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 ...

Exact algorithms for the clustered vehicle routing problem [PDF]
, 2014 This study presents new exact algorithms for the Clustered Vehicle Routing Problem (CluVRP). The CluVRP is a generalization of the Capacitated Vehicle Routing Problem (CVRP), in which the customers are grouped into clusters.

Local Area Routes for Vehicle Routing Problems
CoRR, 2022 We consider an approach for improving the efficiency of column generation (CG) methods for solving vehicle routing problems. We introduce Local Area (LA) route relaxations, an alternative/complement to the commonly used ng-route relaxations and Decremental State Space Relaxations (DSSR) inside of CG formulations. LA routes are a subset of ng-routes and

The Vehicle Routing Problem with Partial Outsourcing [PDF]
Transportation Science, 2020 This paper introduces the vehicle routing problem with partial outsourcing (VRPPO) in which a customer can be served by a single private vehicle, by a common carrier, or by both a single private vehicle and a common carrier. As such, it is a variant of the vehicle routing problem with private fleet and common carrier (VRPPC).

The Fleet Size and Mix vehicle Routing Problem with backhauls: Formulation and Set partitioning-based heuristics [PDF]
, 2013 In this paper we present a new variant of the classical Vehicle Routing Problem – the Fleet Size and Mix Vehicle Routing Problem with Backhauls (FSMVRPB). An ILP formulation of the FSMVRPB is presented.

To the classification of vehicles routing problems
Науковий вісник Ужгородського університету. Серія: Математика і інформатика, 2020 The essence of the problems considered consists in developing routes for a group of heterogeneous vehicles based in a specific place or places (depot) that have to deliver goods to customers according to their volume of orders.

Vehicle Routing Problem Models
Promet (Zagreb), 2004 The Vehicle Routing Problem cannot always be solved exactly,so that in actual application this problem is solved heuristically.The work describes the concept of several concrete VRPmodels with simplified initial conditions (all vehicles are ofequal ...
