A method for controlling the mode of operation of the in a refinery or a petrochemical industry complex systems provided

摘要

The present invention relates to a method and a tool for control of the mode of operation of the in a refinery or a petrochemical industry complex systems provided. In this case, a division into a planning plane, a scheduling - plane and a process control plane. The generated in the scheduling - plane data which the process control plane be made available as reference variables, are based on a decomposition of a finishing system in at least two individual systems and a numerical optimization carried out in each single system of variable. Furthermore, a coordination of the optimization of the fact that in any one of the individual systems during the optimization of the factors determined be used in the other single system.
