Abstract

A method of augmenting a reliability model for a manufactured product includes receiving a product attribute identifying a product, receiving a first component attribute and a second component attribute, and receiving first manufacturing data and second manufacturing data, the first manufacturing data comprising manufacturing data associated with the first component and the second manufacturing data comprising manufacturing data associated with the second component. The method can include applying a set of compatibility rules to the first manufacturing data and the second manufacturing data, determining pairing data from the application of the set of compatibility rules to the first manufacturing data and the second manufacturing data, obtaining a reliability model of products including the product, augmenting the reliability model based on the pairing data, and performing one or more actions with the augmented reliability model.

Claims (46)

1. A method of augmenting a reliability model for a manufactured product, the method comprising:

receiving a product attribute identifying a product under test, the product under test having been assembled from two or more components, wherein the two or more components include a first component that is installed on the product under test and a second component that is installed on the product under test;

receiving a first component attribute and a second component attribute, the first component attribute identifying the first component and the second component attribute identifying the second component;

receiving first manufacturing data comprising manufacturing data associated with the first component, wherein the first manufacturing data includes data generated during manufacturing of the first component;

receiving second manufacturing data comprising manufacturing data associated with the second component, wherein the second manufacturing data includes data generated during manufacturing of the second component;

comparing the first manufacturing data to the second manufacturing data;

identifying a measure of compatibility between the first component and the second component based on the comparison between the first manufacturing data and the second manufacturing data;

determining pairing data based at least in part on a relationship between a performance of a particular finished product and the measure of compatibility between the first component and the second component, wherein the measure of compatibility represents an effect of pairing the first component with the second component on an expected performance of the particular finished product, and wherein the particular finished product is the product under test or the particular finished product includes the product under test;

retrieving, from a database, the reliability model for a general population of finished products that includes the particular finished product;

storing the reliability model in memory; and

modifying the reliability model stored in memory based on an application of a set of pairing rules to the pairing data to generate an augmented reliability model for use in performing one or more actions to reduce a probability of failure of the product under test under operating conditions.

2. The method of claim 1 , wherein a type of the first manufacturing data and a type of the second manufacturing data is defined by a compatibility model, wherein the compatibility model includes a set of compatibility rules that is configured to determine the pairing data from the set of compatibility rules.

3. The method of claim 1 , further comprising analyzing a multi-dimensional model to reduce a dimensionality of the data when the product under test includes more than the first component and the second component, or when at least one of the first component and the second component of the product under test includes more than one type of manufacturing data.

4. The method of claim 1 , wherein the pairing data indicates that the pairing of the first component and the second component is an unseen pairing.

5. The method of claim 1 , wherein performing one or more actions with the augmented reliability model includes augmenting a maintenance plan for the particular finished product.

6. The method of claim 1 , wherein performing one or more actions with the augmented reliability model includes determining a remaining useful lifetime of the particular finished product based on the augmented reliability model.

7. The method of claim 1 , wherein performing one or more actions with the augmented reliability model includes customizing a data collection method for the particular finished product.

8. The method of claim 1 , wherein the augmented reliability model is a modified reliability model for the particular finished product.

9. The method of claim 1 , wherein obtaining the reliability model comprises querying a manufacturing information database and receiving the reliability model.

10. The method of claim 1 , wherein the particular finished product is in use by an end user.

11. The method of claim 1 , wherein the first and second component attributes and the first and second manufacturing data are received by a compatibility module containing a compatibility model.

12. A computer product comprising a non-transitory computer readable medium storing a plurality of instructions that when executed control a device including one or more processors, the instructions comprising:

receiving a product attribute identifying a product under test, the product under test having been assembled from two or more components, wherein the two or more components include a first component that is installed on the product under test and a second component that is installed on the product under test;

receiving a first component attribute and a second component attribute, the first component attribute identifying the first component and the second component attribute identifying the second component;

receiving first manufacturing data comprising manufacturing data associated with the first component, wherein the first manufacturing data includes data generated during manufacturing of the first component;

receiving second manufacturing data comprising manufacturing data associated with the second component, wherein the second manufacturing data includes data generated during manufacturing of the second component;

comparing the first manufacturing data to the second manufacturing data;

identifying a measure of compatibility between the first component and the second component based on the comparison between the first manufacturing data and the second manufacturing data;

determining pairing data based at least in part on a relationship between a performance of a particular finished product and the measure of compatibility between the first component and the second component, wherein the measure of compatibility represents an effect of pairing the first component with the second component on an expected performance of the particular finished product, and wherein the particular finished product is the product under test or the particular finished product includes the product under test;

retrieving, from a database, a reliability model for a general population of finished products that includes the particular finished product;

storing the reliability model in memory; and

modifying the reliability model stored in memory based on an application of a set of pairing rules to the pairing data to generate an augmented reliability model for use in performing one or more actions to reduce a probability of failure of the product under test.

13. A device comprising:

memory configured to store lines of code; and

one or more processors coupled to the memory, the one or more processors configured to:

receive a product attribute identifying a product under test, the product under test having been assembled from two or more components, wherein the two or more components include a first component that is installed on the product under test and a second component that is installed on the product under test;

receive a first component attribute and a second component attribute, the first component attribute identifying the first component and the second component attribute identifying the second component;

receive first manufacturing data comprises manufacturing data associated with the first component, wherein the first manufacturing data includes data generated during manufacturing of the first component;

receive second manufacturing data comprises manufacturing data associated with the second component, wherein the second manufacturing data includes data generated during manufacturing of the second component;

compare the first manufacturing data to the second manufacturing data;

identify a measure of compatibility between the first component and the second component based on the comparison between the first manufacturing data and the second manufacturing data;

determine pairing data based at least in part on a relationship between a performance of a particular finished product and the measure of compatibility between the first component and the second component, wherein the measure of compatibility represents an effect of pairing the first component with the second component on an expected performance of the particular finished product, wherein the particular finished product is the product under test or the particular finished product includes the product under test;

retrieve, from a database, a reliability model for a general population of finished products that includes the particular finished product;

store the reliability model in memory; and

modify the reliability model stored in memory based on an application of a set of pairing rules to the pairing data to generate an augmented reliability model for use in performing one or more actions to reduce a probability of failure of the product under test.

14. The device of claim 13 , wherein the memory includes a traceability module, compatibility module, and a pairing module.
