Gauss-type integral inequalities for interval and fuzzy-interval-valued functions

Abstract

This study presents new Gauss's inequalities for interval and fuzzy-interval-valued functions using the Aumann's and Kaleva's improper integrals. The inequality for interval-valued functions is based on the Kulisch-Miranker order relation. The order relation given in the fuzzy-interval space is defined level-wise through the Kulisch-Miranker order, and by means of this the inequality for fuzzy-interval-valued functions is interpreted.
