Implementation Of PDM Technology In The Manufacturing Industry

With the development of market economy, enterprises face larger andlarger competition pressure. The market requires enterprises to offer betterquality, more low-cost products in shorter time. Could have met this kind ofrequirement and already become the key whether modern enterprises couldsurvive and develop. In modern enterprises, with the wide application ofcomputer technology and CAX application program, production efficiencycan be improved by a large margin. Meanwhile, the product information inenterprises demonstrates the explosive growth, have produced the newproblem. In enterprises, each department produces the product informationwith different CAX systems. These lack kind interchangeability very betweenthe product information that produce by different system, have formed"detach islands of information", it is unable to utilize them high-efficiently. Inaddition in information inquiry, useful information is flooded in the ocean ofinformation, difficult to search. Statistic indication, find out old datum 70times in design engineer, there is only 30 to create the time to design. Thereare a lot of which manage products data issues concerned , for examplefollow and design the affiliated project , guarantee to use and design the latestedition of the materials etc.. If you deal with them improperly, you willproduce the negative effect to working efficiency. So the problem ofmanagement of the product information has already become the key problemfurther improving production efficiency.The information technology has already permeated different respects ofthe society and each aspect, the use of the information technology has alreadybeen rooted in the hearts of the people. Person who make enterprise feel ,adopt information technology change to go on mode of production generallyalready, become it in the face of the most important foundation that thechallenge depends on of era for existence and development. Because thewhole of earth is becoming an organic whole under the modern technologicalmeans progressively, resources are expected to dispose in the world, anyinformation can be transmitted and finished in the twinkling of an eye, today,rely on the information technology means to innovate continuously andrespond the market fast, have already become enterprises and gained the keyof the advantage! New monobasic technology and application software mustsupport the demand for enterprise's development of economic era of the pace ,i.e.: Can combine all important business of enterprise and employ or not canhave been combined in the system sewing;Data model , data warehouse ,integrated platform of data with unity;Form , employ chain around threadthat enterprise run , support enterprise run the whole management of lifespan.Products whether enterprise depend on existing foundation, products databasic data of enterprise, it runs through all respects of enterprise's internaland external activities, is core and key of enterprise's information. Productsdataflow enterprise most key chain of information flow, can reflect enterprisewhole material , fund to manage course and flow course message directly,enterprise other information launch and exist around product informationwith shape of attribute their. So, the products data are origins of enterprise'sdata, the flow of the products data has formed the thread that enterprise'sinformation flow promptly. Manage products data and flow PDM technologyof course, among in existence all enterprise message application technology,possess become enterprise source of data and affect enterprise wholeprecondition of thread of application system better than other extanttechnology objectively.The data management of the products (PDM) is the technology ofsolving these problems. The main function of PDM system is as variousintegrated frames of computer application system, realize managing productsdata, and then achieve the goal of controlling to the production process of thewhole product. It will offer the strong tools of a piece of human resourcesutilizing enterprises to the maximum extent and information resources forenterprise.With the deepening constantly of study and application of advancedmanufacturing technology, the data management of the products (PDM)becomes the important component of enterprise's information. In the designprocess of the products, a large number of products data can be fully sharedthrough PDM, have solved the problem that between the automatic detachedislands. I refine the question with characteristic of enterprise out in PDMimplements through PDM project participated in, having carried on deeperresearch as to several items of key technology of PDM, making a briefinstruction to the content of this text below:1. Background and meaning of studying in PDM technology, domesticand international development and subject.2. Definition of PDM concept, the origin of PDM and developinghistory briefly, and concrete function module of PDM, PDM latesttechnology and development trend.3. Enterprise's standardized preparation work: Establish the system ofclassify coding. PDM is closely related to standard system fullyreflect in implementation of PDM. It is significant to do the work ofstandardizing well before enterprise's information is implemented.4. Output the method of BOM in PDM system. Various BOM play arole in contacting engineering design and technological design in theintegrated manufacture system based on PDM frame, it is essential,nearly reflect the whole lifespan of products course.5. PDM necessity, how to select PDM system, PDM implementingscheme of system and need question and PDM application of systemthat notice integrate implement, of system that system implement.Because PDM is used for enterprise's information integration,improve the great meaning in respects such as the managementlevels of enterprises and product development efficiency etc., haveenabled a lot of large and medium-sized enterprises in our countryand fully realized its application's importance. Enterprise implementPDM system to expect efficiency to improve product development ,shorten products listing time, improve enterprise fighting forstrength unexpectedly at market, but a high one success rate letenterprise and software company have , review implement methodand question that should pay attention to. So PDM employingspecifically in enterprises is paid close attention.The purpose herein is for explaining this kind of technology.Theoretically, questions met are answered while implementing PDM systemto enterprises from practice.
