摘要： A system and method for coordinating advanced process control and real-time optimization of a manufacturing process are provided. The system and method receive process data and economic data corresponding to the manufacturing process to be controlled and optimized. Based on the process data, the economic data and a nonlinear steady-state model of the process, an economic objective function is calculated by a real-time optimization module. A reduced-order non-linear approximation of the economic objective function is thereafter calculated by the real-time optimization module and transmitted to an advanced process control module. The advanced process control module utilizes the reduced-order non-linear approximation of the economic objective function to control the manufacturing process towards the constrained economic optimum.

摘要： A system and method of creating and using a graphical task scheduler. A Graphical User Interface (GUI) allows a user to graphically build a real time flow task scheduler by providing a “click & drag” functional palette which contains graphical flow chart elements. By creating this graphical flow chart, the user is able to associate a plant layout, or any subpart of the entire plant, to its associated mathematical model. With a graphical flow chart, the user can define one or more exit branches for each task. For tasks with more than one exit branch, the user can specify the conditions causing the sequence to use each branch. Once the flow chart is set up, it can be used as a sequence editor or scheduler. The sequence editor defines the sequence of tasks that will be performed by an on-line application, such as optimization, and also allows scheduling of the on-line application at specific times or periodic intervals. The scheduler controls the running of each sequence based on the scheduling information. Once a plant has been optimized by the graphical task scheduler, the optimized data may be used to control plant operations.
