Abstract text

A system includes a first controller configured to monitor processes associated with a process facility and to generate control data for optimizing the process facility. The system also includes a second controller configured to use stochastic calculus of variations calculations to modify at least a portion of the control data. The second controller is configured to provide discrete supply chain control and optimization for the process facility and to track at least one of demand requirements and shipping requirements for product manufactured by a discrete supply chain manufacturing process. The system further includes third controllers configured to operate in accordance with the control data to control the processes and to optimize the process facility.
