Toward characterizing solutions to complex programming problems involving fuzzy parameters in constraints [PDF]

International Journal of Research in Industrial Engineering
The current study investigates to characterize the Complex Programming Problem (CPP) solution in a fuzzy environment. The paper is divided into two parts: 1) the first presents a Fuzzy Complex Programming Problem (F-CPP) with fuzzy complex constraints ...

Classification of Complex Fuzzy Numbers and Fuzzy Inner Products

Mathematics, 2020
The paper is concerned with complex fuzzy numbers and complex fuzzy inner product spaces. In the classical complex number set, a complex number can be expressed using the Cartesian form or polar form. Both expressions are needed because one expression is

A New Approach of Complex Fuzzy Ideals in BCK/BCI-Algebras

Mathematics
The concept of complex fuzzy sets, where the unit disk of the complex plane acts as the codomain of the membership function, as an extension of fuzzy sets. The objective of this article is to use complex fuzzy sets in BCK/BCI-algebras.
