S. K. Das; J. K. Dash

Volume 9, Issue 1 , Winter 2020, , Pages 13-24

http://dx.doi.org/10.22105/riej.2020.224198.1127

Abstract
  Neutrosophic Linear Programming (NLP) issues is presently extensive applications in science and engineering. The primary commitment right now to manage the NLP problem where the coefficients are neutrosophic triangular numbers with blended requirements. The current method [20] are viewed as just imbalance ...  Read More

2. A new method for solving fuzzy linear fractional programming problem with new ranking function

S. Kumar-Das

Volume 8, Issue 4 , Autumn 2019, , Pages 384-393

http://dx.doi.org/10.22105/riej.2020.220850.1123

Abstract
  Because of uncertainty in the real life applications, reaching to the optimal solution is always time consuming and even sometimes impossible. In order to overcome these limitations the fuzzy set theory is introduced to handle it but not only incomplete information but also indeterminate and inconsistent ...  Read More

4. A MOLFP Method for Solving Linear Fractional Programming Under Fuzzy Environment

S.K. Das; T. Mandal

Volume 6, Issue 3 , Autumn 2017, , Pages 202-213

http://dx.doi.org/10.22105/riej.2017.92950.1002

Abstract
  In this paper, a solution procedure is proposed to solve Fully Fuzzy Linear Fractional Programming (FFLFP) problem where all the variables and parameters are triangular fuzzy numbers. Here, FFLFP problem transformed into an equivalent Multi- Objective Linear Fractional Programming (MOLFP) problem. Then ...  Read More
