FUSION OF STRUCTURAL AND CROSS-FUNCTIONAL DEPENDENCIES FOR ROOT CAUSE ANALYSIS
First Claim
1. A method of enhancing service diagnostics for root cause analysis of an identified problem in a vehicle by generating a functional taxonomy database that is utilized in cooperation with a structural taxonomy database, the structural taxonomy database identifying structural relationships between parts of a vehicle, and the functional taxonomy database identifying functional relationships between parts of the vehicle, the method comprising the steps of:
- obtaining service repair data of previously serviced vehicles from a memory storage device, the service data identifying parts serviced on the vehicle during a respective service repair;
compiling the service data based on a service repair history for each vehicle;
identifying each vehicle within the compiled service data having at least two service repairs performed within a predetermined period of time;
identifying combinations of parts serviced for each vehicle;
determining a count indicating the number of times each combination appears in the compiled service data for the identified vehicles having at least two service repairs;
identifying the combinations having counts greater than a predetermined threshold;
determining whether any of the combinations having counts greater than the predetermined threshold are present in the structural taxonomy database;
selecting only the combinations that are not present in the structural taxonomy database and have counts greater than the predetermined threshold; and
updating a functional taxonomy database by assigning the selected combinations to the function taxonomy database, wherein the functional taxonomy database and the structural taxonomy database are made available to a service technician via a computer to assist the service technician in diagnosing the root cause.

Abstract
A method is provided for enhancing service diagnostics for root cause analysis of an identified problem in a vehicle. Service repair data of previously serviced vehicles is obtained from a memory storage device. The service data is compiled based on a service repair history for each vehicle. Each vehicle within the compiled service data having at least two service repairs performed within a predetermined period of time is identified. Combinations of parts serviced during each service repair are identified. A count is determined that indicates the number of times each combination appears in the compiled service data. The combinations having counts greater than a predetermined threshold are identified. A determination is made whether any of the combinations having counts greater than the predetermined threshold are present in the structural taxonomy database. A functional taxonomy database is updated by assigning the selected combinations to the function taxonomy database not present in the structural taxonomy database.
