Dig PDM potential deep, promote a product level of management in the round

In the upsurge of manufacturing industry informatization of like a raging fire, emerge in large numbers gave technology of a lot of heat. Among them, with PDM (data of product of Product Data Management manages) the technical informatization that give priority to shows driving demand in manufacturing industry enterprise, it is the main component of solution of whole of manufacturing industry informatization. As each individual technology and integral market established practice delimit water rises smoothly, PDM system is sure to become enterprise informatization to build the main platform that prop up. Because the actual application effect of this PDM technology also will is opposite,project of informatization of whole manufacturing industry produces far-reaching effect. One, its apply the burgeoning technology characteristic that the 4 phase foundation that PDM technology uses appears in the development process of IT and PDM function can differentiate for 4 phase, (the graph is shown 1 times) the progressively promotion that reflected PDM skill adequately. Product figure documentation manages the main application target that developing earlier PDM is the memory that solves many electron data and administrative issue, offerred on the foundation of large database " electronic data storehouse " function, the orderly file that realized product data basically, safe visit reachs the function such as version management, executive effect is better. But the PDM system that this phase appears basically faces blueprint paper, its architecture and provide function are simple, the collect by nature with other system is poorer. The configuration of product data and compositive management this phase uses object-oriented process designing method on software technology, make a program modular rate rises greatly. Additionally the attention object of PDM also rises to product data by original documentation, the new function such as the management of product structure and configuration management, compositive, job shedding with CAX/ERP, version management is ceaseless emerge in large numbers, accordingly PDM product moves toward maturity from academic system, commercial respect, specializationed PDM provider appeared on the market. The project government idea with the process advanced management that is based on a project becomes current business to pursue target-seeking heat technology increasingly, because this PDM introduced " project management " function. PDM system turns into to manage in real time by management of former after the event, the process control that pays close attention to project development, work in coordination, added PDM to the enterprise " hematopoiesis " function. But mechanism of this kind of job also is existing a few defect: ▲ task is finished, after project group is disbanded, follow-up technology is improved, the product safeguards the job to often be lacked successional, when product development becomes group of project of short-term action ▲ to establish often preferential choose seasoned engineer, the education that pair of new employee changed infirmly on certain level works, as a result of,the talent that goes against whole department is fostered in small and medium sized business original constituent setting and working mode, mechanism of project group work did not get overall situation is popularized. Only project management is in academic system is as aspirant as executive method one pace is perfect, what ability makes sure PDM is in an enterprise is comprehensive carry out obtain favorable result. Extend further on the base that the complete lifecycle of company level runs depth to apply this phase to manage in product data, introduced be based on three-dimensional the fluctuation that can inspect a technology swims supply catenary to cooperate with product business affairs, namely PLM solution. From the product data management is jumped rise to manage for knowledge, applied limits enlarges final user and partner from enterprise interior. the design of the product information enters production to make a system directly, purchase with what supply catenary to go up, production, sale and business affairs are compositive rise, build a platform of unified system of product research and development. 4 phase showed PDM skill the process of successive development, also reflected a business the process of synchronous to PDM demand heighten. Pass level differentiate can help enterprise recognize located phase and executive key, to establish PDM application target is having very good direct effect. 2, analysis of level current situation and applied emphasis are at present current the be confined to of administrative levels bureau that development of system of most enterprise PDM applies the 2nd phase, better land achieved the orderly administration to product data, but the standard of product research and development that did not form significant step to increase a business to the product is configured and compositive managing, from go up at all the core competition ability that enhances a business. The product management job of the enterprise is backward, what basically be engaged in product data and standard is custodial, distribute wait for routine management job, science of the seriation that lacks essential sex, generalization plans. Specific issue highlights style now: The uses relation disorder to create a company product structure arrangement of component is various, because the history accedes,the component between series product uses a relationship become unusually complex. In the design process of series product, existing the component with a lot of good versatility, design of dimension of its specifications, structure is more reasonable, because this is in the remodel design of range of products,naturally is come down by continue to use, because its pursue,date, name all was not altered, the need that stems from manufacturing organization call his " grafting part " . As the grow in quantity of series product, this kind uses a relationship complex with each passing day also, a lot of component are lent refinance, former even subject product already no longer current; Some product model grafting part occupy 70% above, make the job such as organization of the order processing of the enterprise, production, product management caused data disorder, it is very difficult to cause traditional handiwork to maintain product structure. The data disorder that because this wants improvement,is faced with must do good foundation data arrange, the program works. Be based on modular the product configuration function that devises an idea did not get developing original product structure adequately complex and lack scientific program, caused the structure between each assembly, component to differentiate ambiguous, match parameter unsharpness wait for a lot of problem. What manage effectively because of lack at the same time is complex use a relationship, did not fashion tangible product basic structure model. Because this also created a product,differentiate between module ambiguous, the idea that modular, generalization devises is couldn't get carry out, rise in what design and level of management restricted on certain level. Be in for example much breed small lot " order " cycle of processing of the order in the enterprise is long, the plan that give out often short of is best, its prime cause is lacked in the product standard that forms at original order " digitlization model " , design personnel basically relies on experience processing, lack strong tool support. And type of this kind of production asks to design personnel to be found in the shortest time there already was a product like the photograph most, undertake according to order on this foundation remodel is designed acceding, avoid to redesign on the oldest rate " new part " . The product management strength that can see major company through the analysis of above insufficient, administrative levels is unhappy not greatly, newlier, the order for goods that restricted a product greatly is formed of fast processing, seriation in order. Raise the put sb in a very important position of original product to lead, those who improve a product is modular design a level, the product in becoming PDM manages the focal problem that module solves, and how to limit with the grafting part in managing a product, general part it is the first issue that needs to solve. 3, the significant step that deepens application builds complete company general part, standard component library to go out to be used in the statistic on the foundation of model of whole product structure the component redefine that the frequency achieves X second above is general part, according to general part encode regulation builds complete company general part library, corresponding ground establishs standard component warehouse. The encode of general part is regular should the subordinating relation encode with original slam the door, and use code of classification of characteristics. Make full use of build in PDM " digitlization model " , through be being checked instead to grafting part, general part, know the number that be used at any time, use the position. In addition through powerful maintenance, retrieve a function to be offerred to design staff compositive the component government tool that share, make design, plan, supply, the branch such as production can seasonable, comprehensive ground masters pertinent information. The definition regulation of standard of specific company product passes product statistic function in but the basis designs medium general part new product standard can apply after the amount reachs certain level, the definition is series of standard or basic set, it is company product standard via evaluating late cloth strictly, decide specific product structure model. The likeness that when new order is handled, can ask according to the technology spends the range of products with corresponding make choice of, add on this foundation decrease component to come rapid remodel design satisfies client need. Raised the rate of put sb in a very important position of the product thereby, improved level of management of product generalization, seriation. Perfect product configures a concept, development application is modular the thought of the design does by total division, the design of function branch organization such as product management division or standardization room, craft, supply, the branch such as plan, production, sale, customer service center sets out to consider product structure module integratedly to differentiate from respective working angle, series, form the product module that accords with market demand and enterprise interior to run a requirement to deploy sheet. Then adjusts original product do not accord with in the structure modular notional part, for modular the design lays good foundation. Define each module then between match relation and corresponding and crucial parameter, final implementation product configures a function, improve a product modular design level. 4, the product component that uses benefit to look into average company composes scale (like the graph 2 are shown) , standard component and bought-in component achieve 45%~55% , and general part and likeness occupy 30%~40% , the component that needs special design and treatment occupies 8%~15% about. And special component occupied 65%~75% however in place cost cost (like the graph 3 are shown) , this part component accordingly change is general part or standard component is produced to reducing taste cost to having all in all effect. According to the executive experience of software theory and certain and advanced company, the development that adopts a system carries out the generalization level that is sure to improve company product, market competition ability that enhances a product. Analyse from the current situation above, the strategy that improved the respect such as measure to elaborate near future PDM to improve actual application, the effective demand that joins a company can make PDM produces bigger beneficial result certainly, to improving the market of the enterprise competitive ability has tremendous stimulative effect.
