aHowever, its efficiency is strongly dependent on the location of the container terminals. In this paper, a set of estimated potential locations is used as input for an iterative procedure based on the p-hub median problem that takes the variation in trans-shipment costs according to the number...
以下理解是否正确: 假设项目总数为P,员工总数为N, 问题是求N/P的中位数。 条件1)N/(25%*P)>=4 ,简化为N/P>=1 条件2)N/(0.35%*P)<=2 简化为N/P<=0.7 但条件1)和2)合在一起不能得到N/P的范围,得不出结果啊,选了E。错误在哪里呢?
p-中心问题与p-中位问题是两类基本的选址问题,在选址问题的研究中占有十分重要的地位。 p-center Problem and p-median Problem:A Survey;
