International audienceTransportation is an important component of supply chain competitiveness since it plays a major role in the inbound, inter-facility, and outbound logistics. In this context, assigning and scheduling vehicle routing is a crucial management problem. Despite the existence of numerous publications dealing with efficient scheduling methods for vehicle routing, very few address the inherent stochastic nature of this problem. In this paper, a novel framework for modelling routing problems with time-dependent travel times due to potential traffic congestion is considered. The approach developed introduces mainly the traffic congestion component modelled through a queueing mode!. Standard test problems are used for illustrative...
