This paper introduces a new bi-objective vehicle routing problem that integrates the Open Location Routing Problem (OLRP), recently presented in the literature, coupled with the growing need for fuel consumption minimization, ...

The capacitated location routing problem (CLRP) integrates a facility location problem with a multi-depot vehicle routing problem. We consider the CLRP with stochastic demands, whose specific values are only revealed upon ...

In this paper we formulate an integer programming model for the Location and Routing Problem with Pickup and Delivery. We propose a column generation scheme and implement, for the subproblem, a label-setting algorithm for ...

We consider the Location-Routing Problem with Heterogeneous Fleet (LRPH) in which the goal is to determine the depots to be opened, the customers to be assigned to each open depot, and the corresponding routes fulfilling ...

Abstract: In the context of city logistics, freight transportation is one of the prominent causes of traffic congestion, high levels of pollution, and safety concerns. To decrease the negative impact of these issues, ...

The location routing problem integrates both a facility location and a vehicle routing problem. Each of these problems are NP-hard in nature, which justifies the use of heuristic-based algorithms when dealing with large-scale ...

During the last decade, e-commerce has increased last-mile deliveries, impacting the (CO2) emissions footprint. Considering this environmental impact, sustainable technologies have emerged for transport operations, e.g., ...

The location routing problem (LRP) involves the three key decision levels in supply chain design, that is,strategic, tactical, and operational levels. It deals with the simultaneous decisions of (a) locating facilities(e.g., ...

Resolver el problema de localización y ruteo de inventarios optimiza simultáneamente el diseño de la cadena de suministro y sus costos operacionales. Los supuestos del modelo incluyen el hecho que los vehículos pueden ...
