【摘要】：為了對核安全級儀控系統(tǒng)軟件可靠性進(jìn)行定量評估,研究依照貝葉斯網(wǎng)絡(luò)建模步驟進(jìn)行模型建設(shè)的方法。對國際上幾種主要核安全級儀控系統(tǒng)標(biāo)準(zhǔn)體系進(jìn)行對比分析,構(gòu)建核安全級系統(tǒng)軟件可靠性評估綜合模型和子模型,使用貝葉斯公式對模型可靠性進(jìn)行量化計(jì)算和評估,提出通過衡量模型各節(jié)點(diǎn)的敏感度驗(yàn)證模型建立的合理性。實(shí)現(xiàn)運(yùn)用貝葉斯網(wǎng)絡(luò)方法,通過對系統(tǒng)因素關(guān)系分析,結(jié)合專家定性判斷,對復(fù)雜系統(tǒng)進(jìn)行模型構(gòu)建,同時(shí)提供對系統(tǒng)內(nèi)不確定因素進(jìn)行定性與定量相結(jié)合的預(yù)測和驗(yàn)證的方法。
[Abstract]:In order to quantitatively evaluate the software reliability of the nuclear safety level meter and control system, the modeling method based on Bayesian network is studied. This paper makes a comparative analysis of several international standard systems of nuclear safety meter and control system, constructs a comprehensive model and sub-model for software reliability evaluation of nuclear safety grade system, and calculates and evaluates the reliability of the model quantitatively by using Bayesian formula. The rationality of the model is verified by measuring the sensitivity of each node in the model. By using Bayesian network method, by analyzing the relationship between system factors and experts' qualitative judgment, the model of complex system is constructed. At the same time, the method of qualitative and quantitative prediction and verification of uncertainty in the system is provided.
