Reverse logistics programming model of electronic wastes with fuzzy parameters

A reverse logistics network structure was established for six kinds of electronic wastes including color TV,refrigerator,air conditioner,washing machine,computer and mobile phone,and the reverse logistics programming model of electronic wastes with fuzzy parameters was built.Tolerance approach was used to make fuzzy constraints clear,the fuzzy programming model was turned into a deterministic linear programming model,and the model was solved by using WinQSB software.Considering Guangxi transportation development situation and the disposal costs of electronic wastes in other regions,the locations of remanufacturing centers,testing centers and landfills in Guangxi were calculated respectively at different confidence levels,and the reverse logistics network of electronic wastes in Guangxi was determined.Analysis result indicates that when confidence levels are 0.80,0.90,0.95 respectively,the node functions of reverse logistics network for electronic wastes in Guangxi remain unchanged,and the processing quantities of remanufacturing centers are 24 532.2,25 089.7,25 368.5 t respectively.5 tabs,4 figs,15 refs.
