Abstract
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.

21. An apparatus comprising:
-
a first module configured to perform a scheduled to go function to keep track of inventory releases, the inventory releases made to satisfy a specified schedule for a product in a discrete supply chain manufacturing process; and a second module configured to perform a target release function that uses unfilled releases and a number of control intervals remaining in a current period to calculate a target value for an intervals release; wherein the first module is configured to use a disturbance variable to represent product orders, a controlled variable to represent unfilled product orders, and at least one manipulated variable to fill product orders; and wherein the second module is configured to use one of a manipulated variable and a controlled variable to specify the target value.
