<p><P>PROBLEM TO BE SOLVED: To monitor, on-line operation of a process in a processing plant provided with a processing process control system for controlling the process in connection with process measurements indicative of the operation of the process. <P>SOLUTION: This system and method for on-line monitoring of the operation of a process in connection with process measurements indicative of the operation of the process. In some cases, the operation of the process is simulated to generate model data indicative of a simulated representation of the operation of the process and based on the process measurements. A multivariate statistical analysis of the operation of the process is implemented based on the model data and the process measurements. The output data transmitted from the multivariate statistical analysis may then be evaluated during the operation of the process to enable the on-line monitoring of the process involving, for instance, fault detection via classification analysis of the output data. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
