Some Operational Computation for Intuitionistic or Pythagorean Fuzzy Set Using C-Programming

An integrated method using intuitionistic fuzzy set and linear programming for supplier selection problem

Supplier selection is one of the most important activities in supply chain management. Aim of this process is to find suppliers which have the most compatible specifications with buyer`s requirements. This study develops an integrated approach by applying intuitionistic fuzzy set and linear programming technique. It uses two indicators to explain supplier’s advantages and their flexibility for ...

SOME INTUITIONISTIC FUZZY CONGRUENCES

First, we introduce the concept of intuitionistic fuzzy group congruenceand we obtain the characterizations of intuitionistic fuzzy group congruenceson an inverse semigroup and a T^{*}-pure semigroup, respectively. Also,we study some properties of intuitionistic fuzzy group congruence. Next, weintroduce the notion of intuitionistic fuzzy semilattice congruence and we givethe characterization of...

Some Basic Operations on Pythagorean Fuzzy Sets

In this paper we present a short but important summary of Pythagorean fuzzy sets. Especially we discuss several basic and important definitions of Pythagorean fuzzy sets, several operations on Pythagorean fuzzy sets, several algebraic laws of Pythagorean fuzzy sets. In the last we also present the concept of modal operators and normalization on Pythagorean fuzzy sets.

SOME PROPERTIES FOR FUZZY CHANCE CONSTRAINED PROGRAMMING

Convexity theory and duality theory are important issues in math- ematical programming. Within the framework of credibility theory, this paper rst introduces the concept of convex fuzzy variables and some basic criteria. Furthermore, a convexity theorem for fuzzy chance constrained programming is proved by adding some convexity conditions on the objective and constraint functions. Finally,...
