Towards improved trapezoidal approximation to intersection (fusion) of trapezoidal fuzzy numbers: Specific procedure and general non-associativity theorem

Abstract: In some cases, our uncertainty about a quantity can be described by an interval of its possible values. If we have two or more pieces of interval information about the same quantity, then we ...

ABSTRACT: In this paper, we introduce a method to obtain the nearest trapezoidal approximation of fuzzy numbers so that preserving conditions expect interval and include the core of a fuzzy number.

Trapezoidal approximations by preserving the interval-valued possibilistic mean of fuzzy numbers with restrictions on support and core

Abstract: By adding two supplementary constraint conditions on the support and core, we present a new approach to obtain trapezoidal approximation of a fuzzy number by preserving the interval-valued ...
