This paper considers the relationship between Tolerance sensitivity analysis in optimization and metric sensitivity analysis in Data Envelopment Analysis (DEA). Herein, we extend the results on the generalized Tolerance framework proposed by Wendell and Chen and show how this framework includes DEA metric sensitivity as a special case. Further, we note how recent results in Tolerance sensitivit...

با توجه به اهمیت کارایی در پیشبرد جوامع و جایگاهی که سازمان‏های امروزی به خود اختصاص داده‏، استفاده از ارزیابی عملکرد به ضرورتی گریز ناپذیر تبدیل شده است. از این رو در این پژوهش سعی بر آن داریم تا با استفاده از تلفیق دو رویکرد DEA-BSC و ANN-DEA به بررسی کارایی سازمان‏ها بپردازیم. در این راستا، ابتدا به تعیین شاخص­های عملکرد به کمک تکنیک کارت امتیازی متوازن در چهار بعد مشتری، فرآیندهای داخلی، رش...

Operator allocation is one of the most important decisions that can influence productivity in the laborintensive manufacturing system. In this paper 10 operator allocation alternatives are identified with the assistance of computer simulation. To determine the best operator allocation, AHP/DEA and DEA Cross Efficiency are used. The results of both techniques are compared. Based on the results, ...

We survey the methodological advances in DEA over the last 25 years and discuss the necessary conditions for a sound empirical application. We hope this survey will contribute to the further dissemination of DEA, the knowledge of its relative strengths and weaknesses, and the tools currently available for exploiting its full potential. Our main points are illustrated by the case of the DEA stud...

In this paper, we re-examine Data Envelopment Analysis models from perspectives of preference order, production set and performance measure. we investigate the relationship between Data Envelopment Analysis (DEA) and Multiple Criteria Decision Making Theory. There are three key building blocks in a DEA model: preference order, production possibility set and performance measure. It is shown in t...

عملکرد، ابزاری می باشند که پس از اجرا می توانند اطلاعات گوناگونی را در اختیار تصمیم گیرندگان قرار دهند. بنابراین استفاده از اینگونه مدلها به منظور پاسخگویی به سؤالات و مسائلی که در ذهن تصمیم گیرندگان شکل گرفته است، اجتناب ناپذیر می باشد. در این صورت در این مقاله سعی شده تا مدل ریاضی تحلیل پوششی داده های مناسب، رتبه بندی کارایی گروههای آموزشی، نقاط ضعف و قوت هر یک از گروهها و وضعیت استفاده بهینه...

Data envelopment analysis (DEA) is a non-parametric approach for measuring the relative efficiencies of peer decision making units (DMUs). Many studies have examined DEA efficiencies of two-stage systems, where all the outputs from the first stage are the only inputs to the second stage. Although single-stage DEA models with undesirable input-outputs have been extensively studied, there still l...

Anaerobic lagoons are commonly used for the treatment of swine wastewater. Although these lagoons were once thought to be relatively simple, their physical, chemical, and biological processes are very complex. This study of anaerobic lagoons had two objectives: (i) to quantify denitrification enzyme activity (DEA) and (ii) to evaluate the influence of lagoon characteristics on the DEA. The DEA ...

Data Envelopment Analysis (DEA) is a non-parametric method for evaluating the efficiency of Decision Making Units (DMUs) with multiple inputs and outputs. In the traditional DEA models, the DMU is allowed to use its most favorable multiplier weights to maximize its efficiency. There is usually more than one efficient DMU which cannot be further discriminated. Evaluating DMUs with different mult...

(2011). " Formative evaluation of electricity distribution utilities using Data Envelopment Analysis ". Abstract — The use of Data Envelopment Analysis (DEA) in the electricity distribution sector has been prolific in the number of papers published in research journals. However, while numerous studies have been documented, they have mostly been summative. Their aim has been predominantly descri...
