Title: Minimizing Greenhouse Emissions in Vehicle Routing
The Vehicle Routing Problem holds a central place in distribution management. In the classical version of the problem the aim is to distribute goods to a set of geographically dispersed customers under a cost minimization objective and various side constraints. In recent years a number of researchers have started investigating the joint minimization of cost and greenhouse emissions in vehicle routing, giving rise to the so-called “Pollution-Routing Problem”. Whereas cost depends primarily on distance travelled, emissions are a function of distance, vehicle load, speed and a variety of other factors. The aim of this talk is to describe recent research results in this context.
