Set-to-set maps in efficiency analysis of complex systems

Autor: Vladimir E. Krivonozhko, O. B. Utkin, M. M. Safin, A. V. Lychev

Publikováno v: Computational Mathematics and Modeling. 21:425-439

The article examines various set-to-set maps used in activity analysis of complex systems. The properties of these maps are then applied to compare various methods currently used for activity analysis of complex systems. It is shown that the popular

On some generalization of the DEA models

Autor: Andrey V. Lychev, O. B. Utkin, Vladimir E. Krivonozhko, M. M. Safin

Publikováno v: Journal of the Operational Research Society. 60:1518-1527

Inadequate results may arise in some instances of DEA model applications. For example, a data envelopment analysis (DEA) model may show ‘a notoriously inefficient unit’ as an efficient one. In addition, too many efficient units may appear in some
