Ranking the Vulnerable Components of Aircraft by Considering Performance Degradations

One of the most important tasks of aircraft vulnerability assessment is to rank vulnerable components so that proper actions can be applied to the weaker components to improve survivability. Currently, when comparing the contributions of components to the overall aircraft vulnerability in a military context, existing methods focused on the aircraft kill state without considering the intermediate states that are related to performance degradations. This work aims to investigate how performance-related importance measures in the field of reliability can be modified to rank the vulnerable components. Component vulnerability importance measures considering performance degradations are proposed. Two applications, one with eight critical components and one consisting of 84 noncritical components and 28 critical components dealing with aircraft being hit by metallic fragments detonated from a missile, are provided. The analysis shows that the proposed method is useful for engineers to determine which components ...
