灰色数据包络分析的规模收益分析

Estimating returns-to-scale in grey data envelopment analysis

从可变规模收益模型(BCC)出发,探讨了灰色BCC模型的白化方法及其规模收益分析,得到了含区间灰数BCC模型规模收益的判定定理.算例分析表明了该方法的可行性与实用性,拓宽了灰色DEA模型的应用范围.

Grey data envelopment analysis(DEA) was studied by many scholars.However,there is no consideration of the returns to scale of the grey DEA models in the literature.Therefore,in this paper,we provide an approach for estimating the returns to scale in grey variable returns to scale DEA models.An illustrative example shows the practicability and usefulness of this approach.
