Abstract
A facilities management system is subdivided into a plurality of subsystems. The performance of the system is monitored by producing data which denotes a plurality of operational parameters for each of the subsystems. From that data, a global performance index is derived for each subsystem, thus providing an indication of each subsystem's performance. The global performance indices are employed to produce a universal performance index for the entire facilities management system. This provides a hierarchy of data which enables an operator to quickly determine the overall performance of the facilities management system and each subsystem, and if warranted the operator can step through the data to identify malfunctioning components.
Claims17
A method for monitoring performance of a facilities management system, the method comprising steps of:
- (a) subdividing the facilities management system into a plurality of subsystems;
- (b) producing numerical data denoting status of a plurality of operational parameters for each of the plurality of subsystems;
- (c) normalizing the data to produce normalized data;
- (d) for a given one of the plurality of subsystems, averaging the normalized data acquired during a period of time for a given one of the plurality of operational parameters;
- (e) repeating step (d) for all of the plurality of operational parameters for the given one of the plurality of subsystems, thereby producing a plurality of averaged data;
- (f) repeating steps (d) and (e) for all of the plurality of subsystems;
- (g) arithmetically producing a separate global performance index for each of the plurality of subsystems from the plurality of averaged data, thereby producing global performance indices;
- and
- (h) deriving a universal performance index from the global performance indices, wherein the universal performance index qualitatively denotes performance of the facilities management system.
