Análise Multicritério De Materiais Para a Síntese De Catalisadores Automotivos

Abstract: resumo: Este artigo estuda o emprego da composição probabilística para avaliar o desempenho de catalisadores automotivos com diferentes composições de materiais. Foram comparados catalisadores à base de óxidos mistos de cério e zircônio impregnados ou não com paládio, e aditivados ou não com alumina impregnada com lantânio. Cada catalisador foi analisado quanto à desativação térmica segundo diferentes condições de envelhecimento. A comparação foi baseada em sete critérios, nos quais cada um dos catalisadores r… Show more

“…The preferences of appraisers in multi-criteria issues are modeled with empirical probabilities, without assuming a random behavior by continuous probability distributions as proposed by Sant'Anna (2015a) and Abbas (2006). A summary review of the literature indicates that CPP has modeled issues with uniform probability distributions (Sant'Anna & Conde, 2011;Sant'Anna et al, 2012a), normal (Sant'Anna, 2013;Sant'Anna et al, 2015a), triangular (Sant'Anna & Silva, 2011;Treinta et al, 2014), Pareto (Caillaux et al, 2011;Sant'Anna & Mello, 2012) and Beta (Maciel, 2015;Sant'Anna, 2015b;Sant'Anna et al, 2015b), with applications in the most diverse areas of knowledge. In this context, the use of empirical probabilities constitutes a contribution for applying the CPP method.…”
