There are some specific features of the non-radial DEA (data envelopment analysis) models which cause some problems under the returns to scale measurement. In the scientific literature on DEA, some methods were suggested to deal with the returns to scale measurement in the non-radial DEA models....

Applications of the DEA models show that inadequate results may arise in some cases, two of these inadequacies being: a) too many efficient units may appear in some DEA models; b) a DEA model may show an inefficient unit from the point of view of experts as an efficient one. The purpose of this...

The purpose of this dissertation is to present an overview of the operational and financial performance of airports in Europe. In benchmarking studies, airports are assessed and compared with other airports based on key indicators from a technical and economic point of view. The interest lies...

The purpose of this study is to evaluate the governance efficiencies of the water supply systems by applying data envelopment analysis (DEA) to 33 Palestinian municipalities. We demonstrate that DEA can be a useful tool to assess the relative efficiencies of water supply systems and to establish...

We study the United Nations Organization's Kyoto Protocol nations to address two questions. First of all, what are the environmental production efficiency rankings of these nations? Secondly, is there a relationship between a nation's ratification status and its environmental production...

What is the origin of Strategic Management leading towards national Welfare planning, development and optimisation all over the World? This question opens a "Pandora's Box". It is significant that it is a key question to open up the knowledge of a world of ignorance, with some believing that...

This article presents a novel combination of robust optimization developed in mathematical programming, and robust parameter design developed in statistical quality control. Robust parameter design uses metamodels estimated from experiments with both controllable and environmental inputs...

Standard portfolio construction models are based on the implicit assumption that all information relevant to making investment choices is probabilizable. However, both empirical behaviors of market participants and the increased success of approaches like risk parity underly an implicit...

Research & development (R&D) performance has been a competitive advantage for high-tech industries. This paper presents an empirical study in which we used Data Envelopment Analysis (DEA) to evaluate the R&D performance of 31 computers and peripherals firms located at Hsinchu Science-based...
