A system and method for performing modeling, prediction, optimization and control, which would permit what is, described herein as embedded alarm control. In the proposed method of embedding alarm control, the alarm limits are used to constrain the controlled variables dynamically such that the controller actions are affected to minimize and prevent alarm limit violations in addition to the constraints commonly included. It is proposed in the present invention that the alarm limits be incorporated as part of optimization and constrained control action calculation in a model predictive control. As an exemplary case, this method of incorporation of alarm limits within optimization and control is described and the results obtained from it are presented. The embedding of alarm control within optimization and control would not only directly minimize number of alarms from becoming active from improved control but also provide additional capabilities whereby selectively alarms limits violations can be tuned to reduce the number of alarms without compromising on either product quality control or safety violations.
