Conventional techniques, used to evaluate performance, are single-level and cannot provide enough managerial information to identify the inefficient factors of the inefficient units and attain the benefits and disadvantages of competitive strategies. However, the multilevel data envelopment analysis can overcome this problem. One of the most important problems with classical models is to ignore the internal relations of each unit in performance evaluation. In this paper, a multilevel mathematical model is designed to evaluate the performance of bank branches using the Stokklberg game concept and multivariate programming, which solves the problems of previous models and is able to provide a more realistic assessment of the efficiency of bank branches %> http://jamlu.liau.ac.ir/article-1-1514-en.pdf %P 41-66 %& 41 %! %9 Research %L A-11-1328-1 %+ Department of Industrial Management, Faculty of Economic and Management, Shiraz Branch, Islamic Azad University, Shiraz %G eng %@ 2251-7286 %[ 2017
