To realize actual designs in computer aided design, we introduced a design method by the attainability and simultaneous equations to determine structural dimensions in order to make all requirements accomplish their respective objective values. We also introduced an identification method of sensitivity coefficients without theoretical design formulae. We present a multiobjective satisfactory design method that includes non-technical objective functions. Design formulae of the functions are described by orthogonal polynominals, using panel evaluations by the semantic differential method and the regression analysis. Partial derivatives of the formulae give sensitivity coefficients. The iterative solving of the simultaneous equations with the coefficients yields converged or preferred solutions of the design. In a bath unit design with 6 objective functions and 9 design variables, this method produced more precise solutions than the current models in 2〜25 seconds.
