This paper presents a column generation heuristic for the general vehicle routing problem (GVRP), a combined load acceptance and rich vehicle routing problem incorporating various ...
We present a unified heuristic, which is able to solve five different variants of the vehicle routing problem: the vehicle routing problem with time windows (VRPTW), the capacit...
The Vehicle Routing Problem with Time Windows (VRPTW) is an important problem in logistics. The problem is to serve a number of customers at minimum cost without violating the cus...
In the paper we address the Distance-Constrained Capacitated Vehicle Routing Problem (DCVRP), where k minimum-cost routes through a central depot have to be constructed so as to co...
