摘要
为了确保物流配送中心选址的合理性,节约配送里程,降低配送的费用成本,将聚类-重心法和CFLP(Capacitated Fa⁃cility Location Problem)模型结合起来对城市的物流配送中心选址进行研究。首先,用最短距离聚类法进行配送区域划分;其次,通过CFLP模型结合聚类结果,以物流配送成本费用最小化原则选出二级物流配送中心;再次,分别对二级物流配送中心和城市中所有的区域物流配送中心使用重心法求出2个一级物流配送中心的坐标;最后,分别计算出2个一级配送中心的配送总距离和配送总费用,并进行对比分析。结果表明:选择通过对二级物流配送中心使用重心法求出的一级物流配送中心作为最终一级物流配送中心最为合理。该方法能应用到两级物流的配送中心选址过程中。
In order to ensure the rationality of the location of logistics distribution center,save the distribution mileage and reduce the cost of distribution,this paper combines the clustering-gravity method and CFLP(Capacitated Facility Location Problem)model to study the location of urban logistics distribution center.Firstly,the distribution area is di-vided by the shortest distance clustering method.Secondly,based on the CFLP model and clustering results,the second-ary logistics distribution centers are selected based on the principle of minimization of logistics distribution costs.Then,the coordinates of the two first-level logistics distribution centers are obtained by using the center of gravity method for the second-level logistics distribution centers and all the regional logistics distribution centers in the city.Finally,the to-tal distribution distance and total distribution cost of the two first-level distribution centers are calculated,and the com-parative analysis is carried out.The results show that it is the most reasonable to choose the first level logistics distribu-tion center which is obtained by using the center of gravity method for the second level logistics distribution center as the final first level logistics distribution center,and the method can be applied to the location selection process of the distri-bution center of the second level logistics.
