Abstract：Based on the color TV sets manufacturer as the focal company in the supply chain, this paper develops an environmental performance optimization model for a multitiered closed loop supply chain by means of life cycle assessment methodology from the ecological environment influence of the supply chain. And then this model is solved and simulated using MATLAB. According to the simulating results of the model, the manufacturer can know how to select suppliers and recycling treatments so that the environmental performance will be optimized from the entire supply chain, and further more, the sustainability of the supply chain will be promoted.
