An iterative method for tri-level quadratic fractional programming problems using fuzzy goal programming approach

Quadratic bi-level programming problems: a fuzzy goal programming approach

This paper presents a fuzzy goal programming (FGP) methodology for solving bi-level quadratic programming (BLQP) problems. In the FGP model formulation, firstly the objectives are transformed into fuzzy goals (membership functions) by means of assigning an aspiration level to each of them, and suitable membership function is defined for each objectives, and also the membership functions for vec...

A goal programming approach for fuzzy flexible linear programming problems

 We are concerned with solving Fuzzy Flexible Linear Programming (FFLP) problems. Even though, this model is very practical and is useful for many applications, but there are only a few methods for its situation. In most approaches proposed in the literature, the solution process needs at least, two phases where each phase needs to solve a linear programming problem. Here, we propose a method t...

Fuzzy Goal Programming Approach for Quadratic Fractional Bilevel Programming

This paper presents a fuzzy goal programming methodology for solving bilevel programming problems having quadratic fractional form of objectives of the decision makers. In the proposed procedure, the membership functions for the defined fuzzy goals of objective of the decision makers at both levels are developed first. Then a fuzzy goal programming model is developed to minimize the group regre...

Fractional CCP: A Fuzzy Goal Programming Approach

Abstract It is the purpose of this article to introduce a linear approximation technique for solving a fractional chance constrained programming (CC) problem. For this purpose, a fuzzy goal programming model of the equivalent deterministic form of the fractional chance constrained programming is provided and then the process of defuzzification and linearization of the problem is started. A sam...
