Variations on the theme of slacks-based measure of efficiency in DEA
Tone, Kaoru - National Graduate Institute for Policy Studies (GRIPS) - 2008
In DEA, there are typically two schemes for measuring efficiency of DMUs; radial and non-radial. Radial models assume … efficiency measure, called slacks-based measure (SBM). In this paper, we point out shortcomings of the SBM and propose 4 variants … of the SBM model. The original SBM model evaluates efficiency of DMUs referring to the furthest frontier point within a …

The use of percentiles and percentile rank classes in the analysis of bibliometric data: Opportunities and limits
Bornmann, Lutz; Leydesdorff, Loet; Mutz, Rüdiger - In: Journal of Informetrics 7 (2013) 1, pp. 158-165
Percentiles have been established in bibliometrics as an important alternative to mean-based indicators for obtaining a normalized citation impact of publications. Percentiles have a number of advantages over standard bibliometric indicators used frequently: for example, their calculation is not...

FINDING THE REFERENCE SET OF A DECISION MAKING UNIT
JAHANSHAHLOO, G. R.; SHIRZADI, A.; MIRDEHGHAN, S. M. - In: Asia-Pacific Journal of Operational Research (APJOR) 25 (2008) 04, pp. 563-573
In this paper we propose a method for finding the reference set of a decision making unit (DMU), without chasing down all alternative optimal solutions of the envelopment form, which is a strong degenerate problem. The reference set is useful as a benchmark for an inefficient DMU, for...
