To illustrate the model performance, an average traditional farm was analyzed, some technical changes tested and, finally, two weather conditions simulated to estimate the influence of weather on resource allocation.  aBrazil  aprices  asheep  aAnálise  aCaprino  aComercio  aOvino  aPreço  aProdução  aSistema de Produção  aAnalysis  aAspecto econômico  aBrasil  aCeara  aCommerce  aEconomic situation  aGoat  aNordeste  aNortheast  aProduction  aProduction System  aRegião nordeste  aSistema  aSystem
