基于IDEA模型的港口物流服务商优选方法

Port logistics service supplier selection method based on imprecise data envelopment analysis model

为科学地对港口物流服务商进行评估及选择,基于数据包络分析(DEA)模型,结合定性的不确定因素,提出非精确数据包络分析(IDEA)模型的港口物流服务商优选方法.该方法无需更多精确信息,并兼有一般DEA的特点,较好地解决了DEA无法处理定性因素的问题.算例分析结果表明了该方法的有效性和实用性.

To evaluate and select port logistics service suppliers scientifically,a method of IDEA model was proposed based on data envelopment analysis（DEA） model,considering the cardinal and imprecise factor in port vendor selection.The proposal method is more robust without demanding too much precise information and keeps the characteristics of the conventional DEA model so that it can solve such a problem well that it deals with the qualitative factors in DEA model but can＇t be settled therein.Numerical example shows the effectiveness and utilities of such method.
