A Modified Integer DEA Model and Its Application in Social Science Research of Central and Western Universities
Sometimes,the conventional DEA model cannot give a precise projection for the integer-valued decision-making unit.Moreover,existing integer DEA models also have drawbacks of the inaccuracy of projection points and the complication of the model.Therefore,this paper points out and illustrates the drawbacks of the previous integer DEA models.Besides,we develop a modified model and then discuss the character and the relationship between the proposed model and previous integer DEA models.It is noted that the input-output maybe contain both integer-valued and real-valued in real evaluation.Therefore,this paper further introduces a modified mixed integer DEA model based on the above-proposed model.Additionally,the introduced model will be used to analyze and compare the social science research efficiency and optimization of 102 universities in central and western China.
