1. A computer-implemented method of controlling the optimization of a complex process having associated operational variables and process outputs, the method comprising the steps of:
- defining a series of corrective actions associated with the process;
modeling a relationship between the operational variables and the process outputs measured over time;
for each corrective action, computing a risk reduction associated with the process outputs; and
determining an urgency metric, based at least in part on the risk reductions, for each of the corrective actions.

11. A system for controlling the optimization of a complex process having associated operational variables and process outputs, the system comprising:
-
(a) a process monitor for monitoring process outputs over time; and
(b) a data processing device for receiving, from the process monitor, data indicative of values of the process outputs, and determining the urgency levels for one or more corrective actions based on (i) a risk reduction associated with the process outputs, and (ii) a relationship between the operational variables and the process outputs. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
