In order to design efficient logistics networks, a lot of approaches are proposed especially in the OR discipline. And quite a few companies apply these methods when making decision on designing real-world logistics networks. For most conventional methods, the optimization objective is minimizing logistics cost which is defined by cargo volume handled and cost conversion factors different form cargo characteristics (e.g. product category, size). Also, capacity of distribution centers (DCs) is represented by capacity factors. Meanwhile setting values on these factors are difficult realistically because real-world logistics are realized by utilizing various operational resources, and capacity and cost should be determined by the amount of resources used for logistics operation. In this paper, we have developed a logistics network design model including resource elements of logistics to represent real-world conditions. Implementing the model, we made computational experiments varying parameters and analyzed the features of obtained logistics networks.
