Research ArticleOpen accessPhrase in the titleAn Enhanced Russell Measure of Super-Efficiency for Ranking Efficient Units in Data Envelopment AnalysisAli Ashrafi, Azmi Bin Jaafar, Lai Soon Lee, Mohd Rizam Abu BakarProblem statement: Conventional Data Envelopment Analysis (DEA) helps decision makers to discriminate between efficient and inefficient Decision Making Units (DMUs). However, DEA does not provide more information about the efficient DMUs. Super-efficiency DEA model can be used in ranking the performance of efficient DMUs. Because of the possible infeasibility of radial super-efficiency DEA model, the ranking has been limited to … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 8,798 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleEfficiency Decomposition with Enhancing Russell Measure in Data Envelopment AnalysisTien-Hui Chen, Chiao-Pin Bao, Chi-Ming Huang, I-Chiang WangProblem statement: Most studies about the application of Data Envelopment Analysis (DEA) follow the concept of radial and non-radial efficiency measures. Because of some difficulties with the measure of weights, Russell measure utilizes the mean of all input/output efficiency measurements as the efficiency score of a specific business unit. However, this may render bias. Approach: This study provided a reasonable … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,051 accessesView PDF Cite
