SOME APPLICATIONS OF INTERVAL-VALUED SUBSETHOOD MEASURES WHICH ARE DEFINED BY INTERVAL-VALUED CHOQUET INTEGRALS IN TRADE EXPORTS BETWEEN KOREA AND ITS TRADING PARTNERS

Abstract

In this paper, we consider subsethood measures introduced by Fan et al. [3] and the interval-valued Choquet integral with respect to a fuzzy measure of interval-valued fuzzy sets. Based on such a focus, we define three types of interval-valued subsethood
measures and provide four interval-valued fuzzy sets to animal product exports between Korea and four selected trading partners. In particular, we investigate a strong interval-valued subsethood measure defined by the interval-valued Choquet integral which represents the degree of trade surplus between Korea and three trading partners in terms of the model of trade transactions with the United States and Korea
