Abstract
The Challenger space shuttle disaster was due to failure of a solid rocket booster field joint. The NASA management and engineering team’s failed in utilizing Failure Mode & Effect Analysis (FMEA) in proper identification and communication of critical system failure modes and their effects. The benefits of fuzzy logic and its application to FMEA methodology could have made a major difference in the outcome as it would have provided more granularities to the risk priority rating. This study reports a platform for performing FMEA that utilizes a conflict resolution module in order to dilute the conflict in risk priority ratings. The platform has been applied to a real case to demonstrated the its application.
