چکیده

تعیین کارایی هر سیستم جهت برنامه ریزی از ضروریات آن سیستم می باشد. اغلب برای تعیین کارایی سیستم از مدل های تحلیل پوششی داده ها استفاده می شود. در این مقاله ساده ترین و کاربردی ترین سیستم  های دو مرحله ای تحت عنوان سیستم دو مرحله ای پایه معرفی شدند. سپس مدل های TSDEA ارائه شده در خصوص آنها که مبتنی بر اندازه های تابع فاصله هستند مطالعه و بررسی قرار داده شدند. در ادامه مدل های TSDEA غیر شعاعی مبتنی بر ایده راسل توسعه داده شدند. در نهایت یک مثال عددی حل شد.

چکیده [English]

Determining the efficiency of each system for scheduling is one of the requirements of that system. Data envelopment analysis models are often used to determine the performance of systems. In this paper, the simplest and most practical two-stage systems are introduced as the basic two-stage system. Then the proposed TSDEA models based on the distance function measures are investigated. Subsequently, Russell's idea of non-radial TSDEA models was developed.
