摘要
本文在DEA中的C2R模型的基础上,针对决策单元输入与输出为区间上的连续函数,建立了在一个时间区间[0,1]内评价决策单元间的相对有效性的连续模型以及与之等价的模型,同时给出了决策单元的效率定义和弱DEA有效、DEA有效的定义。为经济管理中相关问题的研究与解决提供了一种新的方法。
Based on C^2R model in DEA, the continuous C^2R model, which is employed to evaluate the relative efficiency among decision making units, is established in this paper when the inputs and outputs of decision making units are continuous functions that are defined at interval [0,1 ]. At the same time, we give the definition of efficiency for decision making units, the definition of weak DEA efficiency, the definition of DEA efficiency, and we also propose a new method to study and solve the relative topics in economics and manegement.
