1. Preface is used as new technology in great quantities, the technical state government of weaponry is more and more complex, the original technical position that is carrier with paper file manages means to already cannot get used to need. Enterprises of a lot of national defence scientific research are in the last few years to apply for national ability actively to change investment to be used at building PDM/PLM system, exploration uses IT to improve technical condition to run the way of ability. At present a lot of units had completed construction, major PDM system is already progressively main effect is produced between scientific research production. But the PDM project of a few unit is in carry out, an a few problems that deserve attention are revealed however in motion line of business. These problems basically are in centrally following a few respects, it is general devoted construction above all cost is huge, average cost is in the project that chooses foreign product 3, 4 million. Next the function of deepness of each unit construction, implementation, adoption level is uneven, cannot realize the communication between the system. The 3rd, the thimbleful function that the system of individual unit realized PDM only thinks completed PDM construction. The 4th, face the situation that breaks a function truly in great quantities, the director staff of our enterprise however muddy does not become aware like that. Without product structure the canal gives some manage function, PDM in the PDM system that the author discovers even in survey process the system sheds system of PDM of management, some to be able to manage WORD format only without the job the file be short of lose PDM system basic skill can severe case. The occurrence of these circumstances restricted PDM system badly due the play of action, bring about extensive staff to generate suspicion to popularizing the meaning of PDM system. This causes bigger negative effect to the informatization construction of enterprise of national defence scientific research. Appear such circumstance, main reason is the fraudulent action of undesirable manufacturer, get us to understand insufficient opportunity to PDM system, realized a few functions only so-called completed PDM construction. The efficiency that this shows to we lack a scientific and effective PDM/PLM system evaluates a standard. For this, while we plan to combine 206 product data to manage a system to build, undertake PDM system efficiency evaluates technical research, data of work out product manages (PDM) systematic efficiency evaluates a standard. Facilitating superior makes an on-the-spot investigation, the moving efficiency that evaluates system of each unit PDM, judge this ability to revise the result of investment then, improve for follow-up investment point out direction. Stop the baleful action of undesirable manufacturer, protective ability changes investment, make PDM system is producing effect really. 2.

This covers standard construction the standard is not to be used at researching the market not specificly the actor bad of product of a certain PDM, however with the system in already some real data are a basis, from the system the function goes to the lavatory twice with moving effect will measure those who criticize system of PDM/PLM of a certain unit to run efficiency surely. It will by a series of carry out easily, exercisable test inscribes composition, each test subject incorporates title and grading regulation. The PDMPLM system that tests a title to will enclothe industry to think generally is main function, namely structure of electronic storehouse, product, job shedding, configuration, change and the system is compositive wait. And project management and cost control whether to belong to PDM/PLM must function, industry still has different controversy, name a person for a particular job of these open to question function do not undertake grading temporarily. PLM and PDM system photograph are compared basically is the administrative idea that raises complete lifecycle, the technical position that increased particular product example to be being made and safeguard period namely runs a course. We will weave in the light of this part special test is inscribed technically, each unit is chosen according to his circumstance. Moving effect respect will from use easily, data is shown, authority and true use wait for a respect to make an on-the-spot investigation. Total test cent is 110 minutes, systematic function respect occupies 90 minutes, moving effect occupies 10 minutes, PLM function is add 10 minutes. The key evaluates content to be as follows: (1) . Electronic storehouse and graph documentation management inspect electronic storehouse to whether press kind of physics of product model, file classification and classification of file management type will distinguish organization. Inspect electronic storehouse to whether have the administrative ability to standard component. Inspect document of administrative script content (WORD, WPS) , graphical file (AUOTCAD, PROTEL) , three-dimensional model (PR/E, UG) , the table is simple (structured data) the ability that waits for type data with emulation data. Three-dimensional design is inevitable trend, can utmost ground is close to true condition, OK and distinct the earth's surface amounts to all geometry that gives stylist to conceive. Accurate three-dimensional model can bear intensity analysis, motion analysis, assemble interference analysis, machinability analysis and modelling effect evaluation. But difficulty of three-dimensional model management is ambitious at other type file, put in complex and associated character among them (between spare parts and component associated, between model and project attempt associated) . Because of this management to three-dimensional model the evaluation of ability and the associated ability that pursue with 2 dimension project divides a value to will hold greater weight. (2) . Product structure researchs a system the descriptive ability to product structure, a component used what component, and by what component place is used, and to it what does close and associated file have. Product structure whether be adjusted, adjust a process controlled. Whether divisional a component experienced level of what development experiment. (3) . The data object that working shedding inspects place management (wait like model, blueprint) whether accordingly mark marks its located lifecycle condition, can be the scope of application according to certain data and attributive with this. Make an on-the-spot investigation to whether the job sorts the data object such as a model, blueprint ordinal the desktop that sends the member that appoint work, undertake checkup by this employee, appraise sth through discussion and circle are red. The system adjusts data object according to examining a result (file, blueprint) lifecycle condition. (4) . Configuration inspects the undertakes product put sb in a very important position and combination are changed capacity of PDM system, inspect its whether use number of existing and effective design to configure combination according to agile, apace, will satisfy the requirement of the user, achieve reduce cost, shorten plan and the purpose that improve quality. (5) . Change research a system carrying out change what whether the provision passed among the process to examine approval process; The member that whether to weave and use a person of the use person to the file that be changed and associated documentation gives out what the description changes detail to change an announcement; And change executive result to whether can limit the scope that changing announcement description compulsively finally inside; Whether can the condition that all previous of file of electron of inquiry, understanding changes; The index attribute of electronic file should be mixed of text change whether keep consistent; The electronic file after answer with the paper file that outputs before and be being changed whether keep consistent. (5) . The system is compositive inspect PDM system and business (CPC/ERP/MES) system, other PDM system and the compositive ability of all sorts of editor tools. For example PDM is one of company application systems, do not answer to build independent identity attestation function again, and should undertake with what the enterprise unites attestation mechanism compositive, ability makes sure user information is between each application system effectively deliver. PDM system should be in all sorts of editor tools (PRO/E, WORD) compositive operation menu, convenient employee is used. PDM system should mix other applying system (craft, goods and materials, other PDM) build compositive port, realize data deliver; PDM system is due with experience foundation data (yuan parts of an apparatus, offer square, section) synchronous ability, carry consistency of data. (What 6) runs the effect to research PDM system is actual moving effect, whether is judgement PDM system used truly rise, keep whether for a long time daily a certain quantity of entry number. Research PDM system whether authoritative, paper file happens abhorrent when, whether be with electronic file fiducial. Whether to put electronic document to use branch or personnel hair directly. Research a system even whether safe, must have the mechanism of prevention and cure of corresponding attributive control, virus and time equipment cent. Whether is the system used easily, the requirement that can use a department according to the data such as craft, goods and materials, production and quality develops product data. (7) . The main distinction of PLM function PLM and PDM depends on having the capacity that complete lifecycle manages, PDM basically covers design phase, the data that its manage is unit with making batch at most, there is how many product without giving thought to in every batch, its design data is same. PLM should enclothe the whole lifecycle of the product, in make and maintaining a course, the metropolis of every product has difference, maintenance, debug and quality data can differ. Systematic government data is with the stage second be unit, data bulk will be great a lot of. 3. The standard basically is evaluated paragraphic evaluate a project to check a method to divide storehouse of value grading electron and graph documentation to manage 20 minutes as a result with the evaluation of 206 systems whether does storehouse structure press product model divisional data lists the overall product data of some model 22 whether according to, check its whether did sort of 22 government data manage literal content file in the use circumstance in the product from the electron find among storehouse, the file that opens the format such as a WORD or WPS, and their historical version 22 whether to manage file of planar project graph from the electron find among storehouse, the project attempt file that opens an AutoCad format, and their historical version 11 whether to manage an electron to design format file from the electron find among storehouse, the circuit that opens the format such as a PROTEL designs blueprint, and their historical version 10 whether to manage three-dimensional model file from the electron find among storehouse, the three-dimensional model that opens the format such as a PR/E, UG, and their historical version 22 whether to manage watch sheet (structured data) from the electron find among storehouse, open a watch to be occupied oddly, and their historical version 10 whether to manage emulation data from the electron find among storehouse, model of 10 three-dimensional models and project blueprint open the data of the input that opens the emulation software such as a NASTRN, ANSYS, output blueprint of a piece of project, observation design, modification model, open a project to pursue again, see a pattern whether synchronous change. 22 component model and spare parts model open model of a component, observation included what part among them, model of modification spare parts, open package model view to check again, see whether synchronous change. 22 products structure structure of 20 minutes of products whether the entire component that finds out a component to include? The entire component that lists a component is included 33 whether judge a component to at what be used package? List at what a component has been used ministry package 33 whether find out 0, all file that place of ministry, component manages? List 33 edition instinct denies all file of correlation of a component find out 0, of ministry, component evolve into a process? 33 component version and the relation of use spare parts add the complete edition that lists a component evolves one stature component, whether does superstratum component version increase the relation of version of 33 spare partses and referenced documentation to increase documentation of a management, 33 jobs shed the process that spare parts version increases the 22 version that adjust what already released component to adjust whether controlled listed certain to release component formally already to adjust 10 minutes to count the lifecycle that occupies an object to whether have lifecycle to list some data object is experienced 22 jobs flow whether drive, whether is the circle red? Examination some job flows examine whether see of purpose and the circle is red 21 whether processing is waited for after signing personnel to check flow to start from hillock problem whether change sign personnel 21 outside unit staff whether participate in sign list staff of an unit outside having participates in signed document, find the evidence that agrees to sign. 20 configuration 10 minutes whether form product configuration? The linkage sex that 55 products configure the entire component that lists configuration of at least two kinds of products is included and associated file and designs information alters somewhere design, above the examination whether does the place design follow among two configuration change. 55 change 20 minutes whether undertake controlled change? Of the document that listed some portion has altered examine the person that whether do 44 examinations have flow to be used to original document to give out what the description changes detail to change an announcement whether do 44 examinations have measure change executive result to whether restrict the 33 inquiry inside the range that changing announcement description, understanding; The index attribute of 33 electrons file should be mixed of text change keep consistent. The electronic file after answer and be being changed holds the paper file that whether 31 test and verify have a method to assure to output consistent. 31 systems are compositive attestation of portion of 10 spare time from one's main work to attend to sth else checks some in whether after use personnel leaves his post, needing to run a system in human affairs only, be handled and do not need to have government in PDM system 22 with the tool compositive test and verify is in those who have PDM system in some tool software, OK and direct check is entered, check goes out 22 with other data (craft, goods and materials) compositive test and verify is other system (craft, goods and materials) can read directly take PDM data 21 foundations data yuan it is parts of an apparatus, OK to wait for data for square, branch guide from other system directly. 21 with other PDM system object of data of some of compositive test and verify can enter number of other PDM system and version to have clear corresponding concern. 10 minutes of daily entry person-time figure 21 moving results and user number is dailier than the system judge all log onto a number / systematic user > 0.

Whether do 331 have paper file to sign complete file to be printed exclusively by data branch in collateral test and verify, the file that print is absent in returning stylist hand. 33.

Whether to extend outward unit sends electronic document electronic file, do not send paper document. The stock detailed list that 21 data show listed some product 11 component statistic lists some kind of typical component is in the medium quantitative 11PLM function of many products is add some of every test and verify is specific the administrative ability of the product inquires to already made work from inside selling a record the number that gives a product, it is clew to list in PDM system with this number the product structure of this product, and the number of crucial component. 52 listed above the maintenance log of example product, and the subscription of this record flow. 52 CNC Milling CNC Machining
