PLANT OPERATING POINT DETERMINATION BY INTEGRATING PROFIT PROFILE AND RISK PROFILE
First Claim
1. A method for controlling physical processes, comprising:
- providing a process model for a physical process run by a processing plant including a plurality of controlled process variables, said process model representing an interaction between said plurality of controlled process variables and providing a variability measure for at least a portion of said plurality of controlled process variables;
using said process model with software run on a computing device, simulating an updated operating point including an updated value or updated range for at least one selected controlled process variable from said portion of said plurality of controlled process variables, said simulating generating a future risk profile and a future profit profile for said selected controlled process variable, andgenerating risk/profit profile information for said selected controlled process variable, said risk/profit profile information combining information from said future risk profile together with information from said future profit profile into at least one of a combined text, numeric, and graphical representation which includes an alarm limit for said selected controlled process variable.

Abstract
A method for controlling physical processes includes providing a process model for a physical process run by a processing plant, where the process model represents an interaction between a plurality of controlled process variables and provides a variability measure for at least a portion of the controlled process variables. The process model is used with software run on a computing device to simulate an updated operating point including an updated value or updated range for at least one selected controlled process variable, where the simulation generates a future risk profile and future profit profile for the selected controlled process variable. Risk/profit profile information is generated for the selected controlled process variable from the future risk profile together with information from the future profit profile into at least one of a combined text, numeric, and graphical representation which includes an alarm limit for the selected controlled process variable.
