An Interactive Biobjective Method for Solving a Waste Collection Problem

Abstract

The aim of this paper is to propose a framework in order to solve the real-world waste collection problem in a city of southern Spain modeled as an Asymmetric Vehicle Routing Problem (AVRP) with side constraints and several variations. In this problem, not only are vehicle capacity and temporal constraints considered but multiple trips are also allowed. Furthermore, two objectives will be considered: the minimization of the total distance and the balance of the working day. Finally, in order to select a single solution among all efficient (or nondominated) solutions, an interactive method is designed using reference points.

Transportation Risk Control of Waste Disposal in the Healthcare System with Two-Echelon Waste Collection Network

“…ere are some works of VRP in the healthcare system; for example, Veenstra et al [2] investigate the facility location problem and VRP arises in home delivery of medication in healthcare logistics. More works devoted to the collection of other wastes [3]. Among the numerous types of VRP , VRP with time windows and capacitated VRP have been widely investigated by the previous research [4][5][6].…”
