改善公铁联运“门到门”运输时效是促进公铁联运发展的重要内容。既有文献主要关注公铁联运“门到门”运输中局部环节的时间可靠性分析，针对公铁联运“门到门”全流程时间可靠性的研究不足。为此，依据公铁联运“门到门”全流程的作业环节分析，以可靠度、合并样本标准差和预留时间为可靠性度量指标，提出基于离散事件流程链仿真的公铁联运“门到门”运输时间可靠性评估方法，并采用灵敏度分析探究公铁联运“门到门”运输中公路运距占比、列车编组数量、轨道门吊数量和牵引机车数量对“门到门”运输时间可靠性的影响。结果表明：随着公路运距占比的提高、编组数量的减少、轨道门吊数量和牵引机车数量的增加，“门到门”运输时间显著缩短，而“门到门”运输时间可靠性随公路运距占比的增加而降低。当公路运距占比小于0.4时，“门到门”运输时间可靠性随编组数量的增加而降低；当公路运距占比大于0.4时，编组数量变化对“门到门”运输时间可靠性影响不显著。轨道门吊数量增加能够提高“门到门”运输时间可靠性，但增加到一定水平后，可靠性的提升效果逐渐减弱。研究成果对铁路运输企业提升公铁联运服务水平，促进多式联运发展具有重要意义。
