Abstract

A method and system for operating a facility having a plurality of equipment combinations wherein each equipment combination is operating interactively with at least one of another of the plurality of equipment combination is provided. The method includes receiving, in real-time, for each of the plurality of equipment combinations, a plurality of measured process parameters, determining at least one derived quantity from the plurality of measured process parameters, and recommending a change to an equipment operation based on the measured process parameters and the derived quantities.

Claims

1. A method for operating a facility having a plurality of equipment combinations, each equipment combination is operable interactively with at least one other equipment combination, said method comprising:

receiving a plurality of measured process parameters, in real-time, for each of the plurality of equipment combinations, wherein the equipment combinations include at least a driver machine and a driven machine;

determining, using a computer, at least one derived quantity from at least one measured process parameter associated with at least a first of the equipment combinations and from at least one measured process parameter associated with at least a second of the equipment combinations, wherein the at least one derived quantity is associated with at least one of the plurality of equipment combinations and is compared to a measured process parameter to verify an operability of at least one sensor; and

recommending a change to an equipment operation based on the measured process parameters and the at least one derived quantity.

2. A method in accordance with claim 1 wherein receiving a plurality of measured process parameters further comprises receiving measured process parameters intermittently.

3. A method in accordance with claim 1 wherein determining at least one derived quantity comprises determining at least one derived quantity in real-time.

4. A method in accordance with claim 1 wherein determining at least one derived quantity comprises:

receiving measured process parameters associated with each of the at least one derived quantity; and

determining each of the at least one derived quantity using at least one rule from a rule set.

5. A method in accordance with claim 1 further comprising generating a rule set for an equipment combination using at least one of the measured process parameters, the at least one derived quantity, a design specification for the equipment combination, a maintenance history of the equipment combination, and an expert database.

6. A method in accordance with claim 1 further comprising receiving technical information from an online interactive technical manual for at least one equipment combination.

7. A method in accordance with claim 1 further comprising receiving measured process parameters from a remote input/output device.

8. A method in accordance with claim 1 further comprising receiving measured process parameters from a portable data logger.
