Stimulated by the growing demand for logistics services and the advances in information
technologies, research interest in the dynamic vehicle routing problem with random requests …

In recent years, many important real-world applications are studied as “rich” vehicle routing
problems that are variants and generalizations of the well-known vehicle routing problem. In …

Recently, electric vehicles have become a viable option for city logistics to reduce air
pollution and operating noise. In this study we consider the pickup and delivery problem with …

Dedicated algorithm and modeling improvements continue to advance the state of the art
with respect to vehicle routing problems (VRPs). Despite these academic achievements …

This article considers a setting in which a courier, express, and parcel service provider
operates a fleet of vehicles with regular drivers (RDs) to ship parcels from pickup to delivery …

Collaborative transportation planning (CTP) within a coalition of small and medium-sized
