(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...

We consider problems related to the generalization of the classical Fourier basis to a basis of rational functions with prescribed poles outside the unit disk. We give some generalizations about the convergence and estimation of the Fourier coefficients with respect to this generalized basis. We also consider a rational generalization of the classical Toeplitz matrices and consider the asymptot...

This paper explores the use of the optimisation procedures in SAS/OR software with application to the measurement of e#ciency and productivity of decision-making units (DMUs) using data envelopment analysis (DEA) techniques. DEA was originally introduced by Charnes et al. [J. Oper. Res. 2 (1978) 429] is a linear programming method for assessing the e#ciency and productivity of DMUs. Over the la...

Using panel data from China’s tobacco manufacturing industry 2014 to 2018, the DEA-Malmquist method is used measure green total factor productivity of on basis comprehensive consideration environmental pollution and energy consumption. The study found that Malmquist index basically showed a fluctuating upward trend; technical level 2014-2017 needs be improved, 2017-2018 has begun improve.

Agriculture is one of the main economic sectors in Türkiye. Therefore, a performance evaluation essential for an improvement agricultural sector. In this study, productivity Turkish sector was analyzed years between 2006-2015. A non-parametric technique, Data Envelopment Analysis (DEA) based Malmquist index method, applied to calculate Total Factor Productivity (TFP) indices agriculture 26 NUTS...
