چکیده
In the recent decade, data envelopment analysis (DEA) has been extended to evaluate the performance of two-stage processes. Two-stage process known as two-stage DEA is divided into two stages. The outputs produced from the inputs of the first stage are considered as inputs to produce the outputs of the second stage. These data are calledintermediate data. In the recent works on two-stage DEA, the efficiency of the total process is defined by acombination of the efficiencies of the two stages. However, the presented methods may not measure the relative efficiencies of two-stage processes. Therefore, present paper proposes a new two-stage DEA model which can obtain the relative efficiencies of two-stage processes. The method also preserves relation between the totalefficiency and the efficiencies of the stages. Some theorems related to the proposed approach are provided. Moreover, the proposed two-stage DEA model is compared to other approaches by using a case study in theliterature. Furthermore, the utilization of the proposed approach is demonstrated to evaluate 23 bank branches in Iranکلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
