COMPUTER GENERATED TROUBLESHOOTING TREES: APPLICATION AND TRYOUT

摘要

This report describes the results of a project to refine and test a procedure for developing troubleshooting trees by computer. In an earlier project conducted by NASA, a computer program and data preparation procedures were developed. However, the program and procedures were not fully tested. In this project, the procedures and program were refined, adapted, and tested. They were tested by using them to develop troubleshooting trees for a moderately complex electronic system. The troubleshooting trees were then evaluated by inserting faults into the equipment and using the trees to isolate the faults. Although the trees did not lead to isolation of 100% of the faults, the results did indicate that development of troubleshooting trees by computer is feasible. However, further refinements of the process are required before it can be used operationally.
