The invention discloses a railway empty wagon allocation method based on timeliness and emergency relief material priority. A satisfaction optimization theory is considered, temporal satisfaction functions are used, vehicle type substitution and the actual situation of short supply of railway empty vehicles on the road network at present are combined. The priority of the emergency relief materialsafter the sudden natural disasters occur is considered to establish a railway empty wagon allocation comprehensive model, and the LINGO is used for solving, so that the timeliness of an existing railway empty car allocation method and the accuracy of emergency relief material transportation are improved through the obtained railway empty wagon allocation scheme. 本发明公开了一种基于时效性和应急救灾物资优先权的铁路空车调配方法基于时效性这一目标，考虑满意优化理论，使用时间满意度函数，结合车种代用以及目前路网上铁路空车总体上供不应求的实际情况，考虑突发性自然灾害发生后应急救灾物资的优先权以此建立一个铁路空车调配综合模型，并使用LINGO求解，得到的铁路空车调配方案提高了现有铁路空车调配方法的时效性和针对应急救灾物资运输的准确性。
