以物流运输活动中不同货物运输链的选择为研究对象,建立了多层Logit模型进行具体地研究。以效用理论为基础,分析了不同运输链中运输方式的各种影响因素,按照运输方式的特点,将运输链分为多方式和单一方式两大类,并在此分类基础上建立了二层的选择树模型。利用调查数据对模型效用函数的参数进行了标定,并对参数的标定结果进行了验证。最后,通过具体实例证实了多层Logit模型在货物运输链选择研究中的实用性和有效性。
以物流運輸活動中不同貨物運輸鏈的選擇為研究對象,建立瞭多層Logit模型進行具體地研究。以效用理論為基礎,分析瞭不同運輸鏈中運輸方式的各種影響因素,按照運輸方式的特點,將運輸鏈分為多方式和單一方式兩大類,併在此分類基礎上建立瞭二層的選擇樹模型。利用調查數據對模型效用函數的參數進行瞭標定,併對參數的標定結果進行瞭驗證。最後,通過具體實例證實瞭多層Logit模型在貨物運輸鏈選擇研究中的實用性和有效性。

In order to select different freight transportation chain as the object of research in the logis-tics and transport activities ,a detailed study of nested logit model was established .Based on utility theory ,various influencing factors of transport mode in transport chain were analyzed .According to the characteristic of transport modes ,transport chains were divided into two categories ,namely single mode and multiple modes ,and based on this classification the selected tree model with two layers was built .Parameters of utility function using survey data were calibrated ,and the calibration results of the parameters were proved .Finally ,through the specific example ,the feasibility and efficiency of nested logit model in the application of transport chain selection were verified .
