A technical note on 'erratum to "Finding the most efficient DMUs in DEA: An improved integrated model" [Comput. Indus. Eng. 52 (2007) 71-77]'

Abstract

You et al. (2013) indicated two errors in Amin and Toloo (2007). The first error was the infeasibility of Amin and Toloo’s (2007) model and the second drawback was the lack of a suitable value for the non-Archimedean epsilon in the proposed approach of Amin and Toloo (2007). This paper deals with the raised issues and proves that the model of Amin and Toloo (2007) is always feasible. In addition, we also formulate a new model for finding a suitable value for the epsilon.
