It is usual to rank the participating countries in the Olympic Games in accordance with the number of medals they have won. An alternative ranking is suggested in this paper. This ranking is based on each country's ability to win medals in relation to its available resources. This is an efficiency that can be measured with the help of Data Envelopment(More)
This paper presents an application of the integration between Geographical Information Systems (GIS) and Multi-Criteria Decision Analysis (MCDA) to aid spatial decisions. We present a hypothetical case study to illustrate the GIS–MCDA integration: the selection of the best municipal district of Rio de Janeiro State, Brazil, in relation to the quality of(More)
Electrical energy must be supplied in enough amount but with adequate quality. One of the components of electrical energy quality is the harmonic distortion. In this paper, we show an alternative way to measure distortion, mixing Data Envelopment Analysis (DEA) and Fourier Analysis. The technique here presented is specially useful for comparative analysis(More)
We define and model the research production at Embrapa, the major Brazilian institution responsible for applied agricultural research. The main theoretical framework is Data Envelopment Analysis – DEA. We explore the economic interpretation and the statistical properties of these models to compute confidence intervals for output oriented efficiency(More)
