Última EVALUATING ALTERNATIVE FARMING SYSTEMS: A FUZZY MADM APPROACH AgEcon Marks, Leonie A.; Dunn, Elizabeth G.. This paper develops a decision support method that integrates measures of achievement in the economic, environmental, and social aspects of farming. The decision support method combines multiple attribute decision making (MADM) with fuzzy logic. The fuzzy MADM model fully ranks decision alternatives relative to the preferences of decision makers and overcomes several problems inherent in other MADM approaches. It is concluded that fuzzy MADM can improve decision making on the farm.

Ano: 1999 URL: http://purl.umn.edu/21642 fuzzy: A program for performing qualitative comparative analyses (QCA) in Stata AgEcon Longest, Kyle C.; Vaisey, Stephen. Qualitative comparative analysis (QCA) is an increasingly popular analytic strategy, with applications to numerous empirical fields. This article briefly discusses the substantive motivation and technical details of QCA, as well as fuzzy-set QCA, followed by an in-depth discussion of how the new program fuzzy performs these techniques in Stata. An empirical example is presented that demonstrates the full suite of tools contained within fuzzy, including creating configurations, performing a series of statistical tests of the configurations, and reducing the identified configurations.

Ano: 2008 URL: http://purl.umn.edu/120930 Fuzzy expert system in the prediction of neonatal resuscitation BJMBR Reis,M.A.M.; Ortega,N.R.S.; Silveira,P.S.P.. In view of the importance of anticipating the occurrence of critical situations in medicine, we propose the use of a fuzzy expert system to predict the need for advanced neonatal resuscitation efforts in the delivery room. This system relates the maternal medical, obstetric and neonatal characteristics to the clinical conditions of the newborn, providing a risk measurement of need of advanced neonatal resuscitation measures. It is structured as a fuzzy composition developed on the basis of the subjective perception of danger of nine neonatologists facing 61 antenatal and intrapartum clinical situations which provide a degree of association with the risk of occurrence of perinatal asphyxia. The resulting relational matrix describes the association between...

Ano: 2004 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-879X2004000500018 A fuzzy system for cloacal temperature prediction of broiler chickens Ciência Rural Ferreira,Leandro; Yanagi Junior,Tadayuki; Lacerda,Wilian Soares; Rabelo,Giovanni Francisco. Cloacal temperature (CT) of broiler chickens is an important parameter to classify its comfort status; therefore its prediction can be used as decision support to turn on acclimatization systems. The aim of this research was to develop and validate a system using the fuzzy set theory for CT prediction of broiler chickens. The fuzzy system was developed based on three input variables: air temperature (T), relative humidity (RH) and air velocity (V). The output variable was the CT. The fuzzy inference system was performed via Mamdani's method which consisted in 48 rules. The defuzzification was done using center of gravity method. The fuzzy system was developed using MAPLE® 8. Experimental results, used for validation, showed that the average standard... Tipo: Info:eu-repo/semantics/article Palavras-chave: Expert system; Fuzzy sets; Thermal environment.
