A generalized DEA model for centralized resource allocation

Abstract

In this paper, we introduced a new generalized centralized resource allocation model which extends Lozano and Villa's and Asmild et al.'s models to a more general case. In order to uncover the sources of such total input contraction in the generalized centralized resource allocation model, we applied the structural efficiency to further decompose it into three components: the aggregate technical efficiency, the aggregate allocative efficiency and re-transferable efficiency components. The proposed models are not only flexible enough for the central decision-maker to adjust the inputs and outputs to achieve the total input contraction but also identify the sources of such total input contraction, thereby giving rise to an important interpretation and understanding of the generalized centralized resource allocation model. Finally, an empirical example is used to illustrate the approach. © 2013 Elsevier B.V. All rights reserved.
