Abstract

A processor may determine that a first repair order (RO) of an existing cluster of ROs (e.g. corresponding to first and second vehicle symptoms and to first and second corrective actions) refers to a first vehicle related to a set of vehicles. The processor may identify ROs that refer to vehicles from the set and may determine among these identified ROs (i) a first relationship between the first symptom and the first action without the first symptom relating to the second action and/or (ii) a second relationship between the second symptom and the second action without the second symptom relating to the first action. The processor may (i) if the first relationship exists, add the first RO to a first different cluster corresponding to the first relationship and (ii) if the second relationship exists, add the first RO to a second different cluster corresponding to the second relationship.

Claims

1. A method comprising:

based on a first computer-readable vehicle repair order (RO) being associated with an existing cluster identifier that is stored within a non-transitory computer-readable medium to define an existing cluster of ROs, determining, by at least one processor, that the first RO is contained in the existing cluster of ROs, wherein the first RO is one of a plurality of ROs stored within the non-transitory computer-readable medium, wherein the first RO specifies a first vehicle, wherein the non-transitory computer-readable medium has stored thereon vehicle information indicating one or more other vehicles related to the first vehicle, and wherein the existing cluster of ROs is arranged to contain ROs, but only ROs that specify at least first and second vehicle symptoms and a corrective action;

after determining that the first RO is contained in the existing cluster of ROs, the at least one processor identifying, among the plurality of ROs, ROs that do not include symptom-data representative of a relationship between the first and second vehicle symptoms;

based on data stored within the non-transitory computer-readable medium for the identified ROs, making a determination, by the at least one processor, that the first vehicle symptom and the second vehicle symptom are related to the corrective action;

in response to making the determination, the at least one processor maintaining the first RO in the existing cluster of ROs without moving the first RO from the existing cluster of ROs to another cluster of ROs, wherein the existing cluster of ROs contains a first quantity of ROs after the at least one processor maintains the first RO in the existing cluster of ROs;

receiving, by the at least one processor via a vehicle repair tool, a request that comprises at least one search term specifying at least the first and second vehicle symptoms;

making a further determination;

by the at least one processor;

determining a count of ROs, among the identified ROs, that specify the first vehicle symptom and the corrective action; and

determining that the count exceeds a threshold count.

11. The method of claim 9, wherein determining that the second vehicle symptom is also related to the corrective action comprises:

determining that the count exceeds a threshold count.

12. The method of claim 9, wherein determining that the first vehicle symptom is related to the corrective action comprises:

determining that a threshold percentage of the identified ROs specify the first vehicle symptom and the corrective action.

13. The method of claim 9, wherein determining that the second vehicle symptom is also related to the corrective action comprises:

determining that a threshold percentage of the identified ROs specify the second vehicle symptom and the corrective action.

14. A computing system comprising:

a non-transitory computer-readable medium having stored thereon a plurality of computer-readable repair orders (ROs) and vehicle information indicating one or more other vehicles related to a first vehicle; and
