A Function Evaluation by Fuzzy Set in Value Engineering

가치공학(VE)에 있어 Fuzzy Set을 이용한 기능평가 방법

In conventional function analysis, the function values are evaluated by experts, which are treated as exact values. For many cases, it is often difficult to evaluate the function values of a certain subject because the criteria of evaluation are very vague. This paper presents a new function evaluation method using fuzzy set. The purpose of the method is to minimize the difference among experts by recognizing an intersection point of membership function as a representative value.
