"Emulate " one word interpret from English word " Simulation " , sometimes also interpret is made " imitate " , be " imitate real world " meaning. Introduction of type of 1 system simulation is in project technology group, system simulation is to pass pair of systematic model tests, go studying the system in an existence or design. Expressing a kind is the emulation type of system simulation, model type, computer type and economy. By the watch 1 visible, the computer emulates a when already made system simulation main branch, what system simulation points to greatly is the computer emulate. The development of the development of computer emulation technology and control project, system project and computer project is having close connection. On one hand, control the development of project, system project, promoted the wide application of emulation technology; On the other hand, the development of the occurrence of the computer and computer technology, prop up formidably to emulated technical development to offer again. The computer is emulated serve as a kind of indispensable tool all the time, reducing expenditure of loss, managing funds, shorten the effect with raise the respect such as product quality to be being developed development cycle, main. 2 computers emulate the application in manufacturing industry and manufacturing industry of 　 of development existing state of affairs to have the largest proportion commonly in national economy, since 70 time, global market competition is increasingly intense, product spending structure develops to direction of diversity, individuation ceaselessly, of the product update period be in with date of delivery shorten, technology of a few automation if Ⅱ of CAD, CAM, CAPP, NC, FMS, MRP and CIMS get rapid development. System simulation serves as a kind of important step, can permeate normally go among them, help them implementation is compositive, promoted the development of a few advanced production technologies thereby. In 50 time, the most conspicuous emulation domain is gun control and flight control system; 60 time, it is rocket and missile control system; 70 time are spaceflight, nuclear energy and economic management system; To 80 time, the most conspicuous emulation domain changed direction to make a system stage by stage, and show reveal a kind of vibrant aspect. By nature, emulation technology builds emulation model and a kind of technology to model experiment namely. The implementation of computer emulation course is general but by the computer advanced language, emulation language is finished with emulation software (if pursue,1 is shown) . Typical emulation software has emulation environment, emulation language and program to include 3 kinds of forms, it is not identical that its function is enclothed. From the bottom up, reflected the development process of emulation software roughly. To the later period in 80 time, began to appear unifinication emulates an environment. Now, the emulation that faces production system appeared unifinication props up software, came true to emulate build a model, emulate move, the compositive environment that outputs an analysis, emulation monitoring used intercurrent executive mechanism, the unity that achieved model data, test data, emulation result on the foundation of database management manages, artificial intelligence technology also applies in emulate build a model, in emulating the analysis that move and emulates a result. In addition, broad sense makes system simulation implement appear, the blame language that came true to make a system to some kind builds the function such as drive of data of model, model. This kind of typical unifinication emulates software to have TESS, IBIS; Broad sense emulator has AUTOMOD Ⅱ , FATOR, GEMS, WITNESS. The research heat that 3 computers emulate and the influence 　 to manufacturing industry since 80 time, system simulation ceaselessly forward vertical, horizontal way develops, in manufacturing industry respect, a more apparent progress is " fictitious make " . The basis is fictitious production concept, design and make a preexistence computer of whole product aspirant travel, all sorts of problems that can discover so and solve this product to appear possibly before make. Virtual reality technology (VR -- Virtual Reality) also call fictitious environment technology, clever condition technology, it is a kind of effectively model apery inspect mediumly in environment, listen, use the advanced interactive technology that waits for behavior. It is what to development rises is in on the emulation technology of integrated computer graphics, computer, foundation that passes many science and technology such as feeling technology. It has 2 main features, namely " clever condition feels (Immersive) " and " mutual move (Interactive) " . Pass these 2 main features, virtual reality technology can describe thing interior to reach its mutual a real action and alternant, make the user ases if place oneself in a fictitious world, pull thereby close the distance between user and environment, changed the way of man-machine communication. Use these character of VR technology, can provide support to each phase of the product, design product and its production line below fictitious environment for example, check and assemble the component of the product, the client is OK whether does product of test and verify accord with a requirement to wait. In recent years, the another research heat that computer emulation technology uses in manufacturing industry -- fictitious product development also is conspicuous. Fictitious product is developed (VPD -- Virtual Product Development) result from above all collateral project (CE -- Concurrent Engineer) thought. The constituent form with this kind of thought contemporary and advanced general mixes with modern philosophy, culture for an organic whole, it is right products plan reachs his relevant process (production process, use process and supportive process) undertake running paralell, a kind of systematization that unifinication designs works mode. CE can consider in product development investment, production is made at the beginning, assemble, sell and safeguard and discard as useless all elements of the whole lifecycle that waits for a product, this is very beneficial to resolving the contradiction of products plan and development. VPD is namely below the guidance of CE methodology, rise system of CAD, CS and management of large-scale product data integratedly, form a fictitious product to develop an environment, make the product develops personnel to be able to be in what the place below the product of the plan below this kind of environment, design product, performance that forecasts a product to fall in real environment, feature and true operating mode has to answer, reduce the number that relapse and changes thereby, decrease to cancel to design physical prototype prototype even, can examine well so design, guidance and optimize a design, shorten effectively the development cycle of the product and abundantly save development expenses. VPD emulation technology is the another main field that emulation technology develops, it can arrive deep in the production of all sorts of complex products, can produce enormous economic benefits. Now, the application of emulation technology has moved toward open and complex old system from unitary system. Distributing when emulation object at vast spatio-temporal domain, emulation job requirement is will different situation, different type (include a person inside) when emulation object forms an unified whole to undertake emulation, arose to distributing to be changed interactively emulate (DIS -- Districted Interactive Simulation) . The substance that the bag in this kind of emulation system contains different type, empty body, true substance and tectonic substance, the product of the technology that these substance can be based on different goal system, different years, different manufacturer and different product are comprised, allow them to be operated interactively. The emulation equipment connection that DIS implementation uses computer network to be nodded differently rises, through the data between entity exchange is formed spatio-temporal a kind of when emulate an environment to synthesis advanced emulation technology. Distributing complexly in this kind when comprehensive system undertakes real time is emulated, must offer fast, efficient, many highway and corresponding processing. The United States is the earliest research this kind of technology and throw use country, had finished multinomial be based on fictitious copy true DIS project project, relevant agreement and standard had been finished or finishing. Making a trade, the fictitious research that had produced to be similar to DIS develops center or fictitious business. The center of fast science and technology that Hong Kong productivity promotes bureau and college of Hong Kong city to be built in all is center of development of a fictitious research. In addition, to get used to the world market of rapid change, overcome single company to be in hard short-term inside the limitation that has place to need resource, appeared to be inside certain time limit, for some market opportunity, a kind of trends that binds temporarily through the network is allied -- dummy company. American Boeing (BOEING) the company can accomplish the development of 777 planes, production almost " without blueprint " degree. Boeing is the development of 777 planes, overall design, assemble, component test and all sorts of test-fly, finish by the computer. It can shorten development cycle from 8 original years, managing millions dollar funds. 4 last words are designed from the concept around the product stop use whole lifecycle, wait from policymaker, stylist, manufacturer, distributors and user again all-around the ground goes observe and researching a product, emulation technology already showed its powerful vitality and development potential. Face 21 centuries, like be the same as other sphere, the emulation dimensions of the emulation technology of production domain is expanding ceaselessly, emulation function also is being changed toward intelligence ceaselessly, visible, compositive change, collateral change, the way that distributings to be changed interactively develops.
