Fictitious production technology is one of advanced production technologies that appear in last few years, it is a kind of when the enterprise becomes a basis with information market new production technology. The article undertook summarizing to fictitious production technology, introduced fictitious production technology to make yield application and its application prospect in production. 1 preface is making the application in the system as the computer, automation and network technology, the effect that IT develops to making a technology is bigger and bigger. The product makes the information investment in the process, oneself the main factor that makes decision product cost. IT makes contemporary production technical content rises, make traditional production technique produces simple change. IT also is promoting the modernization that designs a technology, the precision that treatment makes is changed, change quickly, of automation technology flexible change, intelligence is changed, the network of whole production process, globalization. At the beginning of 80 time, the CIMS that advanced production technology makes core with information market (CIMs: ComputerImegratedManuf begins to get executive like TuringSystem) ; 80 time end, the collateral project that becomes nucleus with process market (CE: CocurrentEngineering) technology rose to make a standard further; Take a person 90 time, advanced production technology develops to higher level further, appeared fictitious make (VM: Profit of VinualManufacturing) , seed produces (LP: Kan Production) , nimble make (AM: A100 LeM dregses of rice - Ufacturing) , dummy company (VE: The new idea such as VinuaiEnterprise) . In these a lot of new ideas, "Fictitious make " the wide attention that caused people, become one of heat of research. 2 empty are like production technology fictitious making is science and technology of a kind of computer actually, it is pillar with IT, emulation technology, virtual reality technology, before products plan or the physics of production system come true, the performance that can make human body is met or finds prospective product perhaps creates systematic position, of sex of the look up before can be being made thereby decision-making with optimize executive plan. The by nature is fictitious making is the dynamic simulation that makes to real product, it is a kind of imitate that undertake on the computer and does not drain physical resource makes software technology. It is had build model and emulation environment, make the product plans from manufacturing process, craft, attemper plan, logistics is supplied and money is met, purchase and manage wait for a kind compositive, integrated production environment, before the production activity of real product, with respect to the function that can calculate a product and production system condition, of sex of the look up before can be being made thereby decision-making and optimize executive plan. Fictitious make from go up at all the traditional production pattern that changed production of design, trial-produce, modification design, dimensions. Make truly in the product before going out, soft product prototype is generated to replace traditional good specimen to have a test in fictitious production environment, to its function and producibility undertake forecast and be evaluatinged, shorten thereby the design of the product and production cycle, reduce the development cost of the product, raise a system to answer the ability of vicissitude of the market quickly. With make actually compare, fictitious production main characteristic is: (1) product and production environment is fictitious model, products plan has to fictitious model on the computer, make, test, design personnel or user even but " enter " fictitious production environment examines its design, treatment, assemble and operate, and revise what do not rely on traditional archetypal prototype repeatedly; Still but the product that already will develop (component) deposit in the computer, not only charge of greatly economic storage, can change a design quickly according to user demand or vicissitude of the market more, throw batch production quickly, can reduce the development time of new product substantially thereby, improve quality, reduce cost. (2) can make distributing to be in in the different professional of different spot, different branch same work at the same time on product model, mutual communication, information is shared, reduce many documentation to make the time that reachs its to deliver and error, make product development answers vicissitude of the market with quick, high grade, low cost thereby. 3 fictitious production technologies make yield application in production a product is designed from the concept put in the market, namely the manufacturing cycle of the product can be divided by time order for the concept design, detailed design, treatment is made, check and groom ／ is safeguarded, it is OK that empty is like production technology the effect with each in producing cycle entirely level main play in the product. 3. The 1 product that is based on empty to be like production technology develops what empty is like production technology to be enmeshed gender and alternant sex character make it is become use design new product and the capable tool that develop corresponding product line. Consider to design above all and construct the time that prototype of a new product needs. In designing a process, stylist should consider each aspects of the product, protect in order to satisfy certain security, ergonomics, easy dimension gender and assemble a standard. Accordingly, in designing a process, get strictly the limitation of production, time and charge. Empty is like make can finish than CAD more functions, CAD considers a product only normally the geometrical feature of each stature component and mutual the geometric constraint between. And be like in empty in making, the condition that a variety of place that can mention above require to satisfy is compositive consider along with all the others in designing a process, we still can decrease appropriately child component amount, can put in proportion even shrink component dimension, this reduced design charge and archetypal and tectonic time greatly, further the goal that achieves product user to change. For example the appearance design of plane, car, whether does its appearance accord with aerodynamics principle, the obstruction in athletic process, the rationality of composition of its interior structure. In design of complex pipeline system, use fictitious technology, the architect is OK " enter among them " undertake conduit is decorated, can check whether produce interference. In the fictitious products plan on the computer, not only can improve design efficiency, and the problem that can discover the design is medium as early as possible, optimize the design of the product thereby. Applied computer emulates a technology, of ordinal to the treatment method of the spare parts, working procedure, tool choose, of craft parameter choose, treatment craft sex, ship-fitter art sex, cooperate between cooperate gender, join the motility of the join sex between, moving link all can build a model to emulate, can discover treatment flaw ahead of schedule, discover the problem that when assembling, appears ahead of schedule, can optimize production process thereby, improve treatment efficiency. What the product produces a course is reasonable make, stock of manpower resource, production resource, stock, production attempers, the program design that produces a system, all can emulate through the computer undertake optimizing, still can be opposite at the same time manufacturing system undertakes dependability is analysed, undertake analytic forecasting to producing the capital of the process, undertake analytic forecasting waiting to product market, be opposite thereby the reasonable configuration of manpower resource, production resource, to shrinking short sawn timber produces cycle, reduce cost import great. 3.
What 2 empty are like production technology to produce scheduling in the application on manufacturing scheduling is visible decision-making to making it is extremely useful, but at present it still fails to come true completely. Use empty is like production technology, but will thousands of product, by tens of thousands component and a lot of other factor of production are visible, assistant planner is evaluated better, the choice produces a plan. The picture that the computer produces can change the cerebrum burden of planner their organic system, this accelerated working process. Manufacturing plan data becomes stereo or multidimensional graph, can express complex in-house concern. 4 last words are fictitious production technology is one of vital technologies that informatization makes, realize the technology with fictitious production strong need to prop up, the application of fictitious production technology should combine the characteristic of oneself of our country manufacturing industry, bold on the foundation that absorbs foreign mature experience innovation, form characteristic development. OK and fatidical, what study to fictitious production technology as our country is thorough, its wide application already by a definite date is not far, will become a modern informatization to make the only way of the enterprise eventually.
