The main purpose of this study is to provide a comparative analysis of several possible approaches to applying data envelopment analysis (DEA) in the case where some decision making units (DMUs) in the original sample have negative system outputs. In

Non-convex Free Disposal Hull (FDH) model was proposed in the scientific literature at the end of the 20th century for performance measurement of complex multidimensional production units. FDH model was proposed almost simultaneously with the DEA (Da

In data envelopment analysis, methods for constructing sections of the frontier have been recently proposed to visualize the production possibility set. The aim of this paper is to develop, prove and test the methods for the visualization of producti

The free disposal hull (FDH) model of production technology assumes free disposability of all inputs and outputs, but does not make any convexity assumptions. In this paper, we develop an algorithm for the reconstruction of the frontier of the FDH te

It is well known that many inefficient units are projected onto the weakly efficient parts of the frontier under computing efficiency scores. However, according to the data envelopment analysis approach, the efficiency score of inefficient units has

Computational experiments with DEA models show that many inefficient units are projected onto the weakly efficient parts of the frontier when efficiency scores are computed. This fact disagrees with the main concept of the DEA approach, since efficie
