Resumo: The center composite design is symmetrical, of second order, and constituted of two parts: the factorial 2k, with one or more central points, and the axial. The aim of this research has been to verify, through simulations, the design type in field experiments, for instance, in Agronomy; in laboratory bioassays in Phytopathology, Virology and Entomology with variation coefficient not superior to 6%; and in chemical industry experiments with variation coefficient inferior to 3%. It has been verified that its use is not recommended when variation coefficient is over 6% when best points are expected; likewise, in field research, even with repetition of treatments, since responses and points do not meet expected values

O objetivo deste trabalho foi o de verificar, com simulações, a viabilidade do uso desse tipo de delineamento nas áreas de pesquisas de campo, como em Agronomia; em laboratórios de Fitopatologia, Virologia e Entomologia, em pesquisas onde o coeficiente de variação não é superior a 6%; e na indústria química, com coeficiente de variação abaixo de 3%. Através das simulações, verificou-se que seu uso não é conveniente em áreas de pesquisa, cujo coeficiente de variação seja superior a 6%, quando se buscam estimativas de resposta e dos pontos ótimos e também em pesquisas de campo, como na Agronomia, mesmo quando se repetem todos os tratamentos, pois se observam muitas respostas e pontos bem longe do esperadoUniversidade Estadual De Maringá2008-05-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/279510.4025/actascitechnol.v23i0.2795Acta Scientiarum.
