A Genetic Algorithm of Two-stage Supply Chain Distribution Problem Associated with Fixed Charge and Multiple Transportation Modes

摘要

A two-stage fixed charge distribution problem associated with multiple transportation modes selection of a supply chain is presented, two kinds of transportation cost and one kind of transshipment cost are involved in: a continuous cost that linearly increases with the amount transported between a source and a destination, and secondly, a fixed charge, that incurs whenever there exists a transportation of a non-zero quantity between a source and a destination, Thirdly, a transshipment cost, incurs whenever there exists a transshipment in the distribution centers (DCs). A genetic algorithm of this problem is designed and applied; a numerical example reveals that the GA can obtain good solution of the problem effective.
