Abstract

La gestión óptima de las plantas de proceso normalmente se lleva a cabo en una capa de optimización en tiempo real (Real Time Optimization, RTO) que actúa sobre la capa de control y que toma decisiones considerando objetivos económicos en base a un  modelo del proceso, normalmente estacionario. Sin embargo, dicha operación óptima no está garantizada debido a la presencia de incertidumbre entre el modelo usado para la toma de decisiones y el proceso real. Con la idea de conducir el proceso a su punto de operación óptimo usando un modelo que se sabe incierto o erróneo, surge la metodología de adaptación de modificadores (Modifier Adaptation o MA). En dicha metodología, el problema de optimización económica de la capa RTO es modificado mediante unos términos correctores, conocidos como modificadores, estimados a partir de medidas de la planta, con el objetivo de conducir el proceso a su punto de operación óptimo. El presente artículo hace una revisión de las técnicas desarrolladas hasta el momento dentro de la metodología MA analizando sus características y modos de implementación.
