An extended quality-driven efficiency-adjusted data envelopment analysis (QE-DEA) method is developed to measure the performance of service units. Performance is measured based on efficiency and users’ satisfaction. The extended QE-DEA method identifies as benchmarks only units that are...

Network data envelopment analysis (NDEA) is an extension of standard data envelopmentanalysis (DEA) that models the efficiency assessment of DMUs by considering their internalstructure. While in standard DEA the DMU is regarded as a single process, in NDEA the DMUis viewed as a network of...

T his paper consists in measuring the performance of some banks in Tunisia during the year 2004. This purpose we used the Data Envelopment Analysis (DEA) method under a linear programming using GAMS software. Within this analysis, we presented two banking approaches: intermediate and productive;...

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...

When production functions are estimated as frontier functions, the deviations from the frontier can be interpreted as individual inefficiency estimates. Unfortunately, it has recently been shown that efficiency differences across individuals are very often statistically insignificant. In this...

The formulas of cost and allocative efficiencies of decision making units (DMUs) with positive data cannot be used for DMUs with negative data. On the other hand, these formulas are needed to analyze the productivity and performance of DMUs with negative data. To this end, this study introduces...

This paper uses data envelopment analys is to investigate the extent to which universities in the United States have undergone productivity and efficiency changes, partly due to managerial performance, during the 2005-09 academic years. Using panel data for 133 research and doctoral...
