A Multi-Objective Mathematical Model for Green Supply Chain Reorganization

This study considers a green supply chain design (GrSC) with environmental concerns. We develop a multi-objective mathematical mode for hub location allocation problem that captures the trade-off between our objectives. The first objective is related to the total cost: transportation & inventory cost and the second one is related to the environment impact, such as CO2 emission. The strategic decisions considered in the proposed model define which warehouses should be selected as a distribution center (hub) and what transportation mode and organization which number of vehicles are required to move products in each period among suppliers, distribution center and warehouses. a new resolution process is proposed and meta-heuristic approach is applied to obtain Pareto frontier.
