摘　　要：考虑高速铁路车站咽喉区和到发线的相互制约关系,以及车站接发各种类型列车的作业过程与列车进路的关系,结合道岔分组的方法,建立咽喉区和到发线一体化运用的列车进路分配方案优化模型。在此基础上,考虑列车晚点的情况,以车站作业过程占用车站设备的不均衡性最小和列车进站延误时间最短为目标,建立后续列车进路分配方案的动态调整模型。2个模型均采用运筹学软件LINGO中内置的分支定界算法求解。通过算例验证模型的合理性和求解方法的可行性。结果表明:当列车按照图定时刻正点运行时,采用优化模型得到的列车进路分配方案可以保证列车按照图定时刻进出站;当某列车晚点时,该列车的进路可能与后续列车的进路有交叉干扰,此时则应采用动态调整模型对后续列车的进路分配方案进行调整,在后续列车允许有延误时间的约束下,生成新的后续列车进路分配方案,有效保证列车进路的畅通,并使车站设备运用的均衡性更优。Considering the restriction between throat area and arrival-departure track in high speed railway station,the connection between the operation process of various types of trains and train routes in the train reception and departure process,in combination with the method of turnout grouping,the optimization model of train route allocation scheme was established based on the integrated application of throat area and arrival-departure track.On this basis,taking the train delay into account,with the minimum disequilibrium use of station equipment and the minimum train delay time as optimization objectives,the dynamic adjustment model of train route allocation scheme for follow-up trains was established.The models were solved by the branch and bound algorithm built in the operational research software LINGO.The rationality of the model and the feasibility of algorithm were verified by an example.Results show that when trains run on schedule according to train diagram,the train route allocation scheme can be obtained by using the optimization model,which ensures trains passing in and out station according to train diagram.When a train is late,there may be cross-interference between the route of this train and the routes of follow-up trains.At this point,the dynamic adjustment model should be adopted to adjust the train route allocation scheme for follow-up trains.With the constraint that the delay of follow-up trains is allowed,a new train route allocation scheme for follow-up trains can be obtained,which effectively ensures the train route unimpeded and the balanced utilization of station equipment more optimal.
