Interior Point Method for Solving Fuzzy Number Linear Programming Problems Using Linear Ranking Function

Interior Point Method for Solving Fuzzy Number Linear Programming Problems Using Linear Ranking Function

Recently, various methods have been developed for solving linear programming problems with fuzzy number, such as simplex method and dual simplexmethod. But their computational complexities are exponential, which is not satisfactory for solving largescale fuzzy linear programming problems, especially in the engineering field. A new method which can solve large-scale fuzzy number linear programmi...

Defuzzification Method for Solving ‎Fuzzy ‎Linear Programming Problems

Several authors have proposed different methods to find the solution of fully fuzzy linear programming (FFLP) problems. But all the existing methods are based on the assumption that all the fuzzy coefficients and the fuzzy variables are non-negative fuzzy numbers. in this paper a new method is proposed to solve an FFLP problems with arbitrary fuzzy coefficients and arbitrary fuzzy variables, th...

Solving Fully Fuzzy Linear Programming Problems with Zero-One Variables by Ranking Function

Jahanshahloo has suggested a method for the solving linear programming problems with zero-one variables‎. ‎In this paper we formulate fully fuzzy linear programming problems with zero-one variables and a method for solving these problems is presented using the ranking function and also the branch and bound method along with an example is presented.

SOLVING FUZZY LINEAR PROGRAMMING PROBLEMS WITH LINEAR MEMBERSHIP FUNCTIONS-REVISITED

Recently, Gasimov and Yenilmez proposed an approach for solving two kinds of fuzzy linear programming (FLP) problems. Through the approach, each FLP problem is first defuzzified into an equivalent crisp problem which is non-linear and even non-convex. Then, the crisp problem is solved by the use of the modified subgradient method. In this paper we will have another look at the earlier defuzzifi...
