Abstract
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 CO 2 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.
