In this study, a multi-criteria data envelopment analysis (MCDEA) model, used in the literature to moderate the homogeneity of weights dispersion, is solved using pre-emptive goal programming. The MCDEA model solved using pre-emptive goal programming gives the same relative efficiency as the classical DEA model while it improves the homogeneity of input-output weights. This conclusion is confirmed by the computational results obtained when the two models are applied to a real data set relative to the socio-economic performances of European countries and to randomly generated instances with various numbers of decision making units, inputs and outputs.

This broadens the field of application of the DEA methodology.

    Problem statement: Conventional Data Envelopment Analysis (DEA) helps decision makers to discriminate between efficient and inefficient Decision Making Units (DMUs). However, DEA does not provide more information about the efficient DMUs. Super-efficiency DEA model can be used in ranking the...

    It is shown that optima] dual solutions for the Additive and the BCC models are not invariant under translation. In particular, this implies that the Ali-Seiford (1990) and Pastor (in chapter 3) results on translations apply only to the envelopment portion of DEA and thus do not, in particular,...

For firms with more than one plant, Koopmans proposes a procedure for deriving the short-run production frontier for each firm. Modifying his...
