In recent years there has been an exponential growth in the number of publications related
to theory and applications of Data Envelopment Analysis (DEA). Charnes, Cooper, and …

This paper deals with inverse DEA from both theoretical and applied viewpoints. First, some
methodological approaches and theoretical results are outlined; and then an application of …

This article reviews the estimation of Returns To Scale (RTS) in Data Envelopment Analysis
(DEA), presented by Golany and Yu and proposes a new method to do this estimation. we …

This paper first reviews Kerstens and Vanden Eeckaut's (K&VE) method [Kerstens, K.,
Vanden Eeckaut, P., 1999. Estimating returns-to-scale using non-parametric deterministic …

This paper provides a polynomial-time algorithm to estimate returns to scale in FDH models,
having many strong computational advantages. The equivalence of this method and the only …

Unemployment is a socio-economic fact that countries could not eradicate entirely, but effort
to minimize. The efficiencies of employment policies which are applied for this purpose can …

This paper deals with the estimation of returns to scale (RTS) in free disposal hull (FDH)
models and provides some stability intervals for preserving the RTS classification. It has …

In this paper, by improving the Golany and Yu's method [Estimating returns to scale in DEA,
European Journal of Operational Research 103 (1)(1997) 28–37], a new algorithm to …

This paper provides a recursive enumeration algorithm for solving the nonconvex dynamic
DEA models, to obtain cost minimum under nonconvex technologies. The validity of the …

DEA models help a DMU to detect its (in-) efficiency and to improve activities, if necessary.
Efficiency is only one economic aim for a decision-maker; however, up-or downsizing might …
