Claim:
A method of identifying fault conditions for complex systems based on historical non-coded data, the method including the steps of: grouping the historical non-coded data into a plurality of observations and a plurality of repairs; assigning a Standard Repair of a plurality of Standard Repairs to each of said plurality of repairs and a Standard Observation of Standard Observations to each of said plurality of observations, said plurality of Standard Observations including a description of each of said plurality of Standard Observations and said plurality of Standard Repairs including a description of each of said plurality of Standard Repairs, said description of each of said plurality of Standard Observations and said description of each of said plurality of Standard Repairs comprising a phrase, said step of assigning a Standard Repair of a plurality of Standard Repairs to each of said plurality of repairs and a Standard Observation of a plurality of Standard Observations to each of said plurality of observations comprising assigning one or more weights to each of said descriptions of said plurality of Standard Observations and each of said descriptions of said plurality of Standard Repairs and resolving the historical non-coded data into one of said plurality of Standard Observations and said plurality of said Standard Repairs, each of said one or more weights indicating a phrase importance and corresponding to a relative importance in said resolving said historical data into one of said plurality of Standard Observations and said plurality of said Standard Repairs; analyzing said plurality of repairs to determine associated observation signatures, each of said observation signatures based on one or more of said plurality of observations; assigning a fault code to each observation signature, said fault code identifying a fault condition; and communicating the fault code to a user interface.
