Abstract

In view of the limitation that Fault tree analysis ignores many factors that have an impact on reliability allocation, making the allocation result unreasonable and unable to obtain the optimal allocation result, a fault analytic hierarchy process based on analytic hierarchy process (AHP) is proposed, Combine the subjective evaluation of experts with the objective calculation results of fault trees. This method is applied to various devices and systems, allowing for a deep understanding of the main factors affecting the system and their degree of correlation, thereby effectively completing maintenance work, improving equipment reliability, and providing important basis for product design and production processes.

Keywords

Analytic hierarchy process, fault tree analysis, reliability.
