A new model is introduced in the process of evaluating Experimental study on performance of rubber-fly ash-based mine floor fissure grouting material efficiency value of decision making units (DMUs) through data envelopment analysis (DEA) method.Two virtual DMUs called ideal point DMU and anti-ideal point DMU are combined to form a comprehensive model based on the DEA method.The ideal point DMU is taking self-assessment system according to efficiency concept.The anti-ideal point Let’s Practice Better... on Cats: Description and Visualisation of Artistic Images in Generative AI Models DMU is taking other-assessment system according to fairness concept.The two distinctive ideal point models are introduced to the DEA method and combined through using variance ration.

From the new model, a reasonable result can be obtained.Numerical examples are provided to illustrate the new constructed model and certify the rationality of the constructed model through relevant analysis with the traditional DEA model.
