The paper states empirical results of inter-branch research of efficiency of the industry of Ukraine as the first and one of the basic stages of the three-level analysis of efficiency (Goncharuk 2007). By results of the analysis groups of high, low and medium efficient industries are determined....

In this paper we use the flexibility of Surface Measure of Overall Performance (SMOP) and Data Envelopment Analysis (DEA) ranking methods to analyze the relative performance of each individual Spanish airport, and to fully rank both efficient, as well as inefficient airports. Most airports have...

Data Envelopment Analysis (DEA) models have been intensively used for measuring efficiency in a variety of contexts. More recently, the inclusion of undesirable outputs has extended their use to analyze relevant fields such as environmental efficiency. In this context, Slacks-Based Measure (SBM)...

Conventional data envelopment analysis (DEA) methods assume that input and output variables are continuous. However, in many real managerial cases, some inputs and/or outputs can only take integer values. Simply rounding the performance targets to the nearest integers can lead to misleading...

This article presents the super-efficiency model (SE-CCR), which is one of the most important modifications of the classic CCR model, and describes the main analytical capabilities of the SE-CCR model. Some of these capabilities are direct equivalents to the capabilities of the CCR model, e.g....

We propose simple estimation of the location parameter for a density that is unbounded at the mode. The estimator maximizes a modified likelihood in which the singular term in the full likelihood is left out, whenever the parameter value approaches a neighborhood of the singularity location. The...

Some models are presented in this paper which extend the concept of measuring superefficiency to the useful case of variable returns-to-scales (VRS), thus enabling the ranking of efficient as well as inefficient units. Two models, namely the Universal Radial Model and the Universal Additive...

Efficiency scores of the National Innovation System (NIS) for 22 countries, including the BRICS, G7, are calculated with the Data Envelopment Analysis (DEA). Relevant factors that may affect the innovation system efficiency are summarized based on the NIS Approach and the New Growth Theory....

In this study, the authors used the variable-benchmark data envelopment analysis method to study the innovation performance of an enterprise. In the proposed model, information technology, value proposition, value study, and team activities were the input factors, and product model change,...

This article uses an original three-phase approach for empirical assessment and comparative evaluation of the efficiency of university technology transfer. It is based on analysis of inputs and outputs of a disclosure phase followed by a value-add phase and a final license phase, using a...
