Abstract

A method includes receiving, by an inventory management system (IMS) program executing on a computing device, a remaining useful life (RUL) formulation for a part of a machine that estimates an amount of time for which the part will continue to perform its intended function and a potential unscheduled maintenance event. The method also includes receiving, by the IMS program, replacement part order lead time data and anticipated replacement part inventory level data from a part inventory database. The method also includes determining, by the IMS program and based on the RUL formulation, the replacement part order lead time data, and the anticipated part replacement inventory level data, that an order for a replacement part should be initiated.

Claims

1. A method comprising:

receiving, by an inventory management system (IMS) program executing on a computing device, a remaining useful life (RUL) formulation for a part of a machine that estimates an amount of time for which the part will continue to perform its intended function and a potential unscheduled maintenance event;

receiving, by the IMS program, replacement part order lead time data and anticipated replacement part inventory level data from a part inventory database; and

determining, by the IMS program and based on the RUL formulation, the replacement part order lead time data, and the anticipated part replacement inventory level data, that an order for a replacement part should be initiated.

2. The method of claim 1, further comprising:

generating an output, by the IMS program, indicating that the order for the replacement part should be initiated.

3. The method of claim 1, further comprising:

receiving, by the IMS program executing on the computing device, scheduled maintenance events data from a maintenance database; and

comparing, by the IMS program executing on the computer device, the potential unscheduled maintenance event with the scheduled maintenance events data.

4. The method of claim 1, further comprising:

displaying, by the IMS program executing on the computing device, replacement part order, shipping, and backorder status information.

5. The method of claim 1, wherein the RUL formulation is a function of at least one of the following:

material and structural properties data of the part;

forecasted loading usage estimations of the part; and

historical degradation data of the part.

6. The method of claim 5, wherein the material and structural properties data of the part includes at least one of geometry data of the part, material data of the part, design loads of the part, mechanics of materials of the part, structural analysis of the part, environmental factors, and experimental data of the part.

7. The method of claim 5, wherein the forecasted loading usage estimations of the part includes estimations of length of time of future usage of the part, environmental conditions of future usage of the part, and load amounts of future usage of the part.

8. The method of claim 5, wherein the historical degradation data of the part includes at least one of physical phenomena data of the part gathered by at least one sensor disposed proximate the part, and observable phenomena data of the part gathered at least in part via manual inspection of the part.

9. The method of claim 5, wherein the RUL formulation is a function of load usage report data detailing a use of the part over time.

10. The method of claim 1, further comprising:

receiving, by the IMS, the RUL formulation for the part of the machine from a remaining useful life (RUL) formulation module;

receiving, by the RUL formulation module, material and structural properties data of the part;

receiving, by the RUL formulation module, forecasted loading usage estimations of the part;

receiving, by the RUL formulation module, historical degradation data of the part; and

determining, by the RUL formulation module, the RUL formulation based upon an analysis of the material and structural properties data of the part, the forecasted loading usage estimations of the part, and the historical degradation data of the part.

11. A system comprising:

a computing device comprising at least one processor; and

an inventory management system (IMS) program executable by the at least one processor of the computing device and configured to;

receive a remaining useful life (RUL) formulation for a part of a machine that estimates an amount of time for which the part will continue to perform its intended function and a potential unscheduled maintenance event;

receive replacement part order lead time data and anticipated replacement part inventory level data from a part inventory database; and

determine, based on the RUL formulation, the replacement part order lead time data, and the anticipated part replacement inventory level data, whether and when a user should order a replacement part.

12. The system of claim 11, wherein the IMS program is further configured to:

compare the RUL formulation for the part of the machine to a RUL formulation of a second part of same design of a second machine; and

determine, based on the RUL formulation of the part, the RUL formulation of the second part, and the anticipated part replacement inventory level data, a probability of potential shortage of the replacement part.

13. The system of claim 12, wherein the RUL formulation of the part is a function of at least one of the following:

material and structural properties data of the part;

forecasted loading usage estimations of the part; and

historical degradation data of the part.

14. The system of claim 13, wherein the RUL formulation of the second part is a function of at least one of the following:

material and structural properties data of the second part;

forecasted loading usage estimations of the second part; and

historical degradation data of the second part,

wherein the material and structural properties data of the second part is substantially the same as the material and structural properties data of the part.

15. The system of claim 14, wherein the IMS program is further configured to:

receive an input and adjust the forecasted loading usage estimations of the part based on the input to modify a timing of the potential unscheduled maintenance event.
