A signed distance for (γ,δ) interval-valued fuzzy numbers to solve multi objective assignment problems with fuzzy parameters
Volume 11, Issue 2 , June 2022, , Pages 205-213
Abstract
In this paper, a multi-objective assignment problem with fuzzy parameters (FMOASP) is introduced. These fuzzy parameters are characterized by an interval-valued fuzzy numbers instead of fuzzy numbers. The signed distance ranking of interval- valued fuzzy numbers of the parameters are not ...

Volume 10, Issue 3 , September 2021, , Pages 251-275
Abstract
The aim of this paper is to introduce a new technique for improve the methods for solving the Semi-fully Fuzzy Linear Programming Problems. An algorithm is proposed to find the fuzzy optimal solution of Semi-fully Fuzzy Linear Programming Problems. This technique is also best fuzzy optimal solution in ...

Volume 8, Issue 2 , June 2019, , Pages 158-175
Abstract
In many real applications, the data of production processes cannot be precisely measured. Hence the input and output of Decision Making Units (DMUs) in Data Envelopment Analysis (DEA) may be imprecise or fuzzy-numbered. In original DEA models, inputs and outputs are measured by exact values on a ratio ... Read MoreModified Method for Solving Fully Fuzzy Linear Programming Problem with Triangular Fuzzy Numbers
Volume 6, Issue 4 , December 2017, , Pages 293-311
Abstract
The Fuzzy Linear Programming problem has been used as an important planning tool for the different disciplines such as engineering, business, finance, economics, etc. In this paper, we proposed a modified algorithm to find the fuzzy optimal solution of fully fuzzy linear programming problems with equality ...

Volume 6, Issue 3 , November 2017, , Pages 214-227
Abstract
Supplier selection is one of the most critical activities of purchasing management in a supply chain. Because selecting right suppliers helps reduce purchasing costs, improve quality of final products and services, etc. In a real situation, for a supplier selection problem, most of the input information ... Read MoreOrganizational Performance Evaluation Considering Human Capital Management Approach by Fuzzy-DEA: A Case Study
Volume 6, Issue 1 , March 2017, , Pages 1-16
Abstract
In recent years, researchers in their studies considered human capital as one of the most important capitals of every organization and even some of them placed it beyond this definition and introduced it as the unique factor of creating the competitive advantage in the organization. Due to the importance ... Read MoreFailure Modes and Effects Analysis under Fuzzy Environment Using Fuzzy Axiomatic Design Approach
