摘　　要：针对既有的铁路空车调配问题研究缺乏可靠性,且模型多数使用货主满意度的情况,本文提出了一种考虑时效性的空车调配多目标优化方法。通过分析铁路空车调配过程,基于成本与时效性,定义了空车调配过程的可靠性,建立了运输企业成本最小和运输效益最大的多目标优化模型,并计算得到整个过程的可靠性值。最后,应用LINGO编程软件进行了实例计算,与既有研究方法比较的结果表明,该方法的实用性良好。Given that the existing study on railway empty car allocation lacks reliability and most models use owner satisfaction,a new multi-objective optimization model involved in timeliness was presented in this paper. By analyzing railway empty wagon and based on the cost and timeliness,the reliability of this process was defined,and a multiobjective optimization model with the least cost and the largest benef distribution it was established. Furthermore,the reliability value of the whole process was calculated. Finally, a numerical example was used to demonstrate the effectiveness of this method with LINGO software. Compared with the existing research methods,results show that the method proposed in this paper is practical.
