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

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

Elasticity, the scale effect, and marginal rates are computed in technical efficiency analysis of complex systems by parametric optimization algorithms developed by the authors. It is shown that the scale effect evaluated at the vertices of a polyhed

The qualitative characterisation of returns to scale in DEA has been a research issue the last decade. However, quantitative information provides the ultimate information. This paper presents two ways of obtaining numerical values of scale elasticity

In this paper, we establish relations between the sets of input and output boundaries, a set of weakly Pareto-efficient points and the boundary of the production possibility set. Theoretical results presented in the paper are illustrated by examples.

The aim of the paper is to present and substantiate a technique to visualize DEA modelling results without any loss of mathematical rigour. The proposed family of parametric optimization methods allows one to construct an intersection of the multidim

The financial situation of transitional period in Russia makes companies in the country economize their resources, and as a consequence increase their efficiency. Data Envelopment Analysis (DEA) proposed by A. Charnes and W. Cooper is a powerful appr
