Reliability Analysis of Phased Mission System Based on Micro-replacment Fault Tree

With the extensive application of phased mission system (PMS), the study of phased mission characteristics becomes more and more necessary and urgent. Considering the multi-mode failure of equipment, this paper proposes a reliability modeling and prediction method based on the micro-replacement fault tree, which is used to solve the reliability analysis problem of phased mission system. We take a typical phased mission system as an example to verify the feasibility of the method. This method provides a simpler and more efficient way to evaluate the reliability of complex systems.
