Aggregation of asset use indices within a process plant
First Claim
1. A method of monitoring an entity within a process plant wherein the entity includes a plurality of lower level entities, the method comprising:
- acquiring a plurality of use indices, each use index pertaining to status information regarding one of the plurality of lower level entities;
acquiring a plurality of weighting values, each weighting value pertaining to the importance of a lower level entity among the plurality of lower level entities, and wherein each weighting value is based on the impact of the lower level entity on the entity and the frequency of failure of the lower level entity;
creating an aggregate use index from a combination of the lower level use indices and weighting values, wherein the aggregate use index represents status information regarding the entity; and
storing the aggregate use index in a computer readable medium.

Abstract
A method of monitoring an entity within a process plant wherein the entity includes a plurality of lower level entities, includes acquiring a plurality of use indices, acquiring a plurality of weighting values, and creating an aggregate use index from a combination of the lower level use indices and weighting values, wherein the aggregate use index represents status information regarding the entity. Each use index pertains to status information regarding one of the plurality of lower level entities, and each weighting value pertains to the importance of a lower level entity among the plurality of lower level entities.
