Contemporary in making distributed design in coordination

Summary: ? Border of establish of new moon of exacting of core of  of ü  path calls frequency of   bail to suckle an ancient nationality in China scrupulously and respectfully eight of  of Qiong of ⑹ stool ┨ washs with watercolors K of vinegar of С idol border must provide dinner for hold border of establish of sincere busy Mu calls fat of black of  garden saute  ⒄ of Mu of frequency of   bail stalk  , suit for development " the whole world is made " products plan develops a technology -- distributed design in coordination laid a foundation. Distributed the part that designs the inadequacy that overcame existence of traditional CAD technology in coordination, answer product of market research and development quickly for the enterprise, offerred new thinking and technology. Distributed design in coordination (Distributed Collaborative Design, abbreviation DCD) is the collective environment that shows through network technology tectonic collaboration is designed, work in coordination in different ground in the process, obtain all sorts of design resource (include to design staff of tool of material, design, design) optimize configuration and long-range resource to share, in order to finish collective job. Distributed design in coordination also can call many bits of cooperation to design (Multilocation Collaborative Design) , the computer supports design in coordination (Computer-Supported Collaborative Design) , or abbreviation to cooperate with ground of design, different is designed etc. Distributed devise the new method that regards a kind of product as research and development in coordination, its purpose is to develop the core advantage of the enterprise and core resource better, the resource that realizes each enterprise is shared and the advantage is complementary, handle the challenge of the market jointly, participate in international competition jointly, grasp market opportunity better. It overcame what the tradition devises a method to close of gender, limitation and design ability imperfectly quality, the repetition that reduced design resource is devoted, shortened product research and development is periodic, the competitive ability that enhanced a business and market develop power. Distributed design in coordination the design the method brings new level, developed the new field that devises theory. 1 distributed devise example example in coordination 1 it is the model that has successfully cooperating with designing. The Boeing that Boeing company invests 40 much development 777 planes, be coordinate this company to be in the branch of world each district and Japan dispersedly by network technology 5 companies such as heavy industry of 3 water chestnut are designed in coordination with what make. The Boeing company engineer of alive bound each district at any time Ke Congbo sound 777 planes the v in many 300 component among them a kind, right on computer screen observation of three-dimensional model component, research, revise. Boeing the development of 777 planes, begin to be designed from October 1990 test-fly succeeded in June 1994, use 3 years of 8 months time only. Exemple 2 it is American department of defense entrust Caspian university to organize many 100 company to consider to write " the strategy of 21 centuries production enterprise " the tentative idea plan of the report. Uited Comm is the dummy company that produces electronic product, it is will dispersed the electronic group that in American each district the of thousands of employee of many 60 company contacts together. The employee of company itself has a few people only. Dummy company relies on design of network technology mix, production, management substance, the partner is dynamic, in order to get used to different product development, improve, make, the need that sell and serves. The company presses user demand big batch custom-built production all sorts of complex electron products. Money is offerred inside 24 hours after the design assures to receive order with modern production technology in coordination. 2 distributed the characteristic that designs in coordination is seen by example, process of the member composition that designs in coordination, development and its system environment and traditional CAD have very big different. Is expression in: ? Establish border calls   bail shoot a glance at a bit the allied organization that baric grandma an ancient nationality in China quarrels Lan box? participates in a design (the member company that designs in coordination namely or organization) the likelihood distributings in the whole nation even world each district. : of sex of effectiveness for a given period of time? The organization that Lian of bad ┤ Wo vases? of cut of Zhan of R of Sui of San of illicit of mulberry   participates in alliance (enterprise) can combine by area or industry, also can take no account of completely regional or industry sex influence. They are run commonly in different operating system and database environment, the company culture of allied enterprise and administrative pattern are different also. Complementary sex: ?  of Wo bing4 ru4 gao1huang1 says Cong of provide for of some a bit our zinc grabs graceful cough of archives of ㄒ of  of acetic round brilliant to protect  commission  Xin of Qiong of Bao of postscript of bell of children's hair of mother of bail riverside instrument sends faint of У of travel of  of sword of chasm of palpitate of Huan of a drum used in the army in ancient China enlighten to Song Biao approach cough our  washs with watercolors, each alliance organization cooperates inside allied limits, and in other sphere may be a competitor. Distributed is the characteristic that designs a product to develop a process in coordination distributed devise a method in coordination the complete lifecycle: of perforative product? Song of  of midge of a surname of ⑹ of two of pilfer of ぱ of  of Jia of full a short wooden stake of ⑹ of idle of Tao of Man of garden of ⒅ of Pi of bail of Tuo of border of ⒓ of Pi of Gan Biao of paddle of ⒎ of Pi of the bail that pat ruthenium takes 2  flying bail to cast aside emperor to steal large bamboo hat of bad natrium of closely question ヒ censure  of to joke of  of  school  , exchange of the information when solid reality and share. The mode of product development process is serial with collateral reticulate mixture structure. Distributed the characteristic that designs a system in coordination is structural frame with the communication technology of Internet/Intranet, implementation designs the each service function in the system. It is different compose condition next distributed, open mode and compositive the environment of work of much user CAD that change, also be the client that is based on Internet/Intranet at the same time / the CAD system of server architecture. Can realize data of compose of much view, different to share. Use standard interface, if the data such as IGES, VRML, STEP exchanges a standard, so that CAD information is shared. Provide the conference tool that support negotiates interactively, if real time is three-dimensional conference of video, frequency, e=mail. These tools can make assist the author spans district limitation, communicate design idea at any time, discussion problem, complete long-range and alternant design. Can undertake operation of long-range and fictitious emulation model and dynamic observation, trends is added note and revise text and international standard view to decorate etc. Can establish the flow control mechanism of based Internet/Intranet. 3 distributed the executive condition that designs in coordination falls in Internet/Intranet environment, resource is effective related personnel of the product ground of distributinging Yu Yi, design and enterprise the ground is compositive rise, realize long-range resource to share, have form of different ground different distributed design in coordination, need to establish the cooperative trends alliance between the enterprise above all (call dummy company) again. According to the informatization degree of enterprise oneself, the cooperative administrative levels between the enterprise can be divided for low, medium, tall three-layer. The arrangement of ideas that cooperates between the enterprise is disparate, adoption technical method and method also have very big different. The Internet network tool that the low administrative levels between the enterprise cooperates to basically wait for convention through E-mail undertakes simple logo and data are exchanged. Information exchange volume is little. Between the enterprise in the collaboration of high administrative levels, need itself to have taller informatization degree and modern level of management above all. Have oneself Web server and network resource system commonly. Product information can be browsed directly with Web between the member that different ground designs, uses CAD/CAE/CAM system and PDM system are based on network environment. This kind in the support that the collaboration between the enterprise of high administrative levels needs a lot of relevant technologies, if ground of database of technology of distributed network news report, network, different cooperates with,work the information that real estate of technology, different tastes exchanges a technology to wait. 4 distributed the development of the network technology such as the Internet of technology of network of the technology that prop up that designs in coordination, Intranet, WWW makes information transmits the network of different ground to become reality with data visit. Web offerred cost of a kind of support the network with low, good user interface visits medium, offerred reliable information carrier to trends is built alliedly. Pass the extension of pair of HTML languages and Http agreement, make Internet environment supports electronic figure browse, in making its make design process, undertake information delivers the convenience tool with communication. Allied member uses network technology to join effectively together, share resource, improved the work efficiency of allied enterprise and quality greatly. Net of aether of full duplex operation and 100Mb/s aether net are conveying in time in coordination information field still is put in inadequacy. FDDI(is fiber-optic distributinging data interface) , Asynchronous Transfer Model) of ATM(asynchronous transmission mode, fictitious network the union of 3 kinds of technologies, improve data effectively to transmit, the memory problem of network bandwidth and dynamic information, it is distributed in be being designed in coordination at present relatively effective network technology. The CAD technology support of CAD and environment of multimedia technology network is distributed design in coordination. All sorts of software were offerred turn CAD tool to three-dimensional parameter from attempt of 2 dimension project, accelerated design rate greatly. In the meantime, of CAD and CAM close together or without seam join, came true to design with production unifinication, make product development has competition ability more. Work to cooperate with better in distributed design, multimedia technology is indispensable. Design a working group in coordination in in, the troop that ordering differently dispersedly member can use multimedia environment found, analysis and operation are same a task. In initiative phase, group of multimedia technology help member communicate an idea, offer initiative program quickly. In designing a process, can understand the progress situation of the task at any time through multimedia interface, and can go to the lavatory exchange information intuitionisticly. The those convey not easily with the character message between the member that multimedia technology returns the troop inside OK and deferent working group even, convey to hint briefly for example or speak, transmit delicate expression or signal, still can pass video, acoustic frequency and animation image to see a result intuitionisticly. The development of technology of distributed network database is network database technology to trends is built alliedly and run the support with was offerred important. All sorts of the market demand investigation that the product should include not only in the database, requires design data, and include those who build the person that choose to awaiting when dynamic alliance to evaluate data, and trends is opposite in allied moving process of each allied members attend what behave with collaboration actually to evaluate data. In the meantime, the network presses information of data of memory of system of compositive distributinging frame. the compositive information of related goods development, design memory is in public data center, consolidate harmonious, management, allow many users to deposit the data in different physics position in different spot visit. Through public data center the accredit of allied to each group realizes this. The knowledge base is the main component of network database. Of the complex issue that technology of network knowledge base can realize domain knowledge seek solution, evaluate and suggest, and can undertake intelligent inference effectively, auxiliary build dynamic alliance, what and coordinate act voice alliance is actual move, regard the expert in designing a process as the system, to distributed design in coordination provide reliable intellective support. Different ground works in coordination the technology is in proper time (the some phase in the lifecycle that develops like the product) , certain space (distributing the allied organization that is in different ground or enterprise) inside, use Internet/Intranet alliance organization to be able to share knowledge and information, avoid not the potential contradiction that sex of photograph be in harmony poses. In the meantime, in process of collateral product development, each are reached between the group in coordination muti_function in the group between each expert, the difference as a result of respective purpose, setting and domain knowledge level may bring about the generation of conflict, because this needs to work through cooperating with, use all sorts of multimedia to cooperate with tool. If BBS, electron is white board, Netmeeting in coordination the tool resolves each square contradiction, conflict, achieve finally consistent. The need is much information between allied organization is delivered and exchange. When undertaking information of different ground product is exchanged, besides deferent and in good condition product model, often still need to convey local the model after revising. Special in the products plan in close together coupling, information exchange produces at any time more. If convey complete model, need to spend a large number of time and charge, can use the design feature that is based on product component to collect information commonly, by the regulation the format is changed, reentry linage is defeated as it is said. Will revise information function at the same time at corresponding model, real time replaces products plan. Standardize a technology with compositive the communication that is fundamental design to cannot leave message with the network, premise is to have uniform communication standard. Current, each enterprises mutual in designing a process in coordination lack uniform standard, this is designed in coordination to be being carried out between the enterprise cause very big restrict. Make because of what this standardizes organize to alliance (or enterprise) build very necessary. Need is aimed at the circumstance of every allied member, establish reasonable, appropriate standard, make the collaboration between each members more harmonious, make resource is able to develop adequately. Enterprise of 5 conclusion our country develops a respect to still be put in a lot of inadequacy in the product. Main show innovates in products plan little, development cycle is long, medium and small businesses this side issue is more outstanding. Below this kind of circumstance, the enterprise presses area or the industry chooses a partner independently, use network technology, realize long-range resource to share, have form of different ground different distributed design in coordination, the product that is a kind of achieve greater that accords with Chinese national condition develops idea. DCD technology can help an enterprise break through area and the restriction that have resource of talent, material, information, improve products plan quality effectively, shorten design development cycle, quickly occupational domestic and international market: Pass dynamic alliance, make produce, learn, grind each by " close " turn into " open " , by " big and complete " change direction " small and only " , by " repeat simply " turn be Gao Shuiping " optimize combination " . Develop the research of DCD technology and application quickly, the informatization of the enterprise, modern to promoting our country, increase the competitive capacity after entering WTO, will have academic and direct import and applied perspective.
