<p>In methods and systems that may facilitate detecting abnormal operation in a process plant, values of a plurality of process variables may be analyzed to determine whether any of a plurality of faults associated with the process plant exist. If one or more faults are detected, one or more indicators may be generated. Analyzing the values of the plurality of process variables may include utilizing a coefficient matrix. The coefficient matrix may be generated based on process variable data corresponding to the known occurrences of faults.</p> |
