[Abstract]:Civil Aviation passenger Service Information system (TPIS(Travelsky Passenger Information and Service System) is the core system of the State and Civil Aviation Administration (CAA), which includes 21 subsystems with huge functions and complex structure. The research on the reliability of TPIS system plays an important role in the field of civil aviation transportation. The main work of this paper is as follows: in the aspect of module reliability parameter, aiming at the source of components of TPIS subsystem, the performance and function are different. The paper is based on DTMC model and integrates Black Box model into White Box concept. In this paper, the method of module reliability competition matching selection is proposed to replace the single fitting algorithm. The Bayes estimation is combined into the NHPP model and the Goel-Okumoto model respectively, and the statistical characteristics of the failure data are fully grasped by the prior information. The reliability parameters of each module are closer to the true value, and the final evaluation results are more reliable. In the aspect of module interaction mode, aiming at the limitation of the assumption that module failure is independent and module migration conforms to random Markov, considering the complex structure of each subsystem of TPIS and the diversity of interaction modes among modules, In this paper, a modular action model method is proposed, and the special module action mode in TPIS system is classified and analyzed, and the conversion process of each special module action mode to the model hypothesis is analyzed one by one. It makes up for the difference between the original model and the real TPIS system. Finally, the key modules of TPIS system reliability evaluation and key parameter analysis, especially the key parameter analysis, are listed, which have great impact on the system reliability and the key modules with high failure risk at present. Thus, the feasibility technical reference can be provided to improve the reliability of the system.
