چکیده
Efficiency frontier analysis is an important approach of evaluating performance of different sectors in indsustry. This paper presents an adaptive neural network and fuzzy transform approach for the coal consumed by industrial sectors in 20 different US states including District of Columbia. The behavior of the coal consumption is assessed based on the data during 1960–2011. Despite of the strengths of these approaches, they have their own limitations. The proposed algorithms are able to find a stochastic frontier based on a set of observational input–output data and explicit that assumptions about the functional structure of the stochastic frontier are not needed. By applying these algorithms and calculating the efficiency scores, the ranking between decision-making units (DMUs) will be available. The superiority and advantages of adaptive neural network algorithm are shown by comparing its results against fuzzy transform algorithm.کلیدواژه ها

اطلاعات بیشتر در مورد COI
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.
