Abstract

A system, computer-readable medium, and method for updating a decisioning algorithm are provided. In the method, operational parameter data from a first device is evaluated using a decisioning algorithm to determine if an alert should be sent. The alert indicates a possible performance issue associated with a component of the first device. The operational parameter data includes a value of an operating characteristic of the first device. When a determination is made to send the alert, an alert message including a first indicator indicating the possible performance issue of the component of the first device is created. The alert message is sent to a second device. The decisioning algorithm is updated based on a second indicator received from a third device. The second indicator indicates either that the alert was useful or that the alert was not useful.

Claims

1. A system comprising a monitoring device, the monitoring device comprising:

a processor; and

a computer-readable medium operably coupled to the processor, the computer-readable medium having computer-readable instructions stored thereon that, when executed by the processor, cause the monitoring device to

evaluate operational parameter data, received from a first device, using a decisioning algorithm to determine if an alert should be sent, wherein the alert indicates a possible performance issue associated with a component of the first device, and further wherein the operational parameter data comprises a value of an operating characteristic of the first device; and

when a determination is made to send the alert,

create an alert message, wherein the alert message includes a first indicator indicating the possible performance issue of the component of the first device;

send the alert message to a second device; and

update the decisioning algorithm based on a second indicator received from a third device, wherein the second indicator indicates either that the alert was useful or that the alert was not useful.

2. The system of claim 1, wherein the value of the operating characteristic of the first device is determined using a sensor mounted to measure the value at the first device.

3. The system of claim 1, wherein the operating characteristic includes a parameter of a second component of the first device that is different than the component of the first device.

4. The system of claim 1, further comprising processing the operational parameter data to form decision data before evaluating the operational parameter data, wherein the evaluating step is performed using the decision data, and the decision data is calculated from the operational parameter data.

5. The system of claim 1, wherein the second device is the same device as the third device.

6. The system of claim 5, further comprising the second device which comprises:

a display;

a second processor;

a communication interface configured to receive the alert message; and

a second computer-readable medium operably coupled to the second processor, the second computer-readable medium having second computer-readable instructions stored thereon that, when executed by the second processor, cause the second device to

control presentation of a user interface window in the display, wherein the user interface window includes a first selector and a second selector, wherein selection of the first selector indicates that the alert was useful and selection of the second selector indicates that the alert was not useful;

receive a third indicator indicating selection of either the first selector or the second selector;

define the second indicator based on the received third indicator;

create the alert response message including the defined second indicator; and

send the alert response message to the monitoring device.

7. The system of claim 6, further comprising the first device which comprises:

a sensor mounted to measure the value;

a third processor; and

a third computer-readable medium operably coupled to the third processor, the third computer-readable medium having third computer-readable instructions stored thereon that, when executed by the third processor, cause the first device to

receive the value from the sensor; and

send the value to the monitoring device.

8. The system of claim 1, further comprising the first device which comprises:

a sensor mounted to measure the value;

a second processor; and

a second computer-readable medium operably coupled to the second processor, the second computer-readable medium having second computer-readable instructions stored thereon that, when executed by the second processor, cause the first device to

receive the value from the sensor; and

send the value to the monitoring device.

9. The system of claim 8, wherein the first device is the same device as the third device.

10. The system of claim 9, wherein the first device further comprises:

a display; and

the second computer-readable instructions further cause the first device to

control presentation of a user interface window in the display, wherein the user interface window includes a first selector and a second selector, wherein selection of the first selector indicates that the alert was useful and selection of the second selector indicates that the alert was not useful;

receive a third indicator indicting selection of either the first selector or the second selector;

define the second indicator based on the received third indicator;

create the alert response message including the defined second indicator; and

send the alert response message to the monitoring device.

11. The system of claim 1, wherein evaluating the operational parameter data results in determining that a second alert should be sent.

12. The system of claim 11, wherein the second alert is sent in a separate alert message.

13. The system of claim 11, wherein the second alert is included in the alert message.

14. The system of claim 11, wherein a second alert response message is received in response to the second alert.

15.
