چکیده مقاله :
In this paper, we develop the revenue and cost efficiency models based on the FDH model. In the following, we will develop the proposed models for the two-stage network structure and obtain the desired scores of inputs and outputs by considering the input and output prices. An algorithm for measuring the revenue and cost efficiency is presented based on the ratio of inputs and outputs.
در دنیای حقیقی ممکن است تصمیم گیرنده بخواهد کارایی هزینه و درآمد را برای واحدهای تصمیم گیرنده موجود در مقابل برای واحدهای تصمیم گیرنده مجازی انجام دهد در اینصورت دیگر نمی توان از مدلهای سنتی تحلیل پوششی داده ها استفاده نمود و باید از مدلهای FDH به منظور ارزیابی کارایی واحدهای تصمیم گیرنده استفاده نماییم. در این مقاله مدلهای ارزیابی کارایی درآمد و هزینه را بر اساس مدلهای FDH و مقایسات زوجی توسعه می دهیم. در ادامه مدلهای ارائه شده را برای شبکه دو مرحله ای توسعه میدهیم و مقادیر مطلوب ورودیها و خروجیها را با توجه به قیمت آنها بدست می آوریم. یک الگوریتم برای اندازه گیری کارایی هزینه و درآمد بر اساس نسبت ورودیها و خروجیها ارائه شده است. سرانجام الگوریتم ارائه شده را برای ارزیابی کارایی 13 فرودگاه با ساختار شبکه دو مرحله ای در ایران بدون در نظر گرفتن قید تحدب بکار می بریم. در انتها نتایج حاصل از تحقیق را ارائه میدهیم.
