Abstract

In addition to fuzzy and stochastic theory, interval analysis is a powerful tool for solving uncertain problems. An important problem in interval analysis is the ranking of interval numbers. This paper analyzes the definitions of satisfaction index for comparing interval numbers. Sometimes different definitions of the satisfaction indices lead to confusion. The main result of the paper is to show that some existing definitions of the satisfaction index are equivalent.

Keywords
