A performance measure to support decision-making in Agricultural Research Center in Brazil. Author(s): SOUZA, G. da S. e; GOMES, E. G. The assessment of productive efficiency of a public research institution is of fundamental importance for its administration. A better management of available resources may be accompliched if managers... ... Repository: BDPA Publication year: 2015
Cluster analysis in degraded areas by erosion in the Nazareno (MG) region. Author(s): CASSARO, R.; FERREIRA, R. R. M.; FERREIRA, V. R. M.; RODRIGUES, V. G. S. Abstract: When analyzing a database, summarize collected information is the analyst main challenge. In many cases, when you have a large number of data, it may be of interest to create groups. A clust... ... Repository: BDPA Publication year: 2021
A proposal for building domain topic taxonomies. Author(s): MOURA, M. F.; MARCACINI, R. M.; NOGUEIRA, B. M.; CONRADO, M. da S.; REZENDE, S. O. In this work a methodology to aid the process of organizing text collections is proposed, aiming to reflect exactly the existent and recoverable publications in a specific domain.

A geometrical approach for fuzzy DEA frontiers. Author(s): BIONDI NETO, L.; MELLO, J. C. C. B. S. de; MEZA, L. A.; GOMES, E. G. Interval DEA frontiers are here used in situation where one input or output is subject to uncertainty in its measurement and is presented as an interval data. We built an efficient frontier without an... ... Repository: BDPA Publication year: 2009
