In the supply chain, producers try to plan their raw materials and final products with the production and delivery system for control of their flow, and this planning has to start from the purchase of the raw material for production to the delivery stage. Supply chain management and optimization is a promising aspect of enterprises and an exiting research area. Recently, there is a growing interest in supply chain design due to environmental impacts. It has become a necessity for the study to consider in the costs of transportation, the factor of environmental costs as social costs. In this paper, a new mixed integer mathematical model for a supply chain system is proposed. The chain system consists of two echelons and includes six suppliers, six manufacturers and six customer zones with six time period. The developed and proposed model provides the optimal values of transportation amounts of the purchased, manufactured and delivered raw material, while solving the location problem of each actor. We consider different trucks used for transporting according to their rental fees and COemission amounts. Also, we integrate a constraint of COemission quota into the supply chain as an environmental impact. The proposed model is validated by using hypothetical data and the results are discussed.
