Heterogeneous Fleet Vehicle Routing Problem with Selec-tion of Inter-Depots

Abstract

The paper presents heterogeneous fleet vehicle routing problem with selection of inter-depots. The goal of the proposed model is to schedule shipments of goods from the central depot to the inter-depots and finally to the endpoint customers, so that as inter-depots are considered the existing capacities of endpoints customers. In given type of transportation it can be expected to use two types of vehicles: large capacity vehicles ensuring the distribution of goods from the central warehouse and small capacity vehicles ensuring the delivery of goods from inter-depots for late shipment to other cus-tomers. The principle of the model is illustrated on three demonstrative instances.
