以铁路自动售票系统应用服务为例,应用软件故障树分析法进行分析。根据铁路自动售票系统应用服务的特点,建立该系统应用服务的失效模型,采用最小割集分析法,确定影响系统应用服务失效的主要因素,从而在以后的设计过程中采取有效措施防止错误或故障的发生,达到提高铁路自动售票系统应用服务稳定性的目的。
Taking railway automatic ticketing system application service as an example, the software fault tree analysis method is used to analyze. According to the characteristics of the application service of the automatic ticket vending system, the failure model of the application service of the system is established. The minimum cut set analysis method is used to determine the main factors that affect the failure of the system application service so as to take effective measures to prevent errors or faults in the future design process The purpose of improving the stability of the application services of the automatic ticket system of the railway.
