摘    要:从系统研究的角度出发,同时研究固体废弃物回收中转站的选址和废弃物运输路线的安排,建立了选址路径规划问题的模型———PLRP IF模型,并采用两阶段Tabu搜索启发式算法对该模型进行求解,得到合适的中转站位置和数目,并给出了较优的车辆调度.最后,通过算例验证了模型和求解算法的有效性.

关 键 词:城市固体废弃物  选址路径问题  PLRPIF模型  Tabu搜索算法

Abstract:How to save the cost of collection and transportation is one of the biggest problems in the solid waste management. In this paper, the periodic vehicle routing problem with intermediate facilities, i.e. waste transfer stations, was analyzed. There are two kinds of vehicles, collection vehicles and transportation vehicles, and some transfer stations in the system. The collection vehicles can renew their capacity at the transfer stations, where the transportation vehicles can get the waste container. The objective of this paper is to combine the location of the transfer station and the vehicles routing into a mathematical model, which is called PLRP-IF model, to minimize the system operation cost. And a two-phase Tabu search algorithm was developed to solve this model. Finally the computational result of the instances taken from the literature was presented.
Keywords:Municipal Solid Waste  Location-Routing Problem  PLRP-IF Model  Tabu search algorithm
