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.
In order to scientifically evaluate and select the port logistics service providers, based on the data envelopment analysis (DEA) model, combined with the qualitative uncertainty, a port logistics service provider optimization method based on the inexact data envelopment analysis (IDEA) model is proposed. The method does not need more accurate information and has the characteristics of general DEA, so it solves the problem that DEA can not deal with the qualitative factors well.The example analysis shows the effectiveness and practicability of the method.
