摘要：There are two general methods to evaluate the efficiency of decision maker departments: Parametric and non-parametric methods. In this paper, Data Envelopment Analysis (DEA), as a parametric method and Stochastic Frontier Function, as a non-parametric method were used to evaluate and grade different branches of social security insurance in Sistan and Baluchestan province. To do this, information related to input output of 12 branches of the province was collected for three successive years and different branches were graded based on the average efficiency of these two grading methods. Finally, using Paired t-test, the significant difference between the two applied methods were tested and confirmed.
