The article manages to product lifecycle (PLM) in executive importance undertook treatise, put forward to implement the concept of process and content, showed the program of PLM system and analytic method, explain understands the executive methodology of PLM. 20 centuries since 90 time, as the flying development of science and technology and world economic integration, and the people pressing requirement to zoology environmental protection, manufacturing industry is facing new challenge. Winning the market and contented user demand is the focus that the company pays close attention to. Accordingly, shorten the development cycle of new product, government target that raises the quality of the product to become a company. PLM (product lifecycle manages) the formation of original concept up to now, the generation setting to PLM, function and applied benefit had had people to know. Carry out in PLM on, some closer year come to a few companies of home also hope to be carried out to PLM in succession undertake discussing with research, the hope can sum up those who give to accord with Chinese national condition to carry out train of thought. Go up objectively say, in domestic PLM carry out still be in start level, "Carry out " this concept itself still cannot be accepted extensively by the society quite, about PLM executive major seeks advice to be lacked quite, professional executive team is little little, make thereby of PLM carry out smoothly got very big limitation. The enterprise is system of the information that finish carry out, adoption measure is retain office of 4 big accountant " foreign " seek advice, but often took change with this locality not of conform to " natural environment refuses to obey " problem. One, carry out the PLM with significant position famous whole world is held to sought advice from company CIMdata to was released in July 2003 in PLM " PLM market analysed a report 2002 " . The idea that mentioned core turnover among them -- core turnover is safeguarded by software and software and carry out a service to be comprised jointly. Core turnover indicated the integral actual strength of an enterprise and growth. Graph 1 before was being represented 10 PLM technology supplier is in the portion in this market category. From the graph 1 in see not hard, EDS and IBM+DS obtained apparent turnover from inside executive service, occupy core turnover about 2/3 the left and right sides. The service orgnaization that every main integrated supplier continues to develop them uses these orgnaizations to create additional, persistent turnover flows. Visible, carrying out the success to PLM to advance is very important. Graph 1 2002 the core of supplier of technology of year ago 10 PLM year turnover (ordinate: 1 million dollars) at present, advance as enterprise informatization energetically, the enterprise of domestic executive ERP is increasing. In last few years, although home has had the project of many PLM, but basic upper limit runs a system at the project data of Technical Division, compare with photograph of executive ERP system, manage innovation without what introduce materiality; Additional, of a lot of CAD or CAM software advanced mode to affect the idea that the enterprise pushs to PLM now greatly, the enterprise thinks, purchase software of a PLM, can be in an enterprise to advance like CAD, when PLM type selecting, often special the function that cares about PLM software, and ignored " carry out " importance. We think, PLM software just provided platform of a software or information compositive frame and corresponding tool, want to build a practical PLM to run a system for the enterprise, still need to do a lot of businesses, namely what normally we say carried out. 2, organic ground joins the staff member of the product data information that the executive process of the executive PLM system that meets PLM project is an advanced software platform, enterprise and enterprise rise, according to advanced management thought and administrative method build a truly economic technology news to run a system for the enterprise, satisfy the need of the enterprise thereby. The content that PLM carries out is very extensive -- the effective demand that should join a company will decide all sorts of government targets and its attribute and conjunction concern; The working flow peace conference of certain personnel signs flow; The BOM list that certain business place needs and the format of all sorts of collect forms for reporting statistics; The PLM of custom-built enterprise manages structure and administrative pattern. Should vigorously the enterprise already documentation of some many electron data, blueprint undertakes standardization arrange, proofread, examination, in inputting PLM system correctly next, go. Want various to the enterprise administrator and technical personnel to undertake skill of PLM overall thought, management and operation use a method groom, make they can use this system adroitly to have routine, it is good to defend management normal, safe, stability runs this system, truly implementation enterprise manages to the whole journey of product data. 3, need accurately systematic program and analytic industry must beforehand the PLM with clear protocol implements an aim -- the criterion that this matters to PLM to carry out not only and jumping-off place, more the reference point that matters to PLM to carry out and examine standard. The PLM with clear tie carries out target and product development existing state of affairs, what the product development that the enterprise should understand a product to develop PLM of the influence in the process to carry out a target to come true involves system of working flow, application and relevant data. The working technological process that involves to use PLM to develop place to the product undertakes administrative, the working flow that the enterprise must manage to wanting to undertake above all has explicit definition and description, certain work flow is basic composition, amount, crucial link and basic structure. Pass working flow analysis, will be helpful for an enterprise recombining, determine the main demand of PLM system, still be helpful for controlling executive limits and timeline at the same time. Data storage and management are the basic function that PLM place provides, and the foundation that is other function. But the correlation differ in thousands ways between the data format as a result of the enterprise, type and data, need to undertake many client chemical industry is made when using PLM to undertake administrative to its, have analysis and definition to the data type of the enterprise and correlation ahead of schedule, raise corresponding special requirement, it is a when choose PLM software important level. Also provide necessary referenced basis to control the executive rate of progress planned speed of PLM at the same time. Those who use system and other business or manufacturing system is compositive a be influence PLM executive success important segment. The system is compositive must can undertake administrative to showing methodical bequeath data, can realize information to share between each systems again at the same time, reduce number to maintain the integrality of data according to be being mixed redundantly. However, the system is compositive it is a very formidable job, it asks to carry out personnel to understand PLM software and applied system very. Different and compositive spent requirement, if enclose, applied interface arrives finish compositive, the time that needs to expend, manpower and charge will have apparent difference. Normally, if there is mature interface between PLM software and applied system. Aux will be able to assures the plan that implement effectively. Accordingly, before software of PLM of choose and buy, must analyse existing applied system condition and compositive pattern. Let dress in light of us the PLM system program of plant of car of Qi Haer railroad, can get from which beneficial, precious edificatory. Carry to get used to freightage of 21 centuries railroad fast inevitable trend, this factory decides development gets used to product of two kinds of of new condition new-style van: Rapid movement box wagon and bay grain car, achievement of technology of PLM overall technology and its key is used in deciding in these two kinds the design of new product is developed. Establish by the design personnel, cold (hot) the new product that technologist, production personnel comprises develops a group, will quicken a product to develop a process with this, force contention completes the development of these two kinds of products 1 year to time of two years partly. For this, neat factory did many thorough and meticulous executive organization to work, undertook ① establishs executive group, ② personnel, responsibility and mission layer upon layer fulfil, ③ factory and carry out advisory company to frequent communication, ④ grooms extensively and groom centrally the documentation standard that photograph union, ⑤ built system of neat factory PLM, ⑥ built a product to develop group, ⑦ . 4, the experience that PLM carries out the unit that carries out PLM successfully without shortcut to reach from inside practice is: Press executive need group of an executive core, its member should accept adequate training, so that disseminate the information of the respect such as concerned technology, benefit, problem effectively; Should have affirmatory cause and should clarify why must be like,bring PLM. How should the far seeing plan of the enterprise achieve these goals clearly; Cost / benefit analysis should be finished; Systematic demand wants to decide; Choose software finally and begin to undertake executive. Carrying out is the practice of a kind of technology below methodology and engineering experience guidance. Usually, can encounter following problems more or less: 1. Meeting those who encounter traditional habit restrict PLM is a technology only anything but decision-making. Since PLM is the technology of a kind of management, so the element of person and company system must consider. The improvement of working flow is the impetus that PLM carries out apparently, but the change of flow is not easy thing definitely. The working habit that changes people to be formed for a long time often brings quite big workload to the enterprise, time of the huge in causing PLM to carry out thereby is protracted. The decision improves working flow and the necessity that how let employee approbate often PLM is carried out in most the thing that expends energy. Below most circumstance, people is used to completing their work with some kind of means, often regard ego as the medium that development, ego protects with this; Because a lot of cadres built his career or profit on original flow and be willing to maintain the current situation more; Some employee also may stem from the consideration of the interest of the enterprise to hold to old some system to destroy the change of flow not self-consciously thereby; At the same time the person of each estate worries about his rice bowl or official position. Above these problems, industry leader should have sufficient thought preparation, grant when carry out at the consideration. 2. Should choose reasonable PLM to although PLM has a variety of functions,carry out methodology, can help an enterprise realize the harmony between collateral job, much branch, shorten of the product appear on the market time, but differ as a result of the actual condition of the enterprise, the specific target of company application PLM also differs very big. In PLM software executive project, of the control of the process of the project, quality assure, technical consign and the problem that managing the effectiveness that flow recombines often is their care, professional executive methodology is the effective method that the satisfaction that solve these problems and assures a client spends. Through old practice, ERP executive methodology is already mature, same, a complete PLM is carried out also need to logical executive methodology undertakes guidance, and should carry out methodology to should have following characteristic: (1) deploy of the carries out product of the systematic program before including to carry out, PLM option that covers executive lifecycle PLM, PLM and try move, PLM tries move evaluate, PLM is carried out in the round, the phase such as the maintenance of PLM system. Accordingly, a complete executive methodology must can cover each executive phase. It can coach the client analyses the requirement that understands oneself and the aim that implement, the phase that reasonable arrangement carries out, undertake appraisal of organization of funds and quality control, personnel, achievement wait. Logical methodology is the summary of PLM executive experience normally. It should include all PLM to carry out place must important segment, avoid a client to undertake those who explore type carry out thereby, assure assuring plan. (2) comprehensive quality management PLM carries out cycle longer, and the working cross correlation of each phase, the plan that because how this assures the executive quality of each phase,will affect whole executive work and entire constitution are measured. Accordingly, reasonable executive method will have complete technical documentation, can coach the user understands the working content of each phase on one hand, facilitate again at the same time undertake effective quality is controlled. Crucial link must install quality to control test point, put an end to before detecting through quality, undertake leaving the job of one phase. Through this kind overall quality is controlled, the problem that is helpful for reducing schedule of whole executive work and quality, reduce executive cost, quick implementation invests redound. (3) executive methodology should help the PLM with the good acceptance that pays close attention to an user the client decides and come true above all " the owner that the client is PLM project, PLM supplier, representative or the partner that advisory company is a client " idea. In executive process, can assure to undertake to client or final user PLM software and relevant and academic knowledge engraft. Strengthen their understanding to PLM technology and support. On the other hand, should establish include user, supplier to reach its representative or the executive team of relevant advisory team, the plan that implements certainly satisfies their requirement. Executive crucial link must be decided by the user and undertake checking and accept to carrying out the content of plan and quality. The acceptance of final user and use, it is the basic composition element that PLM carries out a success, also be the basic the golden rule that PLM implements a success. (4) the Know-how technology that contains rich experience and Know-how technology PLM to carry out methodology to include rich industry experience and key. Know-how is the high concise of knowledge, wisdom, experience and skill, be a technology have value most reflect. The Know-how technology that implements a method about PLM is rare more. Outstanding executive methodology can help an enterprise be when program PLM project, avoid to consider technical element or sectional factor only, and oversight the integral requirement of the enterprise; Ensure the enterprise is below limited investment, assure to invest the quality of rationality and project; Avoid a lot of errors and risk thereby.
