An Integrated Inventory Location Routing Problem Considering CO2 Emissions

Abstract

This paper considers an integrated Inventory Location Routing problem ILRP which consists of optimizing the operating costs, risks and routing‘s CO2 emissions related to a Hazmat supply chain. The goal is to determine: the location of a set of capacitated depots to open, customers allocated to them, quantities delivered from these depots to customers per period, and the sequence in which customers are served by a heterogeneous fleet of vehicles. To solve the problem, an exact bi-objective model is designed and tested for small and medium size instances. A case study is proposed to prove industrial practicality of the model. The results show that the proposed solution resolves decently the medium size instances.
