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 …

Purpose The purpose of this paper is to provide an outline of the major contributions in the
literature on the determination of the least distance in data envelopment analysis (DEA). The …

Within the framework of data envelopment analysis (DEA) methodology, the problem of
determining the closest targets on the efficient frontier is receiving increased attention from …

Determining the least distance to the efficient frontier for estimating technical inefficiency,
with the consequent determination of closest targets, has been one of the relevant issues in …

In this paper we use data from OECD countries participating in PISA 2012 to assess the
efficiency of schools in a cross-country framework. In the analysis, and in contrast to …

The determination of closest efficient targets has attracted increasing interest of researchers
in recent Data Envelopment Analysis (DEA) literature. Several methods have been …

This paper is concerned with optimal directions in the directional distance function in data
envelopment analysis. It is shown that the vector pointing in the direction that minimizes the …

In DEA, there are two frameworks for efficiency assessment and targeting: the greatest and
the least distance framework. The greatest distance framework provides us with the efficient …

In this paper the smallest improvement DEA approach to general networks of processes is
proposed. The corresponding projection direction is endogenously computed by the model …

The benchmarking information targets based on Data envelopment analysis (DEA) are
commonly classified into two groups: the farthest targets and the closest targets. Many …
