Not only the information revolution causes peoples thought idea, the life style change, moreover has caused the production method and the manufacture philosophy huge change, may say in the recent ten years proposed the new manufacture philosophy cannot leave the support which the information technology provides, take the informatization technique of manufacture is causing the manufacturing industry as representatives advanced technique of manufacture to be in the important historical transformation time. For many years, our countrys comprehensive national strength unceasingly has strengthened, enters the pass in namely, the market competition is extremely intense, the domestic market transformed from the seller market as the buyers market, moreover is becoming the international market rapidly a part, many large and middle scale enterprises are at the disadvantageous position in the competition, even goes bankrupt, goes out of business. This article unifies our country national condition, through the analysis modern integration manufacture system and the advanced technique of manufacture relations, elaborated our country modern integration manufacture system technical constitution and the development strategy and the way, hoped makes a beneficial exploration for our country manufacturing industry development. The modern integration manufacture system meaning and the localization Modern integration manufacture system (Contemporary Integrated Manufacturing System) is the computer integration manufacture system recent development phase, in the inheritance computer integration manufacture system outstanding achievement foundation, it absorbs in the advanced technique of manufacture unceasingly the related thought essence, from the information integration, the process integration integrates the direction to the enterprise to develop rapidly, is at the core position in the advanced technique of manufacture. To be specific, it the traditional technique of manufacture and the modern information technology, the management technology, the automated technology, the systems engineering technology carries on the organic union, causes the enterprise product in the entire life cycle through the computer technology the related organization, the management, the management and the technical organic integration and the optimized movement, realizes the informationization, the intellectualization, the integration in the enterprise product entire life cycle optimizes, achieved the product goes on the market quickly, serves, the quality superiorly, the cost low goal, then enhances the enterprise the flexibility, the toughness and the agility, causes the enterprise to be in an impregnable position in the intense market competition. Looked from the integrated angle that, the early computer integration manufacture system stresses on the information integration, but the modern integration manufacture system integrated concept all had the enormous expansion in the breadth and the depth, has also realized in the enterprise product entire life cycle each kind of service process whole optimization besides the information integration, namely the process integration, and develops between the enterprise superiority supplementary enterprises integrated stage. The modern integration manufacture system technical constitution Advanced technique of manufacture (AMT-Advanced Manufacturing Technology) took a proper noun does not have one until now explicitly, the consistent recognition definition. Through to its connotation and the characteristic research, at present the common understanding is: The advanced technique of manufacture is the tradition technique of manufacture unceasingly absorbs aspect and so on machinery, electron, information, material, energy and modern management achievements, and applies its synthesis in the product design, the manufacture, the examination, the management, sales, the use, the service manufacture entire process, realizes, highly effective, the low consumption high quality, clean, the nimble production, and obtains the ideal technical economic effect the technique of manufacture always to call it has the following some characteristics: Transforms from the traditional order working to the multi-tasking way, reduces the action cycle, improves the work quality; From defers to the function division department the fixed organization form to the dynamic independent management group working transformation. In the advanced technique of manufacture, the modern integration manufacture system in the absorption computer integration manufacture system outstanding achievement foundation, continues to impel the parallel projects, the hypothesized manufacture, the agile manufacture and the dynamic alliance research work carries on thoroughly, and absorbs in the advanced technique of manufacture unceasingly the success experience and the advanced thought, carries on them the promoted application, from this causes the modern integration manufacture system to become the advanced technique of manufacture the core, the concrete explanation is as follows: 1st, parallel projects (CE-Concurrent Engineering): The parallel projects is the integration, parallel designs the product and the correlation process (including manufacture process and support process) the system approach.It requests the product development personnel in to form from the very beginning on the consideration product entire life cycle in from the concept to product abandonment all factors, including quality, cost, progress plan and user request. In order to achieve the parallel goal, must establish integrates highly principal-mode, realizes the different department personnels joint operation through it; In order to achieve the product one time designs successfully, reduces the relapse, it has applied the simulation technology in many parts; The principal-mode establishment, the partial simulation application and so on all contains in the hypothesized technique of manufacture, may say the parallel projects the development has created the condition for the hypothesized technique of manufacture birth, the hypothesized technique of manufacture will be take the parallel projects as the foundation, the parallel projects further development is the hypothesized technique of manufacture. At the same time, the parallel projects is under technical support and so on the CAD, CAM, CAPP, originally separately will carry on work in time and space overlapping, overlapping, has used the original technology fully, and has absorbed the current rapid development computer technology, the networking outstanding achievement, will cause it to become in the advanced technique of manufacture the foundation.2nd, hypothesized manufacture (VM-Virtual Manufacturing): The hypothesized manufacture use information technology, the simulation technology, the computer technology to in the reality manufacture person, the thing, the information and the manufacture process carry on the comprehensive simulation, discovered in the manufacture possibly appears the question, takes the preventive measure before the product actual production, thus achieved the product disposable makes successfully, achieved reduces cost, the reduction product development cycle, enhancement product competitive power goal At present, the hypothesized technique of manufacture already in overseas had the application, for example: American Boneing a corporate design VS-X hypothesized airplane, the available hard helmet monitor and the data glove carry on the observation and the control, causes the Aircraft Design personnel to observe the Aircraft Design personally the result, and to its outward appearance, the internal structure and the operational performance carries on the inspection; The domestic research just started, mainly concentrated in three aspects (1) Product hypothesized design technology: Mainly includes the hypothesized product to develop the platform, the hypothesized test, the hypothesized assembly as well as the engine bed, the mold hypothesized design realization and so on.Qinghua University developed the platform using American Country Instrument Companys Labview to realize the phase locking circuit hypothesized (2) Product hypothesized technique of manufacture Mainly to include the material hot-working craft simulation, the processing process simulation, the plate formation simulation, the mold manufacture simulation and so on. North the navigation the sheet formation software which developed with OPTRIS already is basic with steam can simulate the similar vehicle door the medium complex degree automobile cover and other ramming formation ramming formation process; (3) Hypothesized manufacture system Mainly includes the hypothesized technique of manufacture the architecture, the technical support, the development strategy and so on. May see from above elaboration the domestic and foreign research horizontal disparity is very big, moreover because the hypothesized technique of manufacture not only is the parallel projects development direction also is the agile manufacture core, this decided we must by it take the modern integration manufacture system the central technology, leads the correlation technology research work march, and causes them to coordinate develops smoothly.3rd, agile manufacture (AM-Agile Manufacturing): The agile manufacture is take the competitive power and creditworthiness as a foundation, chooses the collaborator to form the hypothesized company, the division of labor and cooperation, joint effort for the identical goal strengthens the whole competitive ability, makes the rapid reaction to the user demand, satisfies the user the need. In order to achieve fast strain capacity, the hypothesized enterprises establishment is the key technologies, its core is the hypothesized technique of manufacture, namely the agile manufacture is take the hypothesized technique of manufacture as the foundation.The agile manufacture is the modern integration manufacture system develops the way that must be taken from the information integration which integrates to the enterprise, its level of development has represented the modern integration manufacture system level of development, is the modern integration manufacture system development direction.4th, green manufacture (GM-Green Manufacturing): The green manufacture is an overall evaluation environmental effect and the resources efficiency modern manufacture pattern, its goal is causes the product from the design, the manufacture, the packing, the transportation, to use to in the entire product life cycle which discards, to environment influence (negative) smallest, the resources use efficiency is highest. Green manufacture statement was the people takes the environmental protection day by day the inevitably choice, develops cannot take the environmental pollution as the price, the international manufacturing industry practice indicated, reduces the reject through the improvement entire manufacture craft, must compared to process the reject which factory processing already discharged to save the expenditure greatly.The green manufacture realization may achieve the goal through the computer simulation, namely it is a hypothesized manufacture part. Looked from the sustainable development viewpoint that, the green manufacture is chooses inevitably, it will become the modern integration manufacture system an important constituent.We may see from above analysis: Each kind of advanced technique of manufacture is the interdependence, each other overlapping, under advanced technique of manufacture this building, the modern integration manufacture system becomes its core, and develops along with the advanced technique of manufacture unceasing development, namely the modern integration manufacture system should be a dynamic concept.。 Our country modern integration manufacture system development strategy In under the market competition impetus, the advanced technique of manufacture development is extremely rapid, the new thought, the new concept emerge one after another incessantly, through to the modern integration manufacture system and the advanced technique of manufacture relations analysis, we thought when formulates our country modern integration manufacture system development strategy, should pay great attention to the humanist thought, the utilization parallel projects philosophy, causes each kind of advanced technique of manufacture to link up mutually, the coordinated development, and absorbs the advanced technique of manufacture unceasingly the mature achievement, widely applies the promotion function for the advanced technique of manufacture in our country. Therefore we should achieve: (1) Take the enterprise demand as the starting point, take “flings the chart board” the project as the turning point, popularizes the CAD technology vigorously, helps the enterprise to carry on the personnel to train, improves the enterprise personnels quality (including technical level, work manner, moral level and so on), enhances the enterprise unceasingly the management level, in computer integration manufacture system success demonstration enterprise prompt promoted parallel projects, and suitable thought and the technology and so on propaganda hypothesized manufacture, agile manufacture, provide the solid foundation for enterprises further development.(2) In the technical advanced aspect, do not need to pursue the world to be in the lead excessively, should act according to the enterprise actual request, the solution actual problem, argues vigorously creates the benefit as soon as possible, obtains the enterprise by this the support and obtains in the fund the help, in order to form the positive cycle, promotion research work further development. At the same time, should participate in the international cooperation, the track international research tendency, certainly, also may introduce some keys suitably, has the development potential technology, carries on the digestion and the innovation, reduces our country and the world advanced level disparity, maintains certain technology to be in the lead. (3) Aims at weakness which our country scientific research strength disperses, the imitating disperser network production thought, using the computer network, the development cooperation research, builds the distributional network research center, coordination carries on the technical attack. The so-called distributional network research center is uses the information technology, the networking, the computer technology to in the reality research person, the thing, the information and the research process carries on the comprehensive integration, in certain time in order to the common goal does the research by the best personnel and the unit combination, transfers various aspects the enthusiasm through the joint operation to achieve the research work widely develops with carries on thoroughly, reduces the scientific research cycle, the enhancement scientific and technical payoffs competitive power, also may say the distributional network research center is the realistic development facility function in the network mapping, is one kind “hypothesized” working pattern. In summary, develops our countrys modern integration manufacture system to be supposed take enterprises demand as the power, through governments policy and the plan coordination, continues to develop the parallel projects, the hypothesized manufacture, the agile manufacture and the green manufacture research and the application thoroughly, and using the distributional network research center, organizes various local the scientific research concentration of efforts breakthrough and the modern integration manufacture system close correlation like the STEP standard application, the CORBA standard promotion, the enterprise process restructuring theory research and so on has the significant strategic sense fundamental research work, causes the modern integration manufacture system to become our country manufacturing industry gradually the soul.現(xiàn)代集成制造系統(tǒng)的技術(shù)構(gòu)成及發(fā)展策略研究信息技術(shù)的發(fā)展引起的革命使我們進(jìn)入了信息時代。信息革命不僅引起人們的思想觀念、生活方式的變化，而且導(dǎo)致了生產(chǎn)方式和制造哲理的巨大變化，可以說近十年來提出的新的制造哲理都離不開信息技術(shù)提供的支撐，以信息化制造技術(shù)為代表的先進(jìn)制造技術(shù)正使制造業(yè)處于重要的歷史性變革時期。多年來，我國的綜合國力不斷增強(qiáng)，入關(guān)在即，市場競爭十分激烈，國內(nèi)市場已從賣方市場轉(zhuǎn)化為買方市場，而且正在迅速成為國際市場的一部分，許多大中型企業(yè)在競爭中處于不利地位，甚至破產(chǎn)、倒閉。本文結(jié)合我國國情，通過分析現(xiàn)代集成制造系統(tǒng)與先進(jìn)制造技術(shù)的關(guān)系，論述了我國現(xiàn)代集成制造系統(tǒng)的技術(shù)構(gòu)成和發(fā)展策略及途徑，希望為我國制造業(yè)的發(fā)展做些有益的探索。 現(xiàn)代集成制造系統(tǒng)的含義與定位 現(xiàn)代集成制造系統(tǒng)（Contemporary Integrated Manufacturing System）是計(jì)算機(jī)集成制造系統(tǒng)新的發(fā)展階段，在繼承計(jì)算機(jī)集成制造系統(tǒng)優(yōu)秀成果的基礎(chǔ)上，它不斷吸收先進(jìn)制造技術(shù)中的相關(guān)思想的精華，從信息集成、過程集成向企業(yè)集成方向迅速發(fā)展，在先進(jìn)制造技術(shù)中處于核心地位。具體地說，它將傳統(tǒng)的制造技術(shù)與現(xiàn)代信息技術(shù)、管理技術(shù)、自動化技術(shù)、系統(tǒng)工程技術(shù)進(jìn)行有機(jī)的結(jié)合，通過計(jì)算機(jī)技術(shù)使企業(yè)產(chǎn)品在全生命周期中有關(guān)的組織、經(jīng)營、管理和技術(shù)有機(jī)集成和優(yōu)化運(yùn)行，在企業(yè)產(chǎn)品全生命周期中實(shí)現(xiàn)信息化、智能化、集成優(yōu)化，達(dá)到產(chǎn)品上市快、服務(wù)好、質(zhì)量優(yōu)、成本低的目的，進(jìn)而提高企業(yè)的柔性、健壯性和敏捷性，使企業(yè)在激烈的市場競爭中立于不敗之地。從集成的角度看，早期的計(jì)算機(jī)集成制造系統(tǒng)側(cè)重于信息集成，而現(xiàn)代集成制造系統(tǒng)的集成概念在廣度和深度上都有了極大的擴(kuò)展，除了信息集成外還實(shí)現(xiàn)了企業(yè)產(chǎn)品全生命周期中的各種業(yè)務(wù)過程的整體優(yōu)化，即過程集成，并發(fā)展到企業(yè)優(yōu)勢互補(bǔ)的企業(yè)之間的集成階段。 現(xiàn)代集成制造系統(tǒng)的技術(shù)構(gòu)成 先進(jìn)制造技術(shù)（AMTAdvanced Manufacturing Technology）作為一個專有名詞至今還沒有一個明確的、一致公認(rèn)的定義。通過對其內(nèi)涵和特征的研究，目前共同的認(rèn)識是：先進(jìn)制造技術(shù)是傳統(tǒng)制造技術(shù)不斷吸收機(jī)械、電子、信息、材料、能源和現(xiàn)代管理等方面的成果，并將其綜合應(yīng)用于產(chǎn)品設(shè)計(jì)、制造、檢測、管理、銷售、使用、服務(wù)的制造全過程，以實(shí)現(xiàn)優(yōu)質(zhì)、高效、低耗、清潔、靈活的生產(chǎn)，并取得理想技術(shù)經(jīng)濟(jì)效果的制造技術(shù)的總稱它具有如下一些特點(diǎn)： 從傳統(tǒng)的順序工作方式向并行工作方式轉(zhuǎn)變，縮短工作周期，提高工作質(zhì)量； 從按照功能劃分部門的固定組織形式向動態(tài)的自主管理的小組工作方式轉(zhuǎn)變。在先進(jìn)制造技術(shù)中，現(xiàn)代集成制造系統(tǒng)在吸收計(jì)算機(jī)集成制造系統(tǒng)的優(yōu)秀成果的基礎(chǔ)上，繼續(xù)推動并行工程、虛擬制造、敏捷制造和動態(tài)聯(lián)盟的研究工作深入進(jìn)行，并不斷吸收先進(jìn)制造技術(shù)中的成功經(jīng)驗(yàn)和先進(jìn)思想，將它們進(jìn)行推廣應(yīng)用，由此使現(xiàn)代集成制造系統(tǒng)成為先進(jìn)制造技術(shù)的核心，具體說明如下： 1、并行工程（CEConcurrent Engineering）： 并行工程是集成地、并行地設(shè)計(jì)產(chǎn)品及其相關(guān)過程（包括制造過程和支持過程）的系統(tǒng)方法。它要求產(chǎn)品開發(fā)人員在一開始就考慮產(chǎn)品整個生命周期中從概念形成到產(chǎn)品報廢的所有因素，包括質(zhì)量、成本、進(jìn)度計(jì)劃和用戶要求。為了達(dá)到并行的目的，必須建立高度集成的主模型，通過它來實(shí)現(xiàn)不同部門人員的協(xié)同工作；為了達(dá)到產(chǎn)品的一次設(shè)計(jì)成功，減少反復(fù)，它在許多部分應(yīng)用了仿真技術(shù)；主模型的建立、局部仿真的應(yīng)用等都包含在虛擬制造技術(shù)中，可以說并行工程的發(fā)展為虛擬制造技術(shù)的誕生創(chuàng)造了條件，虛擬制造技術(shù)將是以并行工程為基礎(chǔ)的，并行工程的進(jìn)一步發(fā)展就是虛擬制造技術(shù)。同時，并行工程是在CAD、CAM、CAPP等技術(shù)支持下，將原來分別進(jìn)行的工作在時間和空間上交叉、重迭，充分利用了原有技術(shù)，并吸收了當(dāng)前迅速發(fā)展的計(jì)算機(jī)技術(shù)、網(wǎng)絡(luò)技術(shù)的優(yōu)秀成果，使其成為先進(jìn)制造技術(shù)中的基礎(chǔ)。 2、虛擬制造（VMVirtual Manufacturing）： 虛擬制造利用信息技術(shù)、仿真技術(shù)、計(jì)算機(jī)技術(shù)對現(xiàn)實(shí)制造活動中的人、物、信息及制造過程進(jìn)行全面的仿真，以發(fā)現(xiàn)制造中可能出現(xiàn)的問題，在產(chǎn)品實(shí)際生產(chǎn)前就采取預(yù)防措施，從而達(dá)到產(chǎn)品一次性制造成功，來達(dá)到降低成本、縮短產(chǎn)品開發(fā)周期，增強(qiáng)產(chǎn)品競爭力的目的目前，虛擬制造技術(shù)已經(jīng)在國外有所應(yīng)用，例如：美國Boneing公司設(shè)計(jì)的一架VS-X虛擬飛機(jī)，可用頭盔顯示器和數(shù)據(jù)手套進(jìn)行觀察與控制，使飛機(jī)設(shè)計(jì)人員身臨其境地觀察飛機(jī)設(shè)計(jì)的結(jié)果，并對其外觀、內(nèi)部結(jié)構(gòu)及使用性能進(jìn)行考察；國內(nèi)的研究剛剛起步，主要集中在三個方面（1）產(chǎn)品虛擬設(shè)計(jì)技術(shù)： 主要包括虛擬產(chǎn)品開發(fā)平臺、虛擬測試、虛擬裝配以及機(jī)床、模具的虛擬設(shè)計(jì)實(shí)現(xiàn)等。其中清華大學(xué)利用美國國家儀器公司的Labview開發(fā)平臺實(shí)現(xiàn)了鎖相電路的虛擬（2）產(chǎn)品虛擬制造技術(shù) 主要包括材料熱加工工藝模擬、加工過程仿真、板材成型模擬、模具制造仿真等。北航與一汽用OPTRIS開發(fā)的板料成型軟件已經(jīng)基本能夠模擬類似車門的中等復(fù)雜程度的汽車覆蓋件和其他沖壓成型件的沖壓成型過程；（3）虛擬制造系統(tǒng) 主要包括虛擬制造技術(shù)的體系結(jié)構(gòu)、技術(shù)支持、開發(fā)策略等。從以上的論述中可以看到國內(nèi)外研究水平差距是很大的，而且由于虛擬制造技術(shù)既是并行工程的發(fā)展方向又是敏捷制造的核心，這就決定我們必須以它作為現(xiàn)代集成制造系統(tǒng)的中心技術(shù)，以帶動相關(guān)技術(shù)的研究工作的進(jìn)行，并使它們協(xié)同一致順利地發(fā)展。 3、敏捷制造（AMAgile Manufacturing）： 敏捷制造是以競爭力和信譽(yù)度為基礎(chǔ)，選擇合作者組成虛擬公司，分工合作，為同一目標(biāo)共同努力來增強(qiáng)整體競爭能力，對用戶需求作出快速反應(yīng)，以滿足用戶的需要。為了達(dá)到快速應(yīng)變能力，虛擬企業(yè)的建立是關(guān)鍵技術(shù)，其核心是虛擬制造技術(shù)，即敏捷制造是以虛擬制造技術(shù)為基礎(chǔ)的。敏捷制造是現(xiàn)代集成制造系統(tǒng)從信息集成發(fā)展到企業(yè)集成的必由之路，它的發(fā)展水平代表了現(xiàn)代集成制造系統(tǒng)的發(fā)展水平，是現(xiàn)代集成制造系統(tǒng)的發(fā)展方向。 4、綠色制造（GMGreen Manufacturing）： 綠色制造是一個綜合考慮環(huán)境影響和資源效率的現(xiàn)代制造模式，其目標(biāo)是使得產(chǎn)品從設(shè)計(jì)、制造、包裝、運(yùn)輸、使用到報廢的整個產(chǎn)品生命周期中，對環(huán)境的影響（負(fù)作用）最小，資源的使用效率最高。綠色制造的提出是人們?nèi)找嬷匾暛h(huán)境保護(hù)的必然選擇，發(fā)展不能以環(huán)境污染為代價，國際制造業(yè)的實(shí)踐表明，通過改進(jìn)整個制造工藝來減少廢棄物，要比處理工廠處理已經(jīng)排放的廢棄物大大節(jié)省開支。綠色制造的實(shí)現(xiàn)可以通過計(jì)算機(jī)仿真來達(dá)到目的，即它是虛擬制造的一部分。從可持續(xù)發(fā)展戰(zhàn)略的觀點(diǎn)看，綠色制造是必然選擇，它將成為現(xiàn)代集成制造系統(tǒng)的一個重要的組成部分。 從以上的分析中我們可以看到：各種先進(jìn)制造技術(shù)是相互關(guān)聯(lián)、彼此交叉的，在先進(jìn)制造技術(shù)這一大廈下，現(xiàn)代集成制造系統(tǒng)成為它的核心，并隨著先進(jìn)制造技術(shù)的不斷發(fā)展而發(fā)展，即現(xiàn)代集成制造系統(tǒng)應(yīng)該是一個動態(tài)的概念。我國現(xiàn)代集成制造系統(tǒng)的發(fā)展策略 在市場競爭的推動下，先進(jìn)制造技術(shù)發(fā)展十分迅速，新思想、新概念層出不窮，通過對現(xiàn)代集成制造系統(tǒng)與先進(jìn)制造技術(shù)關(guān)系的分析，我們認(rèn)為在制定我國現(xiàn)代集成制造系統(tǒng)的發(fā)展策略時，應(yīng)該注重以人為本的思想，運(yùn)用并行工程的哲理，使各種先進(jìn)制造技術(shù)相互銜接、協(xié)調(diào)發(fā)展，并不斷吸收先進(jìn)制造技術(shù)的成熟成果，為先進(jìn)制造技術(shù)在我國的廣泛應(yīng)用起到促進(jìn)的作用。所以我們應(yīng)該做到： （1）以企業(yè)需求為出發(fā)點(diǎn)，以“甩圖板”工程為契機(jī)，大力普及CAD技術(shù)，幫助企業(yè)進(jìn)行人員培訓(xùn)，提高企業(yè)人員的素質(zhì)（其中包括技術(shù)水平、勞動態(tài)度、道德水平等），不斷提高企業(yè)的管理水平，在計(jì)算機(jī)集成制造系統(tǒng)成功示范企業(yè)中及時推廣并行工程，并適當(dāng)宣傳虛擬制造、敏捷制造等思想和技術(shù)，為企業(yè)的進(jìn)一步發(fā)展提供堅(jiān)實(shí)的基礎(chǔ)。 （2）在技術(shù)的先進(jìn)性方面，不要過度追求世界領(lǐng)先，應(yīng)該根據(jù)企業(yè)實(shí)際要求，解決實(shí)際問題，力爭盡快創(chuàng)造效益，以此取得企業(yè)的支持并獲得資金上的幫助，以便形成良性循環(huán)，促進(jìn)研究工作的進(jìn)一步開展。同時，應(yīng)該參與國際合作，跟蹤國際研究動態(tài)，當(dāng)然，也可以適當(dāng)引進(jìn)一些關(guān)鍵的、有發(fā)展?jié)摿Φ募夹g(shù)，進(jìn)行消化和創(chuàng)新，縮短我國與世界先進(jìn)水平的差距，保持一定的技術(shù)領(lǐng)先性。 （3）針對我國科研力量分散的弱點(diǎn)，仿照分散網(wǎng)絡(luò)化生產(chǎn)的思想，利用計(jì)算機(jī)網(wǎng)絡(luò)，開展合作研究，建立分布式網(wǎng)絡(luò)化研究中心，協(xié)調(diào)一致進(jìn)行科技攻關(guān)。所謂分布式網(wǎng)絡(luò)化研究中心就是利用信息技術(shù)、網(wǎng)絡(luò)技術(shù)、計(jì)算機(jī)技術(shù)對現(xiàn)實(shí)研究活動中的人、物、信息及
