| 摘 要： | 对非精确数据包络分析（IDEA）的研究进行了简要的归纳与总结．首先，简要回顾了有关I—DEA的研究进展；其次，给出了非精确数据的定义与分类，将非精确型数据分为：边界数据、弱序数据、强序数据和比值有界数据；同时给出了几个基本假设和相关模型；接着，构建了一个适用于非精确型数据的IDEA模型，并且给出了尺度变换法和变量交替法以实现将非线性规划问题转换成线性规划问题；最后，为了提高求解效率，对Zhu提出的简化变量交替法进行了改进，指出这将减少实际应用中的计算复杂度．

| Abstract: | This paper gave a brief review of imprecise data envelope analysis(IDEA).Firstly,the study of IDEA was briefly reviewed;secondly,the imprecise data,including the bounded data,the weak ordinal data,the strong ordinal data,and the ratio bounded data were defined and classified;some basic assumptions and models were also presented;then,an IDEA model was constructed which is suitable for applying the imprecise data;and then,the scale-transformation and variable-alternation approach were presented in order to co... |
