The software quality of the computers for the power system’s control must satisfy some basic requirements ; maintainability, modifiability, reliability, be understandable etc. So, in the previous paper, we argued the necessity of hierarchical decomposition of the software system for the power system’s control, and proposed a method of hierarchical software decomposition which makes it easy to document, to coodinate and to maintain the software system. In this paper, we propose a software designing technique by which we can design optimum software system by evaluating the hierarchical software decomposition proposed in the previous paper. Although the evaluating technique used in this paper is a popular one, as far as the coefficients of the evaluation functions are adequate to the system and programming team, the softwave system designed by this technique would be an optimum one. The proposed technique can be used in other control systems in addition to the power system’s control by ajustion the method and criterions of evaluation for them.
