In consideration of the actual production process consisting of several stages,and of the traditional DEA model being only applied on those decision-making units that have only one single stage,a multi-stage-oriented DEA model should be established to solve the problem.Based on the traditional DEA models,this paper achieves the destination by analyzing input and output data on every stage.The multi-stage-oriented DEA model can evaluate the relative efficiency of the decision-making units that have several stages in sense of the whole production process.
