摘要: Abstract. In data envelopment analysis each decision making unit is analyzed in best situation and CCR models for the under weights are considered inputs outputs. So, if its less than one, it inefficient, otherwise efficient. Therefore, present article an attempt to achieve cross efficiency matrix by using SBM then rank units matrix. Overall, selecting optimal portfolio done order find efficient firms mean, column variance covariance of scale utilized. Finally, 22 with two one output has been calculated non-radial models.
