본 논문에서는 구간값 모호집합 사이의 유사척도를 제안한다. 구간값 모호집합에서는 모호집합의 상한과 하한을 각각 구간값 퍼지집합의 구간으로 표현한다. 제안한 유사척도는 구간값 모호집합 사이의 유사척도를 평가하기 위해 기하학적 거리와 구간값 모호집합 사이의 중심점 개념을 결합한다. 우리는 제안한 유사척도에 대한 세 가지 속성도 증명한다. 제안한 방법은 구간값 모호집합 사이의 유사정도를 측정하는 유용한 방법을 제공한다.
In this paper, a similarity measure between interval-valued vague sets is proposed. In the interval-valued vague sets representation, the upper bound and the lower bound of a vague set are represented as intervals of interval-valued fuzzy set respectively. Proposed method combines the concept of geometric distance and the center-of-gravity point of interval-valued vague set to evaluate the degree of similarity between interval-valued vague sets. We also prove three properties of the proposed similarity measure. It provides a useful way to measure the degree of similarity between interval-valued vague sets.
