problem and traditional P-median location problem applied to European 150 data set are presented.Several solutions derived from these models are presented in greater detail and demonst rate the degree to which the loss of R facilities affects network system efficiencies with different location strategy...
通过求解72个标准测试例子以检验算法的性能,发现该算法在较短时间内得到了高质量解,优于现有算法.%The obnoxious p-median problem is known to be NP-hard.A hybrid evolutionary algorithm is proposed to solve the obnoxious p-median problem.Firstly,an initial population is generated by a greedy randomized...

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;
