Abstract

A process control system uses an asset optimization reporter to collect status information of dissimilar types pertaining to the assets of a process plant from various data sources of the plant including, for example, data tools, data collectors, and data generators. This status information is used to generate reports that may be displayed to various users, including maintenance persons, process control persons and business persons. The status information may be used as the basis for further types of status information and/or be categorized in based on an assessment of relative consequence, where each category has a spectrum of status quality values between a good status quality and a relatively worse status quality. The reports are generally displayed via a user interface routine that enables users to view the status information as a graphical representation having a leg of a normalized spectrum of values for each category arranged in order of the relative consequence, the relative status quality value being identified at a point on the respective leg.
