry out nimble production need to take the following step: (1) enterprise interior establishs arrangement clear, compressed, right transfer to a lower level organizes means dynamicly; (2) forms open dynamic alliance and dummy company; (3) takes the person's element seriously adequately, establish it is with the person this contemporary concept; (4) stresses technical innovation; (5) organizes trends changefully, talent and new and high technology are compositive. Characteristic of nimble production technology can divide two kinds big: It is the angle implementation that organizes L structure and strategy of administrative L sale from the enterprise, 2 it is the angle implementation from the technology. Carry out the application that makes the IT of hang on of each technology lieutenant general that specific place involves adroitly. The IT development as network technology, the payoff that is manufacturing industry not only and it is the most active drive element. Because this key of nimble technology is sufficient,apply IT. The 2 IT arrival as intellectual economy times, this one element is replacing news the substance that dominant position holds in production system on the history and energy two gist element, and rise quickly to restrict the dominant element of modern production system, become the most important resource in modern manufacturing industry and the most precious competition essential factor. IT is promoting 21 centuries to make a technology develop the effect in the process is the first. The iformation flow of production system includes two big masterstroke (like the graph 1 shows) : It is the processing of product information and treatment; 2 make and adjust be manufacturing plan and administrative information. How to have technical government to these information, make production production reflects nimble sex, PDM technology has particularly important sense. Essence of technology of 3-1 of 3 PDM technology seventies, as the development of electronic technology and computer, appeared the individual automation technology such as CAD, CAPP, CAM, MRP, but ask to what change adroitly as a result of the market, these individual technology application can be in only local improvement the work efficiency of the enterprise, not can from go up at all those who change a tradition is serial working mode, because of this PDM emerge as the times require. PDM is to use government all information that concern with the product (include information of file of component information, configuration information, documentation, CAD, be authorized to wait) with all information that concern with the process (the definition that includes a course and management and be authorized and distributinging information) . The control ability of the administrative ability that it has collect database, communication ability of the network and process and an organic whole, the information exchange of activity of the group in real distributed now environment and share and undertake to designing a process trends is adjusted with monitoring, still can support well muti_function design a team work in coordination. In nimble production technology, PDM is not an onefold applied technology, contact company course data and application the information infrastructure that be together however. Because this is used with compositive the administrative frame that changes a product to develop a system. The most PDM software of city has graph archives to manage before the requirement order with contented 3-2, flow management, the basic function such as project management. The system designs the PDM that the enterprise develops to information of project of design phase of bureau be confined to manages and also cannot suit very well to make the product that leaves with fictitious environment develop the need that creates a process especially adroitly. Face the PDM that makes adroitly, return the function that should have following a few sides: (Data of PDM of 1) different compose manages, realize the confederative mechanism of PDM system; (The applied system that compositive and different environment leaves 2) ; (User management and network safety ensure 3) trends; (4) supports collateral design, offer timely communicating for different different ground user, the environment that works in coordination. Anyhow, facing the PDM compositive platform that creates adroitly should be one kind is had can reframe, but the information of put sb in a very important position and dimensions changeability is compositive platform. 3-3 studies the current situation and meaning PDM are the new technology that 80 time appear, all previous matures with each passing day via 20 old development. Be in the United States, the enterprise of nearly 50% uses PDM technology. There also are 10 old researches in our country, be applied by a lot of enterprises, obtain good economic benefits. Be like: Printing machine of Beijing north person fetterses Inc. is the enterprise that PDM of the first application in state-owned company regards compositive platform as, if case of set prescription of collect of its PDM system pursues 2, this system has the system such as CAD, CAPP, CAM enclosing, have attributive and data government to its by PDM, what realize design information thereby is compositive. Because PDM side overweight designs the management of information, the management that purchases to producing reserve passes MIS system to manage, the data structure of two systems is different, data switch can pass the form of data interface to come true. Here the environment falls, new product development changed primary product to develop the constituent way of personnel, by administrative section office (design division, technology division, standardization room) instead is an unit with the product, wait for the project group that personnel forms by design, craft, standardization. Make design craft to standardized the job such as examine and verify to break administrative organization, reduced the message between service not free. After executive PDM, cycle of new products plan shortens than before 15%-25% ; Change model because products plan is used rate is higher (can amount to 50%-80% ) , cycle shortens than before 30%-50% ; Workload reduces 70% above. Other still company of dragon of Dalian engine plant, division waits to get very good benefit after executing PDM. Of course rate of informatization of our country enterprise is not high, be in specific in executive process, the problem that still has very much deep arrangement remains at solving. If win the support of controller, form strong muti_function branch, the technology that PDM supplier offers serves, distributing executive a few measure, the element that standardizes project and person. The problem business software that 3-4 builds PDM to should notice must undertake ability satisfies the specific requirement of the enterprise 2 times developing. What building PDM because of this enterprise is compositive change a product to develop an environment to be able to involve the following issues: The respect such as the technical support that the type selecting of the type selecting PDM of 3-4-1 PDM needs the convenient sex in the price, function, application, practical, supplier to be able to be offerred considers in the round, among them the most important is the Cax application system with PDM and existing enterprise is compositive. It includes the design of PDM/CAD interface; PDM/ERP interface design; Of 3-4-2 PDM among among the technology be be in two kinds or the passes information software between a variety of software. Use the CORBA technology that is based on ORB at present more benefit at to Internet technology outspread. The data management of 3-4-3 PDM how effective, the data that manages PDM system magnanimity reliably will be a formidable task. Be based on principle of network type database compositive PDM system more accord with the demand that creates adroitly. When course of study of this foreign enterprise builds PDM, should hold to " benefit drive " principle, connection is actual, look for accurate main contradiction, if production is periodic long, quality is flabby calm, cost is advanced, cooperate to transform gain of science and technology quickly with the college for productivity, enhance pair of person with abilities groom, improve the ability of meet an emergency of the enterprise and level of management. The rapid development of the IT that 4 last words are core as computer technology reachs his to be in the wide application of manufacturing industry, IT and the confluence of production technology are making one of main way that mechanical production technology develops. The degree of IT application will decide the competitive level of manufacturing industry. Accordingly, in new economic era, the strength A that our country enterprise should increase IT to build is aimed at its key technology to strengthen research, with raising the level of our country manufacturing industry as soon as possible. In addition the PDM that implementation makes adroitly a very serious problem is what how have the company is compositive change information system and exterior market and client demand implementation to not have seam compositive, inside information system already obtained a lot of businesses of our country very tall compositive spend the automation with information to handle ability, but restrict as a result of first technology, implementation is collected automatically and cannot answer quickly to a large number of outside news at present, because this enterprise should undertake the standardization of information and information exchange a standard (the research in be like STEP) , establish open formula architecture.
