The basic principle of PDM software function and type selecting

Electronic storage function (Engineering Document Of Vault) it is PDM most the module of core, by storehouse of information of Information Ware- House() with supervisor of warehouse of information of Information Warehouse Manager() two parts composition. It dominates environment and the outer world for PDM (user and applied system) the data between passes the measure that provides a kind of security. A completely distributed electron storehouse can allow an user not to have the product information of enterprise of the visit that seam the ground quickly, and the physical position that need not consider user and data. The function of this one module includes: -- the check of the file is entered and check goes out; -- search a mechanism by attribute; -- trends browses ／ navigation ability; -- storehouse of distributed electron of ／ of distributed file management; -- security mechanism. 2.

Working shedding or process management function (Workflow Or Process Management) it is the method that uses definition and control to people is founded and revise data, main management occupies the meeting when undertaking operating what to produce when an user logarithm. The activity of all general affairs and data dogs inside the data flow between person and person and the lifecycle in a project. The automatic management that develops a process for the product offerred this one module to assure, support what company product develops a process to recombine in order to obtain the biggest economic benefits. It basically has function of the following respects: -- the job that face the task or be inserted temporarily and changes flows; -- the structured job of regular drive flows; -- trigger, remind and call the police; -- email interface; -- the graph changes the job to shed a design. 3.

Configuration management function (Management) configures management with electronic storehouse (Vault) supports for ground floor, with material detailed list (BOM) organizes core for its, rise all project data that defines end item and documentation connection, achieve the organization of product data, control and administration, the different view that lays to offer product structure to user or applied system in stated goal or regular tie and description (As-designde, as, Assembly, as-manufacturing, a9, imI! The) such as Ed. It is simple version control and material detailed list not just found. This part function is as follows: -- of material detailed list found; -- the control of version; -- search of supportive Wher Used; -- as compositive as MRP; -- support regular drive configuration. 4.

Examine with function of make a circle round one's name on a document submitted for approval to show that one has read it this module examines and approve check out procedure to provide technical support for the computer. The data content that the user can use it to examine electronic storehouse to store (especially image and graphical data) . If need, the user still can use a graph to enclothe a technology to have punctuate and explanatory note to the file. It has the function of the following respects: -- those who support a variety of standard format files examine, include PDES/ ／ STEP, IGES, DXF, DWG, TIFF, CCIT, Postscrept, HP GL; -- the CAD system with current and popular support (wait like Autocad, Pro Engineering) to file of text system type examine; -- enclothe with red line punctuate or graph; -- support tripartite software examine. Because differ at present,software business lacks unified consistency test on the implementation of standard format file, those who bring about different application system to ask is same kind of standard format file is incompatible, accordingly, if possible sentence, use as far as possible by the application that makes this file the system examines this document, such ability eliminate the potential error that brings by afore-mentioned abhorrent sexes. 5.

Scan and become like the function this module finishs a blueprint or microfilm scanning changeover becomes digitlization image and the control system of its park PDM manages under. What develop in PDM is inchoate, form of to in an attempt to reframes to be mixed for central scanning the foundation that resembling a system is system of management of most technology data. But in current PDM system, this part function is the very small auxiliary sex subclass in the four fundamental operations of arithmetic only, and as the computer the promotion in the enterprise applies, it will become more and more not important, because be in before long in the future, almost all documentation will exist with the form of digitlization. 6.

The retrieval of the design and design of any of function of spare parts library are the crystallization that designs personnel wisdom, the design of accumulate over a long period is money of enterprise huge intelligence as a result, using pair of existing designs to undertake innovatory creating giving better product is a when the company grows important facet. PDM design retrieves and function of spare parts library uses existing design to found new product to provide support afresh to the greastest extent namely, its are main the function includes: -- interface of spare parts database; -- be based on content is not the retrieval that is based on classification; -- the function of filter of encode of attribute of tectonic electron storehouse.

Project management function so far, project management considers less in PDM system, a lot of PDN systems can offer the job to spread state information of the activity only. A very strong project government implement the state information that can provide minutely project and activity for controller, through PDM and popular project government software is wrapped (the report ability of the program that if interface of Microsoft Project, Artemis) is returned,can win resource and important way. 8.

Cooperation of electron of electronic cooperation function basically comes true ground of high speed, real time is alternant between person and PDM data function, the relatively good electronic cooperation technology such as the online operation when including a design to examine, electronics conference can be not had seam the ground and DPM system to work together, allow to visit PDM boy or girl friend interactively, the issuance that uses CORBA or OLE information and sign a mechanism to combine PDM object cheek by jowl rise. 9.

Tool and " compositive " the government that the data that information and correspondence can share to arise with systematic place between the applied system that the function differs to can make has unity, must exterior application system " enclose " in PDM system, can move below PDM environment. Enclose those who involve regulation to differentiate and of the data type of corresponding generation differentiate, the means that the condition when also stipulating applied system moves at the same time and data of applied system generation store automatically in PDM. The function of this module has: -- batch processing language; -- apply interface (API) ; -- ability of process designing of client of graphical interface ／ : -- system / ability of object process designing: -- the tool encloses ability; -- compositive (example is compositive, the product turns application compositive, be based on regulation compositive a) . 2, the type selecting of software of basic principle PDM of PDM software type selecting is to carry out one of PDM important and decision-making, it should follow the following and basic principle: 1.

The function spends a function is the function that shows software place comes true and the degree that satisfy user requirement. The system of company level PDM with powerful function should provide some pivotal character and its tool and the service that should provide to have: (1) main item -- object-oriented structure, make its have the strongest join concern between data. -- modular structure, so that press,need to expand. -- current figure interface, if Visual Basic is used on the OSF ／ Motif on workstation, Windows PC, convenient user, stimulative application. -- the product structure editor with powerful function, if CAD ／ CAM is mixed,be united in wedlock cheek by jowl between MRP, BOM. -- have extensive company course to control capacity, if work flow arrangement, sign reach careful to approve extend, wait according to the visit according to function size logarithm. -- include a variety of incident, system that start and function inside the product that is based on regulation. -- the table electron equipment of alterable dimensions, access to a purpose of individual and company level easily. -- agile compositive application kit ／ API, so that enclose,mix compositive software program. -- the process designing tool that uses easily, change its system to support executive demand with the user. -- the PDM option that has group class, can conveniently the augment application to whole industry level. -- integrated systematic management software, in order to build product and process resource model. -- distributed database environment, with optimizing resource is mixed increase performance. -- function of quality data change, so that use proper form data consign user. -- accord with all sorts of standard requirements in the round, be like ISO900, CALS, CITIS, MIL-STD, PDES, STEP, IGES, SDAI, CORBA, FDA, the demand of OSHA and appropriative user and government to this respect. -- ability of much place communication, communication is carried out inside limits of alive bound. -- support uses heterogeneous machine, achieve the goal that accesses data with lowermost cost thereby. For example, supportable UNID(and VMS workstation, PC, Macintosh, large scale computer the client computer that wait. (2) extra item -- the service that improves proposal and visit to environment of whole product development reachs his to diagnose a tool. -- the system is compositive with executive expertise, also call a domain expertise, run paralell for example the support of the project. -- system and the skill that run a side serve, the technical operation that includes workstation, server, central processor, operating system, application software and network software to wait among them defends a service.

Practical practical it is the ability that shows PDM software satisfies actual project to ask, particular system now: (1) flexibility: The flexible rate that each function module deploys PDM software, namely whether do each module provide contented user neatly the combination of the module of specific requirement. (2) uses a sex easily: The convenient degree of the friendly degree of the user interface of PDM software and operation, wait like graphical interface, help, tutorial. (3) dimensions sex: The suitable scope of PDM software, include project group class, enterprise form. The PDM system of project group class faces design team, be aimed at project of specific research and development, basically be compositive content with 9 kinds of application software, use dimensions is controlled to 100 in a few, move in environment of sth resembling a net of local area network. System of company level PDM can comprise much chance to plant with aleatoric dimensions by user demand, much network environment, majority occupies much library, more distributed Server much application crosses the enterprise, large system that is apart from an area compositively together, offer the complete solution that is based on collateral project idea for the enterprise. (4) can visit a gender: PDM software visits the ability of data in time quickly. 3.

Opening a gender to open a gender is the open ability of architecture of software of M pointing to the fourth of the twelve Earthly Branches, provide. Body reflects in: (1) independent character: PDM software is independent the ability at hardware, operating system, network, database. (2) user influences ability: The 2 development capacity of PDM product, include to use environment of process designing interface, development and tool. (3) collect by nature: PDM software uses a system with other (like CAPP of ／ of CAD ／ CAM, word processing, MRP) compositive ability. 4.

The maintenance that the technology supports ability technology to support ability to include software product, version upgrades, the problem such as technical support. With MRP software photograph similar, PDM is a software not just, more important is it offerred mode of a kind of business management, this characteristic decided the value that the technology supports. PDM software has a process that suits each other with the management of the enterprise, this needs long-term, good technical support. 5.

Executive case and technology of successful experience PDM are technology of a software not just, and also be an executive technology, have stronger practicality. A executive case and successful experience are project success important assure, rich successful experience can reduce executive risk. 6.

Economy economy is to show the premise that asks in contented user falls, answer to so that save investment,choose low-cost PDM software as far as possible, choose the software system that function of optimal value ／ compares namely. 3, analysis of function of PDM popular software is current, although the supplier of many Europe joins PDM software procession in succession, but main international supplier still is in North America. The PDM software product of main now popularity has the following kinds: IMAN, Metaphase, Optegra, AutoManager, Workcenter. The function analysis of software of these a few kinds of PDM sees subordinate list. CNC Milling
