Method three of the most widely used approaches , failure mode and effect a nalysis ( fmea ) , fault tree analysis ( fta ) and system hazards analysis ( sha ) were used 方法綜合采用故障模式影響分析方法、故障樹(shù)分析方法和危險(xiǎn)分析方法等安全性分析方法。
Stress - strength interference model of structure reliability is introduced to analyze human reliability . the decrease speed of strength with time is studied by the human stress - strength interference model , and its probability density function is derived . similar to engineering reliability analysis method , ucav system reliability diagram and fault tree are presented , fmeca is also performed 論文的第二部分研究無(wú)人作戰(zhàn)飛機(jī)系統(tǒng)的可靠性分析,在對(duì)人的差錯(cuò)的原因深入分析的基礎(chǔ)上,建立了人的通用差錯(cuò)模型,借鑒結(jié)構(gòu)可靠性分析方法,建立了人的可靠性的應(yīng)力強(qiáng)度模型,推導(dǎo)了強(qiáng)度隨時(shí)間下降速率的概率分布;運(yùn)用工程可靠性分析方法,建立了無(wú)人作戰(zhàn)飛機(jī)系統(tǒng)的可靠性框圖、故障樹(shù),并且做了人的差錯(cuò)的故障模式影響分析。
