ROOT CAUSE DIAGNOSTICS OF ABERRATIONS IN A CONTROLLED PROCESS

摘要

An industrial process diagnostic apparatus (100) is provided which can identify a source, or "root cause", of an aberration in an industrial process. A plurality of process configuration models (112) are provided which each represent a physical (or actual) implementation of an industrial process. One of the plurality of models is selected and diagnostics performed on the process using the selected model and at least one process signal related to the process. Based upon the diagnostics, a root cause of the aberration is determined.
