Stochastic Vehicle Routing with Recourse [PDF]
, 2012 We study the classic Vehicle Routing Problem in the setting of stochastic optimization with recourse. StochVRP is a two-stage optimization problem, where demand is satisfied using two routes: fixed and recourse.

Vehicle Routeing with Multiple Use of Vehicles [PDF]
Journal of the Operational Research Society, 1996 The vehicle routeing problem with multiple use of vehicles is a variant of the standard vehicle routeing problem in which the same vehicle may be assigned to several routes during a given planning period. A tabu search heuristic is developed for this problem. It is shown to produce high quality solutions on a series of test problems.

On the Selective Vehicle Routing Problem [PDF]
Mathematics, 2020 The Generalized Vehicle Routing Problem (GVRP) is an extension of the classical Vehicle Routing Problem (VRP), in which we are looking for an optimal set of delivery or collection routes from a given depot to a number of customers divided into predefined,

Hierarchical vehicle routing problems [PDF]
Networks, 1984 AbstractHierarchical vehicle routing problems, in which the decision to acquire a number of vehicles has to be based on imperfect (probabilistic) information about the location of future customers, allow a natural formulation as two‐stage stochastic programming problems, where the objective is to minimize the sum of the acquisition cost and the length ...

Vehicle routing with subtours [PDF]
Discrete Optimization, 2019 When delivering items to a set of destinations, one can save time and cost by passing a subset to a sub-contractor at any point en route. We consider a model where a set of items are initially loaded in one vehicle and should be distributed before a given deadline Δ.

Electric Vehicle Routing with Public Charging Stations
Transportation Science, 2021 We introduce the electric vehicle routing problem with public-private recharging strategy in which vehicles may recharge en route at public charging infrastructure as well as at a privately-owned depot.

Collaborative vehicle routing: A survey [PDF]
European Journal of Operational Research, 2018 In horizontal collaborations, carriers form coalitions in order to perform parts of their logistics operations jointly. By exchanging transportation requests among each other, they can operate more efficiently and in a more sustainable way. Collaborative vehicle routing has been extensively discussed in the literature.

Algorithms for Capacitated Vehicle Routing [PDF]
SIAM Journal on Computing, 2001 Given n identical objects (pegs), placed at arbitrary initial locations, we consider the problem of transporting them efficiently to n target locations (slots) with a vehicle that can carry at most k pegs at a time. This problem is referred to as k-delivery TSP, and it is a generalization of the traveling salesman problem.
