Abstract

Memetic algorithm for multi-tours dynamic vehicle routing problem with overtime (MDVRPOT)

Highlights

  • Dantzig and Ramser (1959) introduced a wide class of problems, the objective of which is to determine the best roads linking two or more points under certain constraints

  • The results obtained by applying the memetic algorithm (MA) to the instances presented by Kilby et al (1998) are presented to assess its performance based on the classical dynamic vehicle routing problem (DVRP)

  • The results obtained by applying the MA to the instances of Ouaddi et al (2018) and those obtained by the ant colony system (ACS) of the same study (Ouaddi et al, 2018) are compared

Summary

Introduction

Dantzig and Ramser (1959) introduced a wide class of problems, the objective of which is to determine the best roads linking two or more points under certain constraints. Many researchers have studied different possible variants of this problem. These variants are defined depending on the nature, constraints, and objectives of the problem. The objective is to determine the optimal set of routes that should deliver to a set of customers from a single depot with a limited fleet of trucks with limited capacities. These customers have varying demands for the same products. Golden et al (1977) introduced the term ‘vehicle routing’ and called this variant ‘the generic vehicle routing problem’ (VRP). Researchers have defined and treated a large number of VRPs according to the demands of the transport market and ability of the technological context (Eksioglu et al (2009))
