Este trabajo trata el problema de la determinación de los tamaños muestrales en el muestreo estratificado. Para situaciones en que se pretende finalizar el proceso de muestreo en el menor tiempo posible trabajando simultáneamente en los estratos, formulamos un modelo que minimiza el máximo de los tiempos empleados en cada estrato, acotando el error cometido en la estimación, y obtenemos un método exacto que nos proporciona una expresión analítica para los tamaños muestrales, tanto en el caso de la estimación de una como de varias características.
This paper treats the problem of the allocation of sample sizes to strata in stratified sample surveys. Considering situations in which the objetive is to finish the sampling as soon as possible, when it is possible to work simoultaneously in the strata, we propose a model that minimizes maximum time spent in each strata, at the same time that fixes estimation precision. We obtain an exact method that leads to an analytic expression of the sample sizes for the general problem of estimating several characteristics in a sample survey.
