Summary: ? Admonish of garden of ⑿ orangutan bail teachs flag still dispute condyle warmths ablaze horsefly makes fertilizer of of of sole of far of plaque round lie system of?PDM) of Lang Fei can be right the effect that collateral design has a technology to prop up. Documentation management and electronic storehouse regard PDM as systematic foundation and core module, run paralell in the aircraft there is main effect in changing a design. The article is a basis with PDM Enablers, use the object-oriented method that build a model, the aircraft that put forward to be based on Enablers above all is collateral the structural model of project PDM system; Built documentation to classify the tree that browse next, analysed the relationship of electronic storehouse and documentation management both, documentation management and electronic storehouse model were built on this foundation, transitional to the condition of documentation mechanism undertook study. 1 foreword PDM (Product Data Management, product data manages) the product development group that for the aircraft collateral project steps a branch provided an information compositive work environment, development staff can visit newest product information in any phase of product lifecycle, can assure the integrality of all data and security, accordingly, PDM technology is the main technique propping up that implements collateral project. Documentation management is the fundamental module of PDM, electronic storehouse is in the core position of PDM structure, they run paralell in the aircraft there is main effect in changing a design. Traditional PDM does not have standard interface between the system, conform with international hard, restricted an aircraft data of the product in collateral design is interactive limits. PDM Enablers is OMG (Object ManagementGroup, target management group) issuance PDM international standard, it offerred port of a standard for PDM system, the purpose depends on making PDM service can be on whole crossing-over, reach operation of the each other on whole. Because this solved these problems well. PDM Enablers 1. Since 3 edition are released formally in November 2000 oneself, acquired the company such as HP, IBM, SDRC, DEC support energetically, the PDM system that designs according to Enablers in home however is very few however. The article is on the foundation that studies PDM Enablers deep, the aircraft that put forward to be based on Enablers is collateral the structural model of project PDM system; Built documentation to classify the tree that browse, analysed the relationship of electronic storehouse and documentation management both, documentation management and electronic storehouse model were built on this foundation, transitional to the condition of documentation mechanism undertook study. The 2 aircrafts that are based on Enablers are collateral the PDM Enablers that the structural model of project PDM system puts forward according to OMG place makes can normative requirement, the structural model of system of collateral project PDM is like the aircraft the graph is shown 1 times. Graph 1 aircraft is collateral the structural model attempt of project PDM system pursues medium, the symbol states module A has to module B depend on a relation infirmly, namely A should cite the service that B place provides, other symbol explains as follows: R: The function module of PDM system (Responsibility) , use administrator, organization and organization; F: The module of public professional work of PDM system (Foundation) , use at supporting the public general affairs of module of all other function in PDM system to handle; Fw: The general management of PDM system controls module (Framework) , use support, management and the PDM function module that control all other superstratum. R, F, Fw3 person the frame that closes together to make PDM system. It offers GUI interface and to module of all PDM function (include electronic storehouse) management and control, also offer the management of pair of whole systems and control. The person that divide R, F, Fw3 forms PDM system framework outside, the module of other formed another group jointly one by one module of PDM system function, frame module offers a foundation to serve for all function module. Each function module includes PDM system: D: Documentation management module (Document) ; V: View management module (Views) ; B: Source management module (Baseline) : W: Working shedding manages module (Workflow) ; P: Product structure defines module (Product) ; E: Effectiveness management module (Efectivity) ; S: Neuter data module (Step) : C: Products plan changes module (Change) : M: Production implementation module (Manufacturing) ; Co: Configuration management module (Configuration) . Graph 1 medium Dv expresses electronic storehouse. By the graph 1 knowable, documentation management module is a of PDM important function module, it is an enterprise to macroscopical management provides a function and be support all related to the product the complete information of the generation inside information and product lifecycle provides a function. In the meantime, other module, if structure of flow management, product manages,wait to also manage module with documentation closely related. Electronic storehouse is PDM in the basiccest, most the function of core, it provides support to each function module. This shows, documentation management and electronic storehouse are the other in implementing PDM system the foundation of relevant function, the stand or fall of its function affects the efficiency of whole PDM system directly. The 3 aircrafts that are based on Enablers are collateral design documentation management and electronic storehouse model 3. The classified navigation of 1 documentation and browse run paralell in the aircraft in designing a process, documentation grows with volatile speed, build for better land, use with safeguard these documentation, PDM system must offer the classified technology that goes to the lavatory quickly. Documentation presses definite pattern to classify, making of all kinds documentation is in the system is no longer desultorily, classify orderly management according to documentation however, make the description of pertinent information more intuitionistic, clearer, PDM user inquires OK and expediently, quickly and get place to need current or the technical data in the past, decrease and put an end to repeat a design, can shorten greatly thereby the time of new products plan of series product as a result. According to design of our country aircraft and the effective demand of production enterprise, the article browses documentation means cent to be two kinds: By company department (Department) static state differentiates and press project group (ProjectGroup) trends differentiates. Company department is the origanization construction of the enterprise, fluctuant and opposite lesser, the documentation tree that differentiates by company department static state is a more complete tree, it can browse those who include project documentation and day-to-day management field all sorts of documentation: Project group follows the generation of the project and arise, fluctuant and opposite bigger, the documentation tree that differentiates by project group trends organizes documentation technically in the light of the project. Organize documentation to be able to run documentation message more in the round, clearly with these two kinds of means, make the user can locate place requires documentation very quickly. If documentation classification tree pursues 2, 3 are shown. Graph 2 delimit by company department static state archives of a single cent or penny upholds a plan 3 differentiate by project group trends documentation is cultivated 3. The concern of 2 electrons storehouse and documentation management is so-called electronic storehouse (Vault) , it is the metadata that realizes mechanism of storage of some kind of specific data in PDM system (the data that manages data) library and its management system, it saves the metadata of all physical data related to the product and file, and the finger that points to physical data and file. Electronic storehouse is general by the following 3 parts composition: Run a program (applied process server) , database server, special memery block (file server) . When the file stocks electronic storehouse, produce a record in the database above all, in order to records all sorts of information of this file, wait like file name, type, size, patulous name. Stock this file substance in special memery block next, stock as associated as this file photograph electronic storehouse Id finally database record. To facilitate systematic manager undertake administrative to its, and can accelerate the rate that the file inquires, should use reasonable form to organize the physical document in special memery block. If preamble place is narrated, cent of the documentation means that browse differentiates to press company department static state and differentiate by project group trends two kinds. Delimit by company department static state archives of a single cent or penny can record all documentation in the system among them, because this can press file of physics of sectional structure organization. If the graph is shown 4 times,the file of special memery block organizes a model. Graph the file of 4 special memery block organizes a model 3. 3 documentation management and electronic storehouse model use UML to build modular tool Rational Rose2003 to build the static model of documentation management and electronic storehouse object, if pursue,5 are shown. Aircraft of this model union is collateral design application setting, the augment with undertook certain to the brief documentation management that provides in Enablers standard and electronic storehouse model and improve, so that make cooperate with,the member in project team can obtain the documentation of newest version in PDM system in time, ensured consistency of data, integrality and security. The description in PDM Enablers standard, the function of documentation management module includes to store and be read take the electronic documentation that comprises by one or more file (safe file) , dog the documentation that those PDM systems cannot manage effectively (be not safe file) . Accordingly, the documentation that PDM system place manages (express with D) it is an aggregate concept, it is the one caboodle data that point to a file or piles file gather composition, file (express with Fi, i=l, 2. .
.
) it is an element in documentation gather, express to be D={f1 with gather symbol, f2, .
.
.
} . In whole lifecycle the information related to the product is varied, the documentation type in each branches also each are not identical, include craft documentation, design documentation to wait, the type of documentation can be defined neatly by systematic manager according to need. The file presses differentiate commonly means includes: Text file, data file, graph file, form file, phonic resembling file. Having documentation and file distinguishing is the distinction of Enablers standard and other PDM system, because this understands the concept of documentation and file correctly,be the base that builds documentation management model. The aircraft is collateral the essence of the design is a lot of systemic circulation pulmonary circulation is included in the process, it is one relapses the process that iteration optimizes because this, documentation can be passed for many times in designing a process informal edit and edit formally. If the graph is shown 5 times, documentation introduced in the model advocate (version of DocumentMaster) , documentation (iteration of DocumentRevision) , documentation (what the object such as Documentlteration) will describe documentation is different edit. DocumentMaster label documentation states those are not followed documentation edits formally and informal the property that edit and changes and behavior, with composition archives of all sorts of version cite the entrance. DocumentRevision is formal castigatory version, it was enclosed those who follow documentation is informal edit (namely the modification of documentation version) and metabolic attribute and behavior. Every DocumentRevision is the one part of certain DocumentMaster. Documentlteration was enclosed those who follow documentation is informal edit (namely the modification of documentation iteration process) and metabolic attribute and behavior, it is the place that points to memory data. Every Documentlteration is the one part of a certain DocumentRevision. They are combined together with aggregate relation, can describe documentation thoroughly the metabolic process of each version. DocumentM Aster, DocumentRevision, DocumentIteration traverses indirect land of ItemMaster, ItemRevision, Itemlteration respectively again from label interface kind Identifiable is successive documentation marks (or documentation date) label of condition of as specific as some words is relevant couplet, the documentation user ability that accords with specific words condition only is classified in documentation browse in the tree. Graph the static model of 5 documentation management and electronic storehouse object pursues 3. The flow that collateral design is support information comes to the status change aircraft of 4 documentation of movement, and information is it is carrier with documentation, accordingly, the to documentation object lifecycle in PDM system is operated, reflected an aircraft the flow of collateral design. The operation that the each pace in designing a process for strict control can execute to documentation, the article defined 6 condition in the light of documentation object: Design, check is entered, examine and approve, extend, file and deserted. If the graph is shown 6 times,the corresponding change of the lifecycle operation of documentation object and its condition concerns. Graph graph of change of position of 6 documentation government pursues 6 medium " group " the concept that is a broad sense, can be professional group according to effective demand fractionize (be like: Load group, construction group) , a certain number of layers such as project group, accordingly " group electron storehouse " the layer still can undertake expanding, patulous basis can examine and approve administrative levels along with documentation how many and calm, after the file enters electronic storehouse by personal list check, documentation is in belong to advocate share inside the group that belongs to, for the group other member consults; Enter when documentation examine and approve level, after the examination of disparate arrangement of ideas is passed, extend limits shares limits to also can be decided according to examination administrative levels namely. Of course the examination with higher administrative levels, the range that its extend is bigger, extend finally in overall situation, documentation is in global electron storehouse in. The article is in 4 last words to understand the foundation of PDM Enablers standard to go up deep, began the research to documentation management and electronic storehouse model, the aircraft that put forward to be based on Enablers above all is collateral the structural model of project PDM system; Built documentation to classify the tree that browse next, analysed the relationship of electronic storehouse and documentation management both, built to be based on PDM Enablers standard on this foundation, object-oriented, the documentation of collateral design manages supportive aircraft and electronic storehouse model, transitional to the condition of documentation mechanism undertook study. The documentation management that article place offers and electronic storehouse model apply successfully already at aviation 2 groups among project of some aircraft collateral design, application makes clear, this model is feasible, effective, supported well aero design in coordination.
