Abstract

Ordered fuzzy numbers are a very useful idea when we try to describe the real world in a natural human way. Terms such as “far or “near” are naturally understood by people. Properties of ordered fuzzy numbers make it possible to more accurately represent the natural human understanding of the world and convert this into a useful code understandable to computers. This article describes methods for fuzzification of real numbers to the model of ordered fuzzy numbers. The professional literature provides many order-sensitive functions for defuzzification of OFN numbers, but there are no fuzzification functions dedicated to OFN. The article puts forward theoretical backgrounds of ordered fuzzy numbers arithmetic and describes fuzzification functionals along with examples.
