Abstract

This paper proposes a fuzzy comparison method called the fuzzy satisfaction function. It compares two fuzzy numbers and produces a fuzzy set on [O, 11 as the comparison result. It represents the possibility that a fuzzy number is greater(smal1er) than the other with a fuzzy set on [0, I]. It is extended from the satisfaction function which compares two fuzzy numbers and generates a value in [0, 11 as the result. This paper summarizes the satisfaction function and proposes the fuzzy satisfaction function. Some numerical examples are also presented in this paper.

본 논문에서는 두 퍼지숫자를 비교하는 퍼지 만족도 함수(fuzzy satifaction function)를 제안한다. 퍼지 만족도 함수는 두 퍼지숫자를 비교하여 그 비교결과로 0과 1사이의 퍼지 잡하을 출력한다.즉 어느 숫자가 다른 숫자보다 클(작을) 가능성이 어느 정도인가를 0과 1사이의 퍼지집합으로 표현한다. 퍼지 만족도 함수는 이전에 제안된 만족도 함수(satisfaction function)를 이용하여 정의되었다. 본 논문에서는 만족도 함수를 간략히 소개하고 이를 이용하여 퍼지 만족도 함수를 제안하며, 이를 퍼지숫자 비교에 적용한 예를 제시한다.
