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...
Then an integrated mathematical model of p-hub median problem and service facility configuration was constmcted. A numeric example with the scale of 9 cities, 4 types of aircraft and 72 OD pairs in domestic airline industry in 2016 is used to verify the feasibility. The results indicated that...
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...
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...
