Zhongsheng Hua · Zhongguo guanli kexue · 2010
To overcome deficiencies using non-uniform inputs/outputs data to evaluate the efficiency of existing interval DEA methods,this paper presents an interval DEA method based on overall efficiency.The method optimizes the system efficiency,determines the accurate data of interval inputs/outputs and solves all DMUs' efficiency.A numerical example is employed to illustrate the effectiveness and superiority of the proposed method.
