轨道交通综合监控系统RAM分析计算方法研究

可靠性、可用性和可维修性(RAM)分析是衡量1个系统是否稳定可靠的主要方法,利用RAM分析可及时了解系统的状态,促使保障措施的引入,引导系统持续改进。在目前国内城市轨道交通综合监控系统(ISCS)建设及运营过程中,一般要求对ISCS系统的RAM进行全面控制及定量分析。面向城市轨道交通ISCS系统,研究了适用于对ISCS系统进行RAM定量分析的可靠性数学模型,提出一种基于该可靠性模型的RAM定量分析计算方法,并通过相关算例证明了该方法的实用性。

Analysis and calculation method of RAM for integrated supervisory and control system of rail transit

Reliability,availability and maintainability（RAM）is a main measure of the stability and reliability of a system,which keeps grasping the system state,prompting the introduction of safeguard measures,and guiding the continuous improvement of the system.The full control and quantitative analysis of RAM are general required in the building and operation process of the integrated supervisory and control system（ISCS）of domestic rail transit.Therefore,this paper studies the RAM mathematical model,and proposes a RAM quantitative calculation method based on the reliability model.In addition,an example is given to prove the usefulness of the method.
