摘　　要：应用随机用户平衡理论定量研究城市轨道交通网络运营鲁棒性.假设任一车站或区间及其波及范围退出运营,利用基于固定需求下和弹性需求下随机用户平衡条件的配流模型,从分析客流量、时间以及客流出行总时间波动的角度,提出9个城市轨道交通网络运营鲁棒性指标,并依据指标值最小原则确定网络的关键车站和区间.算例表明:该研究工作是可行有效的;与区间退出运营相比,车站退出运营的鲁棒性指标值区间跨度较大.Urban rail transit network operation robustness was quantitatively studied by stochastic user equilibrium theory. Under the assumption of child network without a station or route and its affect range, passenger flow assignment models separately based on fixed and elastic demand stochastic user equilibrium were used. Nine urban rail transit network operation robustness indices were proposed considering relative fluctuation of passenger flow, time and all the time of passenger flow. The key station and the key route of network, which lost from the network affecting operaion indices mostly, were identified obeying the least indice principle. A numerical example indicates that the research of this paper is feasible and effective, and robustness indice value range of losting station is much greater than that of losting route.
