A hybrid iterated local search for solving a particular two-stage fixed-charge transportation problem

Abstract

In the current paper we take a different approach to a particular capacitated two-stage fixed-charge transportation problem proposing an efficient hybrid Iterated Local Search (HILS) procedure as a means of solving the above-mentioned problem. Our approach is a heuristic one; it constructs an initial solution while using a local search procedure whose aim is to increase the exploration, namely a perturbation mechanism. For the purpose of diversifying the search, a neighborhood structure is used to hybridize it. The preliminary computational results that we achieved stand as proof to the fact that the solution we propose yields high-quality solutions within reasonable running-times.
