Bilevel optimization problems are hierarchical optimization problems where the feasible
region of the so-called upper level problem is restricted by the graph of the solution set …

This study presents bi-level decision making model for the management of municipal solid
wastes (MSW). The model starts with waste disposals by the people, followed by its …

Bi-level programming problem (BLPP) is an optimization problem consists of two
interconnected hierarchical optimization problems. Solving BLPP is one of the hardest tasks …

This paper deals with the modeling and optimization of a bi-level multi-objective production
planning problem, where some of the coefficients of objective functions and parameters of …

In this paper we addressed supply chain network (SCN) as bi-level programming problem in
which the primary objective is to determine optimal order allocation of products where the …

The purpose of this paper is to study variational inequality problem over the solution set of
multiple-set split monotone variational inclusion problem. We propose an iterative algorithm …

This research work seeks to model the distribution of 50 cl Pepsi soft drink as a transhipment
problem. The transshipment problem is an extension of the traditional transportation …

In this paper, we propose an enhanced genetic algorithm and chaos search for solving
bilevel programming problem (BLPP). Enhanced genetic algorithm based on new effective …

It is found that the simplex algorithm is immensely used and proficient algorithm ever
invented and shown extremely accurate in the formulation of optimization problems. In this …

Present article shows an attempt which deals to explain goal programming by using
Modified Charnes Penalty Method. Many times, this method involves less or at the most an …
