DEA method often leads to multiple units being effective and makes the evaluation results meaningless when evaluating the efficiency of complex systems. It is difficult to find the projection of the original index when these indexes are synthesized into several main indexes. In order to solve the above problems, a DEA model for efficiency evaluation of output-oriented complex systems is presented in this paper. The meanings of DEA validity, model properties and solving methods of the model are discussed. Finally, this method is used to analyze the comprehensive operation efficiency of 14 grade 3A hospitals in Inner Mongolia Autonomous Region.
