Abstract This paper presents an exact method for two important generalizations of the classical Capacitated Vehicle Routing problem (CVRP): the Period Vehicle Routing Problem (PVRP) and the Multi-Depot Vehicle Routing Problem (MDVRP).The VRP is defined on a graph G=(V, A), where V={0,1,...
Deep Reinforcement Learning for Solving the Vehicle Routing ProblemMohammadreza Nazari, 1 Afshin Oroojlooy, 1 Lawrence V. Snyder, 1 Martin Takᡠc 1AbstractWe present an end-to-end framework for solvingVehicle Routing Problem (VRP) using deep re-inforcement learning. In this approach, we tra...

the Vehicle Routing Problem (VRP) calls for the determination of the optimal set of routes to be performed by a fleet of vehicles, in order to satisfy the demand of a given set of customers. Several important variants of this basic problem were extensively studied in the literature (see,...

In this article, the real-time time-dependent vehicle routing problem with time windows is formulated as a series of mixed integer programming models that account for real-time and time-dependent travel times, as well as for real-time demands in a unified framework. In addition to vehicles rou...
Local search has been established as a successful cornerstone to tackle the Vehicle Routing Problem, and is included in many state-of-the-art heuristics. In this paper we aim to demonstrate that a well-implemented local search on its own suffices to create a heuristic that computes high-qualit...
The usual static version, namely Vehicle Routing Problem with Time Windows (VRPTW) includes capacity and time window constraints. In the VRPTW, a fleet of identical vehicles supplies goods to N customers. All vehicles have the same capacity Q. For each customer i, i = 1,…,N, the demand ...
