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
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.

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.

20. A method of monitoring an entity within a process plant, wherein the process plant comprises a system hierarchy having a plurality of levels and a plurality of devices, the method comprising:
-
acquiring a plurality of use indices, each use index pertaining to the status of a device;
assigning a weighting value to each device, the weighting value pertaining to the priority of the device among the plurality of devices;
combining the use index and weighting values assigned to each of the devices; and
creating an aggregate use index at each level of the system hierarchy from the combined use indices and weighting values. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A system for displaying an aggregate use indices for a process plant having a plurality of entities, the system comprising:
-
a processor;
a display;
a database adapted to store use indices for each of the plurality of entities, each use index pertaining to the status of the entity and adapted to store weighting values for each of the plurality of entities, each weighting value pertaining to the importance of the entity among the plurality of entities;
a routine adapted to be executed by the processor which stores a representation corresponding to a higher level entity plurality of entities in the database, the higher level entity comprises the plurality of entities;
a routine adapted to be executed by the processor which generates an aggregate use index from a combination of the plurality of use indices and the plurality of weighting values, the aggregate use index pertaining to the status of the higher level entity; and
a routine adapted to be executed by the processor which displays the representation and which displays the aggregate use index proximately to the corresponding representation. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40)
