摘要
通过将粗糙变量引入决策单元投入产出要素,本文将DEA模型与实域广义粗糙集结合起来,建立了粗糙DEA模型,并给出了模型的求解方法。新模型拓展了对不确定DEA理论的研究。
By introducing rough variable into the evaluation of relative efficiency of DMU, this paper combined the DEA model with generalized rough set based on the real domain. Then this paper gave the arithmetic of the rough DEA model. This new model developed the research of uncertain DEA model.
