Notes on classifying inputs and outputs in data envelopment analysis: A comment

Mehdi Toloo

European Journal of Operational Research, 2014, vol. 235, issue 3, 810-812

Abstract: Cook and Zhu (2007) introduced an innovative method to deal with flexible measures. Toloo (2009) found a computational problem in their approach and tackled this issue. Amirteimoori and Emrouznejad (2012) claimed that both Cook and Zhu (2007) and Toloo (2009) models overestimate the efficiency. In this response, we prove that their claim is incorrect and there is no overestimate in these approaches.
