| Abstract: | A new method of how to establish and calculate this optimal problem on basis of model stage database is studied, which includes principle of optimization, objective function, restrict condition, neat optimal point and so on. The method will enable designers get a optimal design that can satisfy the requirement of multi design points with better efficiency and approach to maximum of the objective function. A sample is been shown here to explain the designing process and the method can be used in practice design. |
