The k-dissimilar vehicle routing problem
In this paper we define a new problem, the aim of which is to find a set of k dissimilar solutions for a vehicle routing problem (VRP) on a single instance. This problem has several practical applications in the cashin-transit sector and in the transportation of hazardous materials. A min–max mathematical formulation is proposed which requires a maximum similarity threshold between VRP solution...

متن کاملThe Special Application of Vehicle Routing Problem with Uncertainty Travel Times: Locomotive Routing Problem
This paper aims to study the locomotive routing problem (LRP) which is one of the most important problems in railroad scheduling in view of involving expensive assets and high cost of operating locomotives. This problem is assigning a fleet of locomotives to a network of trains to provide sufficient power to pull them from their origins to destinations by satisfying a rich set of operational con...
متن کاملThe Very Offline k-Vehicle Routing Problem in Trees
The vehicle routing problem (VRP) in trees is a restriction of the general vehicle routing problem in which the underlying graph is a tree. In this paper, we introduce several NP-complete variants of the problem (e.g., common-source, common-destinations, in-place, flexiblerequests, and bring-it-back), and we present five fast approximation algorithms for these variants. We mainly focus on the 2...
متن کاملVehicle Routing Problem: Meta-heuristic Approaches
The purpose of this article is to review the literature on the topic of deterministic vehicle routing problem (VRP) and to give a review on the exact and approximate solution techniques. More specifically the approximate (meta-heuristic) solution techniques are classified into: tabu search, simulated annealing, genetic algorithm, evolutionary algorithm, hybrid algorithm, and Ant Colony Opti...
