Optimal Design of Reverse Logistics Recycling Network for Express Packaging Considering Carbon Emissions

With the development of China’s express delivery industry, number packaging has proliferated, leading to many problems such as environmental pollution and resource waste. In this paper, process reverse logistics network design for recycling is given an example in M region, a four-level containing primary nodes, centers, processing terminals established. A candidate node selection model based on K-means algorithm constructed cluster by distance from 535 courier outlets select 15 nodes centers centers. NSGA-II identify with minimizing total cost carbon emission objective function, set Pareto solution sets 43 solutions obtained. According distribution set, are classified into I, II, III categories. The results indicate that corresponding Class I II can be selected when system gives priority cost, benefits, society-wide developed certain extent. addition, paper also randomly selects sample each three types sets, conducts coding interpretation site selection, vehicle treatment technology scheme.
