Recent Advances in Vehicle Routing with Stochastic Demands: Bayesian Learning for Correlated Demands and Elementary Branch-Price-and-Cut
Alexandre M. Florio, Michel Gendreau, Richard F. Hartl +2
We consider the vehicle routing problem with stochastic demands (VRPSD), a stochastic variant of the well-known VRP in which demands are only revealed upon arrival of the vehicle a…
An efficient bundle-based approach for the share-a-ride problem
Ana Beatriz Herthel, Richard Hartl, Anand Subramanian +1
Some of today's most significant challenges in urban environments concern individual mobility and rapid parcel delivery. With the surge of e-commerce and the ever-increasing volume…
New Exact Algorithm and Solution Properties for the Vehicle Routing Problem with Stochastic Demands
Alexandre Florio, Richard Hartl, Stefan Minner
This paper considers the vehicle routing problem with stochastic demands (VRPSD) under optimal restocking. We develop an exact algorithm that is effective for solving instances wit…
Workload Equity in Vehicle Routing: The Impact of Alternative Workload Resources
Piotr Matl, Richard F. Hartl, Thibaut Vidal
In practical vehicle routing problems (VRPs), important non-monetary benefits can be achieved with more balanced operational plans which explicitly consider workload equity. This h…
The Electric Two-echelon Vehicle Routing Problem
Ulrich Breunig, Roberto Baldacci, Richard F. Hartl +1
Two-echelon distribution systems are attractive from an economical standpoint and help to keep large vehicles out of city centers. Large trucks can be used to deliver goods to inte…
Large Neighborhood-Based Metaheuristic and Branch-and-Price for the Pickup and Delivery Problem with Split Loads
Matheus Nohra Haddad, Rafael Martinelli, Thibaut Vidal +4
We consider the multi-vehicle one-to-one pickup and delivery problem with split loads, a NP-hard problem linked with a variety of applications for bulk product transportation, bike…
Collaborative vehicle routing: a survey
Margaretha Gansterer, Richard F. Hartl
In horizontal collaborations, carriers form coalitions in order to perform parts of their logistics operations jointly. By exchanging transportation requests among each other, they…
Heuristic Rectangle Splitting: Leveraging Single-Objective Heuristics to Efficiently Solve Multi-Objective Problems
Piotr Matl, Richard F. Hartl, Thibaut Vidal
Real-life problems are often characterized by conflicting optimization objectives. Consequently, there has been a growing interest not only in multi-objective models, but also in s…
Capacity Planning for Cluster Tools in the Semiconductor Industry
Martin Romauch, Richard F. Hartl
This paper proposes a new model for Cluster-tools with two load locks. Cluster-tools are widely used to automate single wafer processing in semiconductor industry. The load locks a…
Workload Equity in Vehicle Routing Problems: A Survey and Analysis
Piotr Matl, Richard F. Hartl, Thibaut Vidal
Over the past two decades, equity aspects have been considered in a growing number of models and methods for vehicle routing problems (VRPs). Equity concerns most often relate to f…
The lateral transhipment problem with a-priori routes, and a lot sizing application
Martin Romauch, Thibaut Vidal, Richard F. Hartl
We propose exact solution approaches for a lateral transhipment problem which, given a pre-specified sequence of customers, seeks an optimal inventory redistribution plan consideri…
A large neighbourhood based heuristic for two-echelon routing problems
Ulrich Breunig, Verena Schmid, Richard F. Hartl +1
In this paper, we address two optimisation problems arising in the context of city logistics and two-level transportation systems. The two-echelon vehicle routing problem and the t…
