摘要：
As a high availability product, Electronic Flight Instrument System (EFIS) has very complicated redundancy structures to fulfill high safety integrity requirement. This paper presents a comprehensive study on the availability analysis for EFIS by using Dynamic Fault Tree (DFT) approach based on Markov chain with modularization method. The static fault sub tree is solved by Binary Decision Diagram (BDD) and the dynamic fault sub-tree is solved by Markov chain. A novel Markov chain expression is utilized to avoid state explosion of dynamic fault sub-tree. Besides, Minimal Cut Sequence Set (MCSS) are generated. At last, Monte Carlo simulation is carried out to verify the theoretical results.
