Abstract

El sistema de abastecimiento de medicamentos en atención primaria de salud en Chile posee un único proveedor a nivel nacional y no considera multiniveles de demanda para el cálculo del aprovisionamiento, generando superávit de inventario. El presente trabajo propone una política de abastecimiento de revisión periódica mediante un pronóstico probabilístico de demanda, modelando su estructura de dependencia en forma individual y mediante cópulas bivariadas, coordinando los multiniveles y minimizando los costos. El estudio se llevó acabo en una muestra de 104 medicamentos abastecidos durante 3 anos en un centro de salud familiar chileno. Los resultados generados muestran que la política propuesta disminuiría semanalmente en un 8,22% los costos de compra, en un 95,47% los costos de ordenar y en un 54,6% los costos totales
