METHODS FOR PRODUCING CUSTOMER CONFIGURABLE TECHNICAL MANUALS
First Claim
1. A method to automatically generate 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 failure modes associated with a corrective action from a fault model of the complex system by a processor;
receive in symptoms in real time from sensors monitoring the complex system;
generate a symptom pattern and an associated symptom hash from the received symptoms;
for the symptom pattern, create an ambiguity group of failure modes from the retrieved failure modes;
retrieve repair procedures and test procedures related to the ambiguity group of failure modes from the fault model;
create a troubleshooting tree for the ambiguity group of failure modes by ranking each repair procedure and test procedure;
retrieve technical references encountered while creating the trouble shooting tree; and
compile and render 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.

Abstract
Methods and systems are provided for generating a maintainer troubleshooting tree from the content of a digitally stored fault model of a complex system in real time. The method comprises retrieving all failure modes from a fault model of the complex system for a specific corrective action. The method then receives symptoms from sensors monitoring the complex system in real time and generates a symptom pattern and an associated symptom hash from the received symptoms. The method creates san ambiguity group from the retrieved failure modes. The method further retrieves all repair procedures and test procedures related to the ambiguity group of failure modes, creates a troubleshooting tree for the ambiguity group by ranking each repair procedure and test procedure, and retrieves all technical references encountered while creating the trouble shooting tree. The method then compiles and renders the troubleshooting tree and the references into a user perceivable document.

8. A system for automatically generating a maintainer useable trouble shooting tree from content of a digitally stored fault model of a complex system in real time comprising:
-
a processor; a plurality of sensors configured to monitor the complex system and to supply symptom data in real time to the processor; a memory device containing the digitally stored fault model of the complex system in communication with the processor; and an output device configured to render the maintainer useable trouble shooting tree. - View Dependent Claims (9, 10, 11, 12)

13. A tangible, non-transitory computer readable medium containing instructions that when executed perform the steps of:
-
retrieving all failure modes associated with a corrective action from a fault model of a complex system by a processor; receiving symptoms from sensors monitoring the complex system in real time; generating a symptom pattern and an associated symptom hash from the received symptoms; for the symptom pattern, create an ambiguity group from the failure modes; retrieving all repair procedures and test procedures related to the ambiguity group from the fault model; creating a troubleshooting tree for the ambiguity group by ranking each repair procedure and test procedure; retrieving all technical references encountered while creating the trouble shooting tree; and compiling and rendering 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. - View Dependent Claims (14, 15, 16, 17)
