A non-parametric Data Envelopment Analysis approach for improving energy efficiency of grape production

Khoshroo, Alireza; Mulwa, Richard; Emrouznejad, Ali; … - In: Energy 63 (2013) C, pp. 189-194

Grape is one of the world's largest fruit crops with approximately 67.5 million tonnes produced each year and energy is an important element in modern grape productions as it heavily depends on fossil and other energy resources. Efficient use of these energies is a necessary step toward reducing...

An aggregate measure of financial ratios using a multiplicative DEA model

Emrouznejad, Ali; Cabanda, Emilyn - In: International Journal of Financial Services Management 4 (2010) 2, pp. 114-126

This paper examines the problems in the definition of the General Non-Parametric Corporate Performance (GNCP) and introduces a multiplicative linear programming as an alternative model for corporate performance. We verified and tested a statistically significant difference between the two models...

Selecting between different productivity measurement approaches: An application using EU KLEMS data

Giraleas, Dimitris; Emrouznejad, Ali; Thanassoulis, Emmanuel - Volkswirtschaftliche Fakultät, … - 2012

Over the years, a number of different approaches were developed to measure productivity change, both in the micro and the macro setting. Since each approach comes with its own set of assumptions, it is not uncommon in practice that they produce different, and sometimes quite divergent,...
