Plant Process Management System with Normalized Asset Health

摘要

A process plant management system with asset health normalization and aggregation. Aspects of the system include asset monitoring components that sense operating parameters and determine the condition of assets using a number of disparate asset condition assessment methodologies based on those parameters. The system calculates normalized component health scores from the reported asset condition information and evaluates the normalized component health scores to produce an overall asset health score for each asset. The system maintains a hierarchical representation that organizes assets using physical and logical relationships. The system generates virtual health scores for parent objects in the hierarchy from the health scores of the children of each parent object.

1. An apparatus for evaluating health for a plurality of assets in a plant process management system, the apparatus comprising:
a. an asset manager organizing the plurality of assets into a hierarchical arrangement of parent objects and child objects; b. a plurality of asset monitoring components, each asset monitoring component comprising a sensor operatively connected to one of the assets, each asset monitoring component determining a condition value for the asset based on a parameter measured using the sensor, and c. a health normalization module calculating parametric health scores based on the asset condition values determined by the asset monitoring components, the parametric health scores normalized to a selected range of values.
