However, it cannot distinguish the differences between efficient DMUs
5], PTE is the efficiency of hospital systems and management which is affected by factors such as management and the technology of DMUs
Hierarchical Clustering was used, grouping DMUs
by degree of similarity, taking into consideration, in this research, the averages and variances for all variables selected for the model.
Vale ressaltar que as DMUs
podem ser grupos empresariais, empresas, unidades administrativas, hospitais, universidades, cidades, departamentos, regioes, paises, dentre outros, os quais tornam os insumos em produtos (Mariano, Almeida, & Rebelatto, 2006; Cooper, Seiford, & Zhu, 2011).
The selection of a suitable projection point is a very important procedure in DEA for evaluating the potential performance of each assessed unit, as it can provide key benchmarking information on how inefficient DMUs
could reach the status of efficient.
Como forma de validar as eficiencias encontradas pela modelagem DEA atraves das DMUs
artificiais, propoe-se uma comparacao destes resultados com os resultados encontrados atraves da utilizacao da medida Omega (Keating e Shadwick, 2002) atraves da correlacao de Spearman.
The results of scale efficiency, pure technical efficiency and slacks are presented as the simple average of all DMUs
for each year for the period 2005-2015.
Moreover, in order to consider more carefully the homogeneity issue and to explore whether the subject mix might adequately affect and explain the efficiency differentials between DMUs
, we divide both departments and faculties, according to their characteristics, into two large groups, namely the ST sector and the HSS sector.
Grounded in the concept of relative efficiency, the DEA method is especially suitable for the relative efficiency evaluation of DMUs
involving multiple input and output indicators .
j] is a (n x 1) column vector of constants and indicate benchmarked DMUs
En el trabajo citado se fundamenta matematicamente, sobre un modelo DEA modificado, las condiciones que permiten determinar hasta que punto una DMU
evaluada, con eficiencia relativa igual a la unidad, se mantiene eficiente ante potenciales desmejoras en sus entradas/salidas y potenciales mejoras en las entradas/salidas de las restantes DMUs
Leaving school aged 18, he studied music at Newcastle University, where he was awarded a DMus
and a MLitt degree, based on his thesis on the life and career of the great Dennis Brain.
