| Abstract: | Generalized stochastic Petri nets(GSPN) is adopted to develop the reliability model of dissimilar redundant flight control computers of Boeing 777. By using Petri nets, static architectures and dynamic behaviors of the system are properly described. To solve the problem that the model was too complex to use the existing algorithm, a hierarchical method which divides the entire system into branch-level, passage-level and system-level, is proposed. Then GSPN model is converted to Markov chain to calculate the... |
