[ 1 ] - Improving envelopment in data envelopment analysis by means of unobserved DMUs: an application of banking industry
In data envelopment analysis, the relative efficiency of a decision making unit (DMU) is defined as the ratio of the sum of its weighted outputs to the sum of its weighted inputs allowing the DMUs to freely allocate weights to their inputs/outputs. However, this measure may not reflect a the true efficiency of a DMU because some of its inputs/outputs may not contribute reasonably in computing t...
[ 2 ] - اندازه‌گیری کارایی شرکتهای بیمۀ منتخب با استفاده از مدلهای دومرحله‌ای همراه با تحلیل پنجره‌ای در تحلیل پوششی داده‌ها
در سالهای اخیر، ارزیابی شرکتهای بیمه مورد توجه بسیاری از محققان قرار گرفته است. ارزیابی شرکتهای بیمه نقش مهمی در بهبود عملکرد آنها دارد. یکی از پرکاربردترین روشهای ارزیابی عملکرد، به‌ویژه در سالهای اخیر، تحلیل پوششی داده‌هاست. در این مقاله، تغییرات نرخ کارایی 5 شرکت بیمه‌ای منتخب با توجه به عملکرد آنها در سالهای 1389 تا 1392، با استفاده از تحلیل پوششی داده‌ها همراه با تحلیل پنجره‌ای مورد بر...
[ 3 ] - An Insight into the Model Structures Applied in DEA-Based Bank Branch Efficiency Measurements
In this paper, we focus on the Data Envelopment Analysis (DEA)-based model structures have been used in assessing bank branch efficiency. Probing the methodologies of 75 published studies at the branch level since 1985 to early 2015, we found that these models can be divided into four categories: standard basic DEA models, single level and multi-level models, enriched (hybrid) models and specia...
[ 4 ] - Combined Role of Manpower Ethics and Physical Space Facilities of Bank Branches in Productivity Analysis
Productivity growth and efficiency improvements are the major sources of economic development. Pure efficiency, scale efficiency, and technology are basic factors, and rules and regulations and balance are recently known factors affecting the productivity growth. This paper focuses on the effect of manpower ethics and physical space facilities of bank branches as two factors affecting the Malmq...
[ 5 ] - An ethics-based decomposition of Malmquist productivity index using data envelopment analysis
Productivity growth and efficiency improvements are the major sources of economic development. Pure efficiency, scale efficiency, and technology are basic factors, and rules and regulations and balance are recently known factors affecting the Malmquist productivity index. The index is the most common productivity growth index that uses data envelopment analysis models over multiple time periods...
