【摘要】 研究了生态旅游区废弃物逆向物流网络设计问题,包括中转站选址和车辆路径问题,并建立了最小化选址费用和运输费用的模型。选址路径问题为NP困难问题,本文采用了四叉树原理划分满足车辆容量限制的收集区,将问题化为小型的TSP问题。更多还原

【Abstract】 The paper studies the design of reverse logistics network for solid wastes in eco-tourist areas,including transfer station location and vehicle routing problems,establishes a model with minimized location expense and transport fees and introduces the quadr-tree principle to divide the collecting zone which caters to the needs of vehicle capacity limits in order to turn a NP-hard location/routing problem into a TSP problem.更多还原
