空管监视信息处理软件可靠性分析

Reliability Analysis of Surveillance Information Processing Software in ATC

在空管监视信息处理软件功能架构的基础上,文章首先对各模块进行定性分析,然后对各模块的开发难度、开发水平和调用程度进行量化,最后预测各模块的故障概率;依据故障概率数据,简化模块之间的依赖关系,基于经典模型进行可靠性分配计算,定位潜在安全隐患和薄弱环节,进而通过故障模式分析,采取有针对性的措施,以提高软件可靠性。

On the basic of function infrastructure of surveillance information processing software in ATC,the paper first analyzes qualitatively of each module,and qualify its difficulty of development,level of development,degree of invocation,and lastly forecast failure probability of each module.According to the result,relationship among each module is simplified,reliability allocation is transformed to adopt classical one kind and calculate numerical value of allocation.Once the potential hidden danger and weak link are located,failure model and effect analysis are followed to use,a lot of measures are adopted,so the reliability of the software is improved.
