The traditional supply chain structure has been transformed into a combination of reverse logistics closed-loop supply chain architecture. Thus, green supply chain is addressed. Companies must to consider how to effectively coordinate the supply of each plant and face the global demands by using production planning strategies in such environment. This paper presents the integrated green (closed-loop) supply chain model considering logistics network, capacity, inventory, and raw materials selection (new or second-hand). A multi-objective mixed integer programming (MOMIP) model that involves the tradeoffs between economic and environmental perspectives under the total operating cost and the carbon dioxide (CO2) emission strategies is developed. In the numerical evaluation and results, we analyzed the relationship between the total cost and carbon emission in the integrated supply chain network by Pareto-optimal front.
Finally, the proposed MOMIP model is applied in a crystalline silicon solar energy industry to illustrate the efficiency and advantage for the production planning in the green supply chain in practice. Experimental results shows that the single-plant carbon reduction strategy for the overall supply chain. Which influences also reveal the cost of procurement, selection of first-hand materials and secondary materials in different combinations as well, and then decided to recycle used products disassembled degree of reduction.
