摘要：

Insufficient bottom reliability data accumulation of some functional modules of the domestic Head Up Dis⁃ play（HUD）system poses difficulty in reliability analysis support. To solve this problem，a reliability analysis method for multi-phased mission of the HUD system based on the Intuitionistic Fuzzy Bayesian Network（IFBN）is proposed. The modeling method for multi-Phased Mission System（PMS）based on the Bayesian network is first studied，and meanwhile the possible Commom Cause Failure（CCF）effects are comprehensively considered. The fuzzy event fail⁃ ure data evaluation method based on the intuitionistic fuzzy theory is then explored，the fuzzy interval division method suitable for avionics equipment and the conversion algorithm between the intuitionistic fuzzy number and failure data proposed，and the intuitionistic fuzzy number aggregation algorithm based on the Tω operator adopted to reduce fuzzy accumulation. Finally，the multi-phased mission reliability is calculated with a HUD system as an example. The pro⁃ posed method provides support for reliability analysis under the condition of fuzzy bottom failure data. © 2023 AAAS Press of Chinese Society of Aeronautics and Astronautics.
