Two-stage stochastic and robust green location-routing problem

open access: yesCleaner Logistics and Supply Chain
As urbanization increases, low–pollution freight delivery is crucial, while customer demand is often uncertain. For these reasons, this paper introduces a new mixed-integer mathematical model for the two-stage stochastic green location-routing problem ...

The Vehicle Routing Problem with Divisible Deliveries and Pickups [PDF]

open access: yes, 2012
The vehicle routing problem with divisible deliveries and pickups is a new and interesting model within reverse logistics. Each customer may have a pickup and delivery demand that have to be served with capacitated vehicles. The pickup and the delivery

[Retracted] The HSABA for Emergency Location‐Routing Problem

open access: yesMathematical Problems in Engineering, 2019
This article presents a Location‐Routing Problem (LRP) model to assist decision makers in emergency logistics. The model attempts to consider the relationship between the location of warehouses and the delivery routes in order to maximize the rescue efficiency.

Lagrangian relaxation heuristics for the uncapacitated single-source multi-product facility location problem [PDF]

open access: yes, 2013
Facility location problem is one of the strategic logistical drivers within the supply chain which is a hard to solve optimization problem. In this study, we focus on the uncapacitated single-source multi-product production/distribution facility location

Heuristic algorithms for the Capacitated Location-Routing Problem and the Multi-Depot Vehicle Routing Problem [PDF]

open access: yes, 2013
The Capacitated Location-Routing Problem (CLRP) is a NP-hard problem since it generalizes two well known NP-hard problems: the Capacitated Facility Location Problem (CFLP) and the Capacitated Vehicle Routing Problem (CVRP).
