Generación y selección óptima de opciones de destino de hornadas en fábricas siderúrgicas // Optimal generation and selection hits destination options in steel making factorys
Abstract
A partir del análisis sistémico de la función de operación de la producción en fábricas siderúrgicas, se formula el modelo matemático conceptual de la tarea de selección de hornadas a utilizar por lotes de entrega a los clientes de la producción terminada de talleres siderúrgicos. Este modelo se descompone en sub-modelos de generación de opciones de destino, por hornadas en proceso, como una tarea de optimización estocástica discreta, y de selección de las hornadas a utilizar para cada uno de los lotes requeridos por el servicio de ventas, como una tarea de optimización en variables booleanas. Se elaboran y comparan entre sí diferentes modelos de descripción de las propiedades mecánicas de las hornadas y se propone el esquema solución a la tarea de generación de opciones por el método de búsqueda exhaustiva. El modelado desarrollado queda disponible para su utilización práctica por los servicios de despacho de empresas siderúrgicas.Palabras claves: operación de la producción siderúrgica; toma de decisiones; descomposición de tareas de optimización; sistemas de ingeniería.

Abstract
Starting from the systemic analysis of the operation production function in steel factories, the conceptual mathematical model is formulated of the heats selection to be used for the lots delivery to the clients of the finished production of steel shops. This model breaks down in sub-models of the destination of options generation of heats in production process, as a discrete stochastic optimization task of the selection of the heats to be used for each one of the lots required by the sales service, as an optimization task in boolean variables. Have been elaborated and compared different mechanical properties description of the heats models and proposed a solution outline solution of the options generation task by the exhaustive search method. The modeling work developed is available for it practical use by the despatching services of the steel companies.Key words: operation of the steel making production; decision making; decomposition of optimization tasks; engineering systems.
