The theory of minimum cut sets and its application in accident analysis are described with emphasis on putting forward the importance analysis of the weighted structure in sequence gradation of the bottom events of the fault tree 闡述最小割集理論及其在事故分析中的作用,著重提出了對(duì)故障樹底部事件進(jìn)行排序分級(jí)的加權(quán)結(jié)構(gòu)重要度分析法。
Abstract : the complexity of tree set analysis for network was compared with that of minimum cut set analysis . if was illustrated by an example that the analysis method based on minimum cut set is the best approach for the availability analysis of network 摘要:對(duì)網(wǎng)絡(luò)分析的樹集分析法與最小割集分析法的復(fù)雜性進(jìn)行了比較,并示例說(shuō)明以最小割集為基礎(chǔ)進(jìn)行網(wǎng)絡(luò)可用性分析是最佳的技術(shù)途徑。
The minimum cut set of the fault tree was obtained , the major dangerous factors in the explosion elimination processing of lpg tanks were realized , and the corresponding prevention measures to ensure the safety of the explosion elimination processing were suggested 通過(guò)對(duì)液化石油氣儲(chǔ)罐銷爆處理過(guò)程中潛在危險(xiǎn)因素的系統(tǒng)分析,得到了事故樹的各階最小割集,確定了液化石油氣儲(chǔ)罐銷爆過(guò)程中的主要危險(xiǎn)源,提出了相應(yīng)的安全預(yù)防措施,保證了該化工廠液化石油氣儲(chǔ)罐銷爆過(guò)程中的安全。
