A compromise solution for the neutrosophic multi-objective linear programming problem and its application in transportation problem
Articles in Press, Accepted Manuscript, Available Online from 19 June 2022
Abstract
Neutrosophic set theory plays an important role in dealing with the impreciseness and inconsistency in data encountered in solving real-life problems. The current paper focuses on the neutrosophic fuzzy multiobjective linear programming problem (NFMOLPP), where the coefficients of the objective functions, ...

Volume 8, Issue 3 , September 2021, , Pages 251-269
Abstract
The aim of this paper is to introduce a formulation of fully fuzzy transportation problems involving pentagonal and hexagonal fuzzy numbers for the transportation costs and values of supplies and demands. We introduce new technique for improve methods for solving the fully fuzzy transportation ... Read MoreA nonlinear approach for neutrosophic linear programming
Volume 6, Issue 4 , December 2019, , Pages 367-373
Abstract
Traditional linearl programming usually handles optimization problems involving deterministic objective functions and/or constrained functions. However, uncertainty also exists in real problems. Hence, many researchers have proposed uncertain optimization methods, such as approaches using fuzzy and stochastic ... Read MoreA new approach to solve fully fuzzy linear programming problem
Volume 6, Issue 2 , June 2019, , Pages 139-149
Abstract
Today, human decisions are more than ever based on information. But most of this information is not definitive, and in this situation, logical decision making is very difficult based on this uncertainty. Different methods are used to represent this uncertainty, including the fuzzy numbers. The fuzzy ...

Volume 5, Issue 3 , November 2018, , Pages 239-252
Abstract
In this paper, a Multi-Criteria De Novo Linear Programming (F- MDNLP) problem has been developed under consideration of the ambiguity of parameters. These fuzzy parameters are characterized by fuzzy numbers. A fuzzy goal programming approach is applied for the corresponding multi-criteria De Novo linear ...

Volume 5, Issue 2 , September 2018, , Pages 110-121
Abstract
In this paper, a Fuzzy Multi-Objective Linear Programming (FMOLP) problem having both objective functions and constraints fuzzy parameters is introduced. Theses fuzzy parameters are characterized by trapezoidal fuzzy numbers. The FMOLP problem is converted into the corresponding deterministic MOLP problem ... Read MoreA Solution Approach for Solving Fully Fuzzy Quadratic Programming Problems
Volume 5, Issue 1 , June 2018, , Pages 50-61
Abstract
Quadratic Programming has been widely applied to solve real-world problems. This paper describes a solution method for solving a special class of fuzzy quadratic programming problems with fuzziness in relations. Then the method is generalized to a more general fuzzy quadratic programming problem, where ... Read MoreA new model for solving fuzzy linear fractional programming problem with ranking function
Volume 4, Issue 2 , October 2017, , Pages 89-96
Abstract
In this paper, we studied fuzzy linear fractional programming (FLFP) problems with trapezoidal fuzzy numbers where the objective functions are fuzzy numbers and the constraints are real numbers. In this study, in order to obtain the fuzzy optimal solution with unrestricted variables and parameters, a ...

Volume 4, Issue 2 , October 2017, , Pages 97-115
Abstract
In this paper, dynamic programming for sequencing weighted jobs on a single machine to minimizing total tardiness is focused, to significance of fuzzy numbers field, and importance of that for decision makers who are facing on uncertain data, combination of dynamic programming and fuzzy numbers is applied. ...

Volume 4, Issue 1 , September 2017, , Pages 1-7
Abstract
In traditional shortest path problem it is always determined that the parameters (Time, Cost and Distance etc.) are fixed between different nodes. But in real life situations where uncertain parameters exist, parameters are considered as fuzzy numbers. In this paper, we explained the application ...
