Claim One:
1. A method for automatically generating a maintainer useable troubleshooting tree from content of a digitally stored fault model of a complex system in real time, the method comprising: for a specific corrective action, retrieve, by a processor, failure modes associated with the corrective action from a fault model of the complex system; receive, by a processor, symptoms in real time from sensors monitoring the complex system; generate, by a processor, a symptom pattern and an associated symptom hash from the received symptoms; for the symptom pattern, create, by a processor, an ambiguity group of failure modes from the retrieved failure modes; retrieve, by a processor, repair procedures and test procedures related to the ambiguity group of failure modes from the fault model; create, by a processor, a troubleshooting tree for the ambiguity group of failure modes by ranking each repair procedure and test procedure; retrieve, by a processor, technical references encountered while creating the trouble shooting tree; and compile and render, by a processor, the troubleshooting tree and the references into a user perceivable document based on a standard technical manual skeleton data structure configured to record the trouble shooting tree and the references, wherein when a first hash value and a first symptom pattern of a first failure mode are both identical to a second symptom pattern and a second hash value of a second failure mode, the method further comprises changing a delimiting character of one of the first and second symptom patterns.
