Abstract
In data envelopment analyze (DEA) the scale efficiency in the input-oriented CCR model is less than
or equal to the scale efficiency in DEA based on the fractional analysis (DEA-R). Also, the scale
efficiency in case of multiple inputs and one output and vice versa the scale efficiencies are equal in
DEA and DEA-R. In this paper, first, DEA-R model with weight restrictions when there is relative data
is recommended. Second, the scale efficiencies in a constant return to scale are compared with each
other in DEA and DEA-R models. At the end, a numerical example is provided for the proposed models
with 27DMUs.
Farsi abstract
در تحليل پوششي داده ها مقياس كارايي در مدل CCR با ماهيت ورودي كوچكتر يا مساوي مقياس كارايي در تحليل پوششي داده ها مبتني بر تحليل كسري (DEA-R) مي باشد . همچنين مقياس كارايي در حالت چند ورودي و يك خروجي و بالعكس مقياس هاي كارايي در DEA و DEA-R برابر هستند. در اين مقاله اولا مدل DEA-R با محدوديت وزني در حالتي كه داده ها نسبتي باشد پيشنهاد مي شود. ثانيا مقياس هاي كارايي در حالت بازده به مقياس ثابت در DEA و DEA-R با يكديگر مقايسه مي شود. در خاتمه مثال عددي با 27 واحد تصميم گيرنده براي مدل هاي پيشنهادي ارايه مي شود .
