In the world, China is one of greatest nation that products and expends lots of electrical appliances. Since the year of 2003, China's household appliances have entered the peak of obsolescence, which discards approximately more than 30 million every year. As China basically hasn't constructed regular reverse logistics system of discarded and used household appliances at present, the majority of them cannot be effectively recycled. The using period of household appliances will be shortened gradually and replace speed will be quickened with the development of science and technology, which aggravate the production speed of waste household appliances further. The waste household appliances contain much substance that harms human environment and a lot of resources that can be reused. If they are not disposed properly, our living environment will be polluted and many resources that can be reused will be wasted. This paper established a reverse logistics model of discarded and used household appliances. On the basis of the above research, built models based on the analysis, through example of mixed integer linear planning models based on the new reverse logistics network optimization model role.
