The Design of Mathematics Model on Double System Navigation Equipment Reliability

研究和分析双机制设计体制的可靠性结构模型,进而推导和建立双机制导航设备的可靠性数学模型是十分必要的。针对国内外地面导航设备采用双机制设计体制,利用全概率公式和泊松分布分析并推导出双机制设计的整机系统可靠性模型,给出了系统的可靠度(R)和平均故障间隔时间(MTBF)的主要表达式。

Analyze and conclude reliability model of designing double system to drive and build the mathematics model on the double system navigation equipment reliability is necessary.For the navigation of domestic and overseas use the double system,the paper utilized the Complete Probability Formula and Poisson distribution to analyze.Then we deduce a whole sysyem reliablity model about the double system design.And the reliabilty（R）and the MTBF of the system is given in this paper.
