Abstract in Portuguese
Neste trabalho apresentamos o método de amostragem intencional via otimização. Tal método baseia-se na fundamentação de que devemos controlar a seleção amostral sempre que houver conhecimento suficiente para garantir boas inferências de quantidades conhecidas e de alguma forma correlacionadas com aquelas desconhecidas e de interesse. Para a resolução dos problemas de otimização foram utilizadas técnicas de programação linear. Três aplicações foram apresentadas e em todas elas notou-se que o procedimento de amostragem intencional produziu amostras com bom balanceamento entre as composições amostrais e de referência.

Abstract in English
In this work we present the method of intentional sampling by optimization. Such method is based on the fact that we must control the sampling selection whenever we have enough knowledge to guarantee good inferences of known quantities and somehow correlated with those interesting and unknown ones. Linear programming techniques were used to solve the optimization problems. Three applications were presented and all of them produced samples with good balancing properties related to the referenced populations.
