چکیده مقاله :

ارزیابی عملکرد در تحلیل پوششی داده‌ها با استفاده از محاسبه کارایی تکنیکی حاصل می‌شود. اما آنچه که در این نوع محاسبه مد نظر قرار نمی‌گیرد قیمت ورودی‌های مدل است. در محاسبه کارایی تکنیکی مقدار خروجی به ورودی ماکزیمم می‌شود و با استفاده از مدل می‌توان واحد-های تصمیم گیری کارا را مشخص کرد در حالی که ممکن است واحد تصمیم گیری‌ای که در مرز کارایی است و مرجعی برای سایر واحد‌های تصمیم گیری است با صرف هزینه بالا کارا شده باشد و بتوان واحد تصمیم‌گیری‌ای یافت که با هزینه تولید پایینتری در مرز کارایی قرار گرفته باشد. کارایی هزینه به یافتن نقاطی می‌پردازد که با صرف کمترین هزینه بر روی مرز کارایی باشند. با توجه به اهمیت کارایی هزینه و عدم توجه به این مفهوم در ساختارهای شبکه‌ای و چند مرحله‌ای، این پژوهش به بررسی کارایی هزینه در فرآیند دو مرحله‌ای سری محض می‌پردازد. در تحقیق حاضر با بکارگیری مفهوم تئوری بازی‌ها و تحلیل پوششی داده‌ها در حالت متمرکز و غیر متمرکز به ارزیابی عملکرد فرآیندهای دو مرحله‌ای محض می‌پردازیم. به منظور بررسی اعتبار و کارایی مدل‌ها و نیز کاربردی بودن آنها یک مطالعه موردی در صنعت برق ایران مورد استفاده قرار گرفته است و به برخی از نتایج مدیریتی پرداخته می‌شود.

چکیده انگلیسی:

Performance evaluation in data envelopment analysis is obtained by using technical efficiency calculation. But what is not taken into account in this type of calculation is the price of model inputs. In calculating technical efficiency, the amount of output to the input is maximized, and the model can be used to identify efficient decision-making units, while it is possible to determine the decision-making unit that is at the efficiency limit and a reference for other units. Decision-making systems are efficient at a high cost, and it is possible to find decision-making units that are on the verge of efficiency at a lower production cost. Cost Efficiency seeks to find points that are on the edge of efficiency at the lowest cost. Given the importance of cost efficiency and the lack of attention to this concept in network and multi-stage structures, this study investigates cost efficiency in a purely two-stage process. In the present study, using the concept of game theory and data envelopment analysis in a centralized and decentralized state, we evaluate the performance of purely two-stage processes. In order to investigate the validity and efficiency of the models and their applicability, a case study has been used in the Iranian electricity industry and some management results are discussed.
