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...
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 of trans-shipped containe 然而,它的效率依靠强烈容器终端的地点。 在本文,一套估计的潜在的...
