Bi-objective Optimization of Logistic Networks with Full-Connectivity Structure Using NSGA-II

Przemysław Ignaciuk and Łukasz Wieczorek

Abstract—This paper addresses the resource control issue in goods distribution networks. Two types of actors—suppliers and warehouses—are linked without topological restrictions. The interconnection structure in the discussed class of logistic networks forms a mesh-type topology. During the distribution process, the warehouses face external demands, not known a priori. The flow of goods in the system is governed according to the networked order-up-to (NOUT) inventory management policy implemented in a centralized manner. The balance between the customer service level and the holding cost poses a bi-objective optimization challenge. The novelty of this paper is an application of the nondominated sorting genetic algorithm II to adjust the NOUT policy to the logistic problem under consideration. Numerical studies performed for various topologies and distribution structures have asserted the efficiency of the discussed method.

Index Terms—Logistic networks, genetic algorithms, multi-objective optimization, uncertain demand, inventory management.
