摘　　要：当被评价的决策单元的其输入向量增加后,其效率指数为原来的 r 倍时,极大化其输出向量,称这一问题是面向输出的 r-逆 DEA 问题,它是通常的逆 DEA 问题的推广.通过构建两个特殊的线性规划模型,得到了 r-逆 DEA 问题的一类特殊形式解的求法,并用数值实例加以说明.The DMU with inputs increased, and its efficiency level became r times to primal level, how much more outputs could the unit produce, such problem was called r-inverse DEA problem in this paper. It is the extension of general inverse DEA problem. By constructing two special linear programming models, an approach to get a kind of solution for r-inverse DEA problem had been ob- tained, with the illustration by a numerical example.
