Valuation of efficiency under conditions of uncertainty and subjectivity

J. Reig Mullor, M.E. Sansalvador Selles, J.A. Trigueros Pina. University Miguel Hernández

Abstract

With this paper we have intended to adapt DEA (Data Envelopment Analysis), one of the most widespread techniques in measuring efficiency. This re-formulation will be carried out under fuzzy logic, and its mathematical development will be done by using the Theory of fuzzy sets and systems. This will allow us to treat all the imprecise and subjective variables which intervene in measuring the efficiency of both public and Private sector organisations

Keywords: uncertainty, subjectivity, efficiency, DEA
