Product data management is one is a foundation with IT, it is core with the product, compositive the technology of the information related to administrative institute travel and product and process. The article elaborated the executive setting of PDM, pass an analysis medium or small the development existing state of affairs of manufacturing industry and the possibility that admit a trend to elaborate executive PDM and necessity; Proved the executive process of the project, on the base that undertakes to the enterprise demand wither grinds, carry out appropriate the client changes PDM system, introduced the executive method of this system and executive key technology: Summed up the benefit that the project brings and the issue that need to solve. One, the executive setting development as market economy, the enterprise is facing greater and greater competition pressure. The market asks the enterprise offers the product of better quality, lower cost with shorter time, whether satisfy this kind of requirement to already became contemporary company whether the key that live and develops. The ceaseless development that uses as contemporary computer technology and the leap of global network develop, IT opens brand-new one page for traditional product manufacturing industry, make design and make the directional progress that faces high grade, efficient, low cost of the product. Medium or small the common characteristic of manufacturing industry is product breed much, batch is small. The user is different, the demand is diverse also, expand of dimensions to expand with the abidance of scope of operations ceaselessly as the enterprise, data is shared, repeated usage and each information isolate each other the contradiction between is apparent with each passing day. The main problem that exists normally has: (1) is not shared as a result of what design information, fortune often becomes the knowledge of the enterprise to be kept by the individual; Of personnel, post fluctuant, bring about product blueprint to lose; Because be not shared, cause easily repeat, missing, omit and wrong hidden trouble. (The file data of 2) paper medium brings about pair of file data to inquire difficulty because of the reason such as careless omission, mistake, affect the efficiency of the design. (3) information is not shared bring about processes of pair of research and development to cannot undertake seasonable understanding and effective monitoring. In the development process of new product, the inquiry with director staff continuous need just can understand the progress situation of the project. (4) designs a process to control inadequacy to the change of the product, easy create a design data is promiscuous, uncontrollable to changing incidence. Blueprint is new of old version divisional reach misapplication to wait, will produce negative effect to work efficiency. (Because 5) designs a branch to not be clear that the stock of purchase department lays in a circumstance, can bring about cannot make full use of to already had stock when the design, accelerate capital to be on the move; Do not communicate between design and production, outside designing personnel to be reached to state of the finished product of component, semi-manufactured goods, buy, the information of cooperation part is ambiguous, the repetition when also can creating products plan newspaper stuff is waited a moment. (Because leader of 6) financial personnel, relevant director waits for information control to design, stock not comprehensive, lack the effective control of pair of company cost, management state thereby. Accordingly, how to use the product data information of each branches as a whole, enhance the interchangeability between data information, efficient correlation uses each " information Gu island " already became us the problem that urgent need solves. Additional, development staff is being arranged, search dog the time that data spent them to make an appointment with 70 ％ , the time that is used at the design truly has 30% only about. Afore-mentioned problems of these existence and the contradictory urgent need between a variety of demands that the company grows are a foundation one kind with IT, it is with the product core, compositive with management all information related to the product are mixed the technology of the process, the company relevant resource is moved effectively and apply rise, and one product data manages PDM systematic criterion can be very good realize this one demand. 2, the problem that the project carries out the existence in reaching executive process (one) provider of affirmatory PDM software, system of software of PDM of basic framework of program business PDM is a kind of public data shares platform substantially, the user is pressed related the enterprise need to realize each job through platform, leave a mark (a kind of visit, memory or the record) that change the operation place such as data to stay. The administrative technological process as a result of every enterprise each are not identical, answer to be a foundation with current PDM software so, recombine asks severally and the characteristic has company application model 2 development. Be aimed at this one characteristic, must undertake to all sorts of PDM products survey, analysis is mixed quite, the PDM product with right make choice of. (2) the problem of the characteristic that project of the constituent structure that establishs PDM project to carry out working party to be aimed at an enterprise, PDM carries out and existence, establish special PDM project to implement a working group. (3) overall planning is in executive PDM system when. Mature the difficulty to the system and complex degree, should make " overall planning, cent pace is carried out, smooth glide is crossed " executive principle, abide by " take a side with the line " executive strategy, the project plans to be carried out in installment. The PDM system fact of whole industry is general cent period undertakes. Project first phase, nod to cut with basic documentation and BOM management (BOM: Bill Of Material -- management of stock detailed account, indicate product component, part till the relation between raw material, and the quantitative) of the each subordinate part that every assembly parts place needs, build product database, the design that realizes product data in branch of product research and development extends, of product data change extend wait for flow management; Project 2 period, the PDM(product data that is core with product data runs a system) the system is a foundation, undertake to products plan in implementation virtual administrative prerequisite falls, by the design data is delayed to production data enlarge, system of compositive on the foundation of first phase CAPP, the application that enlarges PDM system manages range, form a product to manage platform from the unified data that designs treatment, the dependability of management of the security that the confidential sex that strengthens product data, data stores, the order in which editions are printed. (4) the solid almsgiver of first phase of executive goal of first phase project should have representative product to be around pilot spread out, project group passes in-depth to PDM system survey, analysis discussion, raised the executive target of the project finally: Establish the standard that enterprise electron information shares, standard; The information that establishs safety visits a model, tool of compositive 2 dimension, three-dimensional plot, file data, concentration manages; Establish a standard, the data that the electron converts is examined and approve with change technological process; What implementation and creation tool have nothing to do is visible browse, make a circle round one's name on a document submitted for approval to show that one has read it, simplify the visit of information; Old know exactly about sth occupies guide, those who support the technical file such as original blueprint, craft is flowing and migratory; Electron of the classification that builds component and graph documentation, configuration changes frame, form the company knowledge base that uses easily. (5) of executive phase of executive process first phase differentiate. Safeguard an engineer to undertake to member of project working group the major of proper time grooms by PDM product above all, after the understanding with have proper in the concept to PDM system and principle and understanding, project working group makes a detailed work plan, press the executive demand of PDM standard, the whole executive cycle of the project cent becomes 3 main executive stage. The first phase: Survey and collect information of firm relevant department and data, build enterprise PDM to manage frame and flow to provide data data for compose. The survey of actual to departmental door condition, demand analyses the premise that is enterprise executive PDM and important basis. Project group reachs relevant business unit to develop user survey work to technical ministry, production ministry, manage from soft hardware environment, origanization construction, project respectively, compositive, version administers control of the category of data structure, documentation, active flow that sign careful, attributive, port, change demand of the regulation of mechanism, encode, management that print, forms for reporting statistics, craft to standardized the respect such as the requirement to undertake detailed survey, formed much survey data, also be the important basis that the 2nd phase carries out at the same time. The 2nd phase: Flow of work of certain business PDM reachs the working detail of each module, PDM of form cost company runs a system. According to a series of data that survey forms and information, project group begins a system to design the job, arrange, the data that in extracting survey, obtains, the physical model that begins to begin to design company future circuit, logic is unit, form the systematic rudiment of company future. The design data of PDM manages working flow to pursue as follows: From the product data management flow chart can see foundation and a few decisive module is -- the definition of group of kinds of the product is old management, user, put in storage that put a figure. The first, kinds the product is old manage. Have the product kind that reachs future to may be added newly, different specifications, model to undertake the effective classification of the product by the enterprise, the product structure tree that forms clear palpability is the fundamental premise that improves product management efficiency and method. Also be the base that reflects whole PDM efficiency. Pass the couple with user group module, can control different user to be restricted to the visit of different product and access. The 2nd, have the definition of user group. By product management the requirement undertakes corresponding user group is defined, certain personnel runs a model. Press different product type to will design personnel to be divided into corresponding drawing office, every groups of member that set group leader, group reach affirmatory and respective subordinating relation. After user constituent matchs, by member duty division of labor differs allocate corresponding attributive, type PDM system to form the control of attributive through user name and password. The blueprint with different attributive corresponding correspondence is browsed, change, download, print wait for an operation, proper user attributive management is the security that assures product data data, the foundation of accuracy, integrality and consistency. The 3rd, put graph put in storage. The ability after the product plan that design personnel completes stocks PDM database correctly only forms the data source of PDM. Show level to load tool of plot of 2 dimension CAD, the three-dimensional software such as PRO ／ E, Solidworks can be received after be in, farther promotion designs sectional invention. Besides new design the product needs to put graph put in storage outside, already will have historical product group by group put in storage, press for different user need to extract information to provide data source from PDM. The 3rd phase: Environment of this custom-built and unified enterprise CAD plot, provide n/arc drafting platform of the standard for technical cartography. will already typical product data is arranged through the standard, batch guides PDM system. The data origin that PDM system manages is particular product, the BOM data structure that forms by a series of blueprint place is cultivated. The spare parts that can inquire every component place is used conveniently accordingly, also can inquire every spare parts or component are used on which a few components or product, can generate list of package of spare parts schedule chart, ministry to wait by different pattern. Follow-up and all stock, outside buy, outside assist, using the extraction that waits for information all is with this amount to seizes a base. To achieve the goal that the project carries out, must data of normative design fountainhead, the CAD that the demand that presses PDM software standard makes our company below plot environment makes environment of chart level, cartography, normative stock (component, material, bought-in component, standard component) norms of name, encode, model, style of column of the picture frame of normative design blueprint, caption, detail column. 3, benefit is analysed in breed of a product the company with much, small batch carries out PDM, brought benefit and change are very apparent. (One) immediate beneficial result the first, accelerate taste newly appear on the market speed, shorten the product appears on the market periodic. "Accelerate taste newly appear on the market speed, shorten the product appears on the market periodic " mean an enterprise to be able to grab preoccupy market, score additional gain. Will tell to the development of the enterprise, occupational the market is OK the market share with larger seek, win pair of market dominant places further. The 2nd, stimulative design put sb in a very important position, reduce product cost. PDM regards business information as compositive platform of the system, those who promoted iformation flow is expedite, the repeated usage of company product knowledge got simplifying further -- the process that designs new product can consult conveniently original products plan experience, reduced research and development and trial-produce cost. The 3rd, ensure product quality and product service. Through building a business unified, whole information platform and strict flow restrain management, the product that reduced mistake to cause discards as useless, duplicate the job and spare part, improve product quality. (2) the informatization management concept that indirect benefit promotes entire company; The science that is a leader is decision-making provide support; Establish company image, accumulate an enterprise aeriform knowledge fortune. 4, executive experience the first, the attention that the enterprise leads and support make to implementing project begin crucial; The 2nd, when undertaking overall structural frame designs the system, must consider the real case of the enterprise, want to have certain flexibility, in order to get used to the adjustment of business flow and the adjustment that the enterprise organizes a structure; The 3rd, the PDM product that the advantage has on choice technology and service and service business are very main; The 4th, active constituent management is the assurance that PDM carries out successfully; The 5th, make clear overall objective, level target, schedule of regular examination work and finish rectify and reform a circumstance; The 6th, the use that the quality of Training Within Industry such as the manager of the controller of the enterprise, system, person that use commonly will affect a system directly and safeguard; The 7th, the PDM system of the enterprise is main by him enterprise personnel will safeguard and undertake 2 times developing, it is very important to participate in development to work as soon as possible; The 8th, dog the newest condition that the technology develops, adjust relevant development direction of the system in time, perfect PDM system ceaselessly.
