Solving Fuzzy Linear Programming Problems Using Two-Level Programming Approach
H. A. Khalifa Department of Operations Research, Institute of Statistical Studies and Research, Cairo University, Cairo, Egypt. Abstract Linear programming (LP) has been widely applied to solving real world problems. The conventional LP model requires the parameters to be known constants. In the real world, however, the parameters are seldom known exactly and have to be estimated. This paper de...
متن کاملInteractive Fuzzy Programming for Multiobjective Two-level Nonlinear Integer Programming Problems through Genetic Algorithms
In the present paper, we consider multiobjective two-level nonlinear integer programming problems (MOTLNLIPPs) in which the decision maker (DM) at each level controls his own integer decision variables to optimize multiple objective functions. Various approaches for multi-level programming problems could exist according to situations which the DMs are placed in. In this paper, it is assumed tha...
متن کاملSolving multiobjective linear programming problems using ball center of polytopes
Here, we aim to develop a new algorithm for solving a multiobjective linear programming problem. The algorithm is to obtain a solution which approximately meets the decision maker's preferences. It is proved that the proposed algorithm always converges to a weak efficient solution and at times converges to an efficient solution. Numerical examples and a simulation study are used to illu...
متن کاملA 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...
متن کاملInteractive fuzzy programming for stochastic two-level linear programming problems through probability maximization
This paper considers two-level linear programming problems involving random variable coefficients both in objective functions and constraints. Using the concept of chance constraints, under some appropriate assumptions for distribution functions, the original stochastic two-level linear programming problems are transformed into deterministic ones. Taking into account vagueness of judgments of t...
