Abstract: A process control system and method for use in controlling a process, which has a plurality of process variables, including a plurality of manipulatable process variables, to achieve at least one performance measure, the system comprising: an optimization module for predicting values for at least ones of the manipulatable process variables to achieve target values for the at least one performance measure in accordance with a fuzzy rule set, each fuzzy rule including a plurality of decision points corresponding to split variables relating to the process variables and a plurality of outcomes, wherein the at least one fuzzy rule of the fuzzy rule set enables values to be predicted for the manipulatable process variables for defined values of the at least one performance measure.

Abstract: A process control system and method for use in controlling operation of a process in response to identification of one or more events, where each event is a condition relating to one or more process variables for the process and has a determined association with one or more other events, the system comprising: an event control module which is operative to log from the process the one or more process variables which are attributed to the one or more events, and provide a control indication in response to each identified event, wherein the control indication identifies the event as one of a cause event or an effect event and the one or more associated other events as effect events for a cause event or cause events for an effect event.
