Products plan and the root nature of production environment change, brought about the formation of the new idea that information age product develops: The products plan of information age and make, it is a feature in order to face the complete lifecycle of the product, collateral change (the serial way that changes a tradition is collateral means) , compositive change (the compositive) of the compositive, personnel of the compositive, technology of the compositive, resource of information, flexible change and change adroitly (the demand that answers a client quickly, what expression is a structure to go up is fast recombine, answer) on function quickly, implement high automation finally thereby. And relatively fixed, resource centers traditional constituent structure relatively, it is with regional economy the dominant, products plan that is a feature in order to face a product and production mode, already did not suit to it, urgent need builds drive of demand of a kind of market, have the products plan that answers a mechanism quickly and create new pattern -- network design and make. Contemporary design is different from the mode of 1 design of different ground collaboration that is based on a network to be designed traditionally, it is the change as a result of situation of market competition and technical progress, when is it awaited than holding the post of in the past more rely on new knowledge get, is not experience. Design knowledge getting ability is a kind of comprehensive strength, include actual strength of management level, technology level, capital, talent actual strength, advanced equipment and past experience. Their summation, can regard the resource that design knowledge gets as. The enterprise of the developed country is developed with research more (the constituent form of R&D) center will develop this kind of resource. Our country enterprise because the reason of each respect, want interiorly to develop this kind of resource, no matter be assemble of capital investment, talent, equipment,supply, or experience is accumulated, be very difficult inside brief period. But on the other hand, our country also exists really quite the resource that knowledge of a batch of designs in can supporting a product to develop gets. These resource mostly in the orgnaization such as place of courtyard of consist in scientific research, universities and colleges and key laboratory. Rise to design this kind distributedly intellectual natural resources to make full use of, get on district namely dispersive, the research development force with relatively weak force becomes force in the conformity inside brief period the research with powerful, higher level develops a group, finish the design job of specific project in order to be inside shorter time, a kind of different ground collaboration that is based on a network designs pattern -- fictitious research develops a center (of Virtual R&D) establish appear very necessary. The characteristic with the mainest center of fictitious research development is resource is shared, include intellectual natural resources and manpower resource. In central interior the information resource of each member units is shared, talent resource can develop as the project need and recombine. Of all resource using is to be based on information freeway namely network, and go up unlike traditional sense develop in coordination. Center of fictitious research development is the constituent form on notional meaning, it does not break original constituent management form, need a kind of built dynamic alliance according to the project however. Graph the architecture of center of development of 1 fictitious research pursues 1 gave out the block diagram of construction of system of center of fictitious research development. Fictitious research develops a center to basically include 3 systems, namely information system, management system and technical support system. The organization that runs a system to be in charge of a project designing and center external contact, it is central organizer, coordinator and controller: Information system basically manages relevant domain to design what information designs between intellectual collection and member unit to share harmonious: The technology supports a system to be comprised by a certain number of project groups, a project that project group is the origin architect composition from each member units develops a panel, go up in district they are dispersive, coupling theirs is some design task, area of the Web browser that they get on through the network, frequency, video, public Chat and white board the discussion that has real time news and communication, each architect can design different part at the same time, it is filestore next in database system, after restoring a file from inside the server, the producibility that has a product is evaluated (DFM) , can assemble a gender to analyse (DFA) , different architect returns the modification of achievable different share. Because each member units are in,the different way of same design domain has an advantage, accordingly they can learn from others's strong points to offset their weakness, play gives integral advantage, will respective inside brief period advantage is compositive in some project, make design level achieves this purpose to exceed international even thereby congener product level. The 2 network that are based on Agent create pattern contemporary production main feature is intelligence is mixed fast, intelligence is to point to the intelligence that uses a person above all, knowledge, experience and the faculty that include craft inside, also use artificial intelligence at the same time: It is agile to the response of the market of client drive and quick quickly. Its mode has make remotely, make adroitly, network is made etc. The production resource connection that network makes a system pass a network to will be in each district enterprise dispersedly rises, those who realize production resource is effective use and share, and the change as market demand, establish quickly with cancel, fast enter with exit the market. This uses new effective organization with respect to the requirement configuration and run decision-making mechanism, the trends that can implement production system through simple control regulation recombines with moving control, to solve this difficult problem, a kind of network that is based on distributed heterogeneous Agent to seek solution in coordination made systematic pattern arise: It is the is main feature from the organization distributed intelligence with individual autonomic sex and whole changes systematic pattern. Numerous the independent production that has autonomic behavior capacity is individual Agent passes simple control regulation interaction, form systematic whole organize oneself, suit oneself with from developmental conduct competence, what implement production system thereby is fast recombine to be controlled with behavior. Graph 2 be based on Agent network to make an environment be in production environment, the functional substance that an Agent place represents can be an an a production enterprise, production workshop, production equipment or system of a software. Achieve the kind of oneself task according to each function substance, can be its cent 3 kinds: Automatic system (exactly the amount controls device) , man-machine system (like CAD system) with the person in making or organization. Accordingly, the Agent that can use 3 kinds of different functions and structure acts as agent as its, namely automatic system Agent, man-machine system Agent and natural Agent. Each Agent in production environment rises through computer network join, form be based on Agent distributed network to create an environment, see a picture 2. If the functional substance of delegate of each Agent place is independent production company, form environment of network of alliance of a kind of business, between implementation enterprise compositive: If the functional substance of delegate of each Agent place is the functional subsystem of enterprise interior, form environment of enterprise interior network, those who realize enterprise interior is compositive. When some function substance Agent accepts a product to make news (the NC code) that becomes like products plan have a youthful look, it will choose to create pattern according to the characteristic of the product, choose a proper partner cooperation quickly to finish from inside other function substance next. Of research of American current electric equipment and development department " CAM network (Computer Aided Manufacturing Network) " use this principle to make namely the member of compositive enterprise can join quickly and share production information. In addition, flexible production system (FMS) , CIMS (system of CIMS) , robot is applied extensively at network manufacturing industry. In the network service system with compositive CAD/CAM/CAPP/CAX, the user inputs product information, the system can generate complete CAD/CAM/CAPP/CAX file to control long-range production equipment to complete treatment process, the system uses a webpage to build an interface between user and network service system, make the user makes equipment remotely through Internet operation. Graph the 3 phase that are based on the network, fictitious product that faces product complete lifecycle to develop technical product lifecycle to include and content see the content of 3 products lifecycle graph 3. This is one arrives by the market the circular process of the market, include a product to develop level, product to make level, product sell level, product to use level and product to reclaim level. Face the design of product lifecycle, designing namely at the beginning, with respect to the influencing factor that mature design involves likely downstream, because of,the ability after avoiding to be finished in some design phase as far as possible realizes craft, make those who wait for an element create this level of program of whole even design change. This has a kind to be able to make sure departmental door is timely with respect to the requirement the collateral work environment of communication. Consider product lifecycle in the round to level is developed in the product the requirement of each phase, appeared to have the CAE system of fast evaluation and DFX system to devising plan. More practical relevant technology is reflected centrally in DFX respect, include to face function to design (DFP) , face assemble a design (DFA) , face production design (DFM) , face a test to design (DFT) , face quality to design (DFQ) , face cost to design (DFC) , face service and maintenance design (DFS) . How to plan these technologies real time, dynamicly to be in one? Additional, in product development process, still have an important segment, it is sample experiment phase, this is already costly the phase of take time. Shorten for utmost ground the product develops time, have use digitlization experiment model without the likelihood (Digital Mock-up) replaces objective experiment model (Physical Mock-up) . Still have, can deny make the client participates in product development directly, include ground of be personally on the scene to check product function and sense of reality to suffer the performance characteristics of the product. To solve afore-mentioned problems, a kind of design mode that is based on network technology and virtual reality technology -- fictitious product develops technical emerge as the times require. Technology of fictitious product development basically includes fictitious design and fictitious create two fields. Fictitious product stores namely the product data model in computer interior. The product builds model, data to share the base that with process copy really fictitious product develops a technology. For the design to fictitious product, treatment, assemble, performance characteristics undertake building a model, must ask complete and reliable product is described, include a product to define data itself not only, still include the description of all and corresponding environment inside product lifecycle, and the description of product and environmental interaction rule, and the description of product and environmental interaction rule. The analysis that relies on product of emulation technology imitate next, treatment, rig a process, make whole product is built in the computer come out, undertake metrical to emulating a result again, analysis, in order to decide the product satisfies whether OK market demand, real production. In process of whole product development, the alternant sex that uses virtual reality technology (Interaction) , be enmeshed quality (Immersion) and imaginary sex (the height that Imagination) reachs imitate product to develop an environment is distinct change, make the person can is opposite fictitious prototype has alternant operation directly, produce the feeling of be personally on the scene. And among them all data and other information are executed through the network share. At present technology of fictitious product development is in Boeing 777 get applied with European airbus company, make the development cycle of the product parts thereby by 8 years, decrease 4 years to be mixed to 5 years 2. 5 years. The choice mechanism of the 4 partners that are based on Agent faces some market opportunity, if where,the enterprise chooses right partner quickly in allied network. In network design and in production system, choice work of the partner is completed by intelligent Agent. The partner in business alliance network has the following kinds of kinds: Design companionate, production associate and supplier. Choose companionately to be a choice mechanism that will analyse the partner that is based on Agent with the design below. Graph the total construction of the Agent of total construction intelligence of 4 intelligence Agent is shown 4 times like the graph. Of function of its basis interior different and OK cent becomes 4 administrative levels: Communication layer, cooperative control layer, define layer and expressional layer oneself. Among them communication layer is managed by communication implement composition, cooperative control layer by consultative inference machine and cooperate with knowledge base composition, comprise by cognitive inference machine and ability knowledge base from definition layer, and expressional layer behaves interface to behave by the multimedia information of Agent. The in-house behavior expression when such an intelligence Agent are choosing a partner is: Communication management implement accept external environment information (the information that comes from the market and requirement) , by inferential control machine (include consultative inference machine and cognitive inference plane) according to these messages and requirement, after undertaking analysis, understanding, inference, choose a right partner quickly from inside business alliance contact. With maths the model describes the inference when intelligent Agent is choosing a partner to control algorithm below. Assume some intelligence Agent is seeking the company that has design capacity, set Q1, q2, ... , qm is M the company that can offer an alternative, y1, y2, ... , yn is N influencing factor (wait for) like talent, equipment, technology, charge and credit. Above all, want to determine the relative value of every influencing factor, seek the authority number that gives every influencing factor by inferential control machine namely, it is W1 suppose here, w2, ... , wn, among them the authority number that Wi is Yi, w1+w2+ ... + Wn=1. Then, to each Hou Xuan by inferential control machine the enterprise presses each influencing factor to undertake assessment, next, beg give every to await the authority number that picks an enterprise to fall in each influencing factor, if express,1 is shown. Watch 1 await the advantageous position that picks an enterprise to fall in every influencing factor to count influencing factor Y1Y2... YnQ1w11w21... Wn1Q2w12w22... Wn2... Qnw1mw2m... Wnm is final, await the advantageous position that picks an enterprise to fall in every influencing factor to multiply by every be counted with the authority of this influencing factor and addition, its and S are mark of appraise of this enterprise general comment, namely · W2+ of W1+w2i of · of S = W1i... + Wni · Wn, I = 1, 2, ... , m notchs highest person pick a company to obtain namely. The key of the problem is how to seek the authority number that gives every influencing factor, and every await the authority number that picks an enterprise to fall in every influencing factor. In inferential control machine, the arrangement that according to American operational research domestic Satty offers analyses a way and apply trigonometry ambiguous number can undertake begging solving to afore-mentioned problems. Complete the selection that designs associate finally thereby. CNC Milling
