Abstract

This paper presents a new failure analysis method, Failure Identification for Mission Analysis (FIMA), which performs an overall and mission-specific failure analysis for complex systems. The FIMA method identifies all possible functions of a complex system and then analyzes how various failures may have differing effects on these functions. Then, the FIMA method uniquely uses this information to analyze specific mission plans, which are made up of individual mission tasks that a system must complete. The FIMA method uses multiple unique metrics to determine the effects of a given failure scenario on a potential mission plan and then uses other unique metrics to assess and optimize a new mission plan based on the system's remaining tasks and functionality. This method aims to utilize failure information to enhance the adaptability of complex systems in order to reduce the effects of failures and extend lifespans.
