Analyzing combined vehicle routing and break scheduling from a distributed decision making perspective [PDF]

, 2009
We analyze the problem of combined vehicle routing and break scheduling from a distributed decision making perspective. The problem of combined vehicle routing and break scheduling can be defined as the problem of finding vehicle routes to serve a set of

Optimal Routing of Energy-aware Vehicles in Networks with Inhomogeneous Charging Nodes

, 2014
We study the routing problem for vehicles with limited energy through a network of inhomogeneous charging nodes. This is substantially more complicated than the homogeneous node case studied in [1]. We seek to minimize the total elapsed time for vehicles

A dynamic approach for the vehicle routing problem with stochastic demands [PDF]

, 2011
The Vehicle Routing Problem with Stochastic Demands (VRPSD) is a variation of the classical Capacitated Vehicle Routing Problem (CVRP). In contrast to the deterministic CVRP, in the VRPSD the demand of each customer is modeled as a random variable and ...
