Recently developments with short-term and lower cost are strongly required for shorten life cycle of products. For these problems, FEM simulation is used to predict the result of processing instead of real test. The other side, TAGUCHI methods for robust design are also used to decide optimum processing conditions with narrow dispersion. In our former study, we had developed and evaluated regarding a simulation system of CAE without trial working for the products. In this study, the system was first manufactured for calculating regarding the optimum conditions on the design. This system consists of TAGUCHI methods, commercially produced CAE and management of productivity. The TAGUCHI methods were used for calculating SN ratio, sensitivity, average and standard deviation for all combination of all parameters. The CAE was used for shortening the total time of evaluation instead of real test. The management of productivity was used for selecting the optimum value regarding all parameters. The system was remade for high precision system using dispersion of error factors. Accuracy of the system was finally checked by using a few mathematical models. It is concluded from the result that; (1) The simulation system on CAE without trial working for products could use for deciding the optimum conditions on the design, (2) The system could consider regarding effect of using dispersion of error factors, (3) Accuracy of the system was excellent, and the system would use effectively in the industrial world.
