The Latest Arrival Hub Location Problem
传统枢纽选址问题只考虑飞行时间，忽略了货物在枢纽装卸分拣的暂留时间。本文针对货运系统，建立同时考虑飞行时间和暂留时间的模型，以最小化最后到达货物的到达时间，并分析延误对系统性能的影响。
The traditionally studied hub location problems in the literature pay attention to flight times but not to transient times spent at hubs for unloading, loading, and sorting operations. The transient times may constitute a significant portion of the total delivery time for cargo delivery systems. We focus on the minimization of the arrival time of the last arrived item in cargo delivery systems and develop a model that correctly computes the arrival times by taking into account both the flight times and the transient times. Nonlinear and linear integer formulations are given and computational results are provided. The effects of delays on the system performance are analyzed.
