摘要

空中交通管制(ATC)系统是最具特点的分布式系统之一。由于它与乘客的生活关系密切，对网络和软件应用都有很高的可靠性要求。本文采用马尔可夫过程对空管系统的软件可靠性进行分析。首先，根据维护策略得到状态转换图;然后，通过对故障率、维修率等关键参数的调优，对空管系统的软件可靠性进行了定量仿真。并对系统冗余和部件冗余的可靠性进行了比较。对这些仿真结果的分析将对提高空管软件的可靠性起到指导作用。

Software reliability analysis in air traffic control system

Air Traffic Control (ATC) system is one of the most characteristic distributed systems. It requires high reliabilities of both network and software application due to its close relationship with passengers' life. In this paper, the Markov process is adopted to analyze the software reliability of ATC system. Firstly, the state transition diagram is obtained according to the maintenance strategy. Then, by tuning some key parameters such as failure ratio and maintenance ratio, the software reliability of the ATC system is simulated quantitatively. Furthermore, a reliability comparison of system redundancy and component redundancy is presented. The analysis about these simulation results will give us a guidance to improve the software reliability of ATC.
