【摘要】：為保障鐵路危險貨物專用線安全運(yùn)行,利用基于粗糙集-突變理論的風(fēng)險評價方法對鐵路危險貨物專用線進(jìn)行風(fēng)險分析。在構(gòu)建系統(tǒng)的評價指標(biāo)體系基礎(chǔ)上,利用粗糙集方法計算指標(biāo)權(quán)重,再用突變評價法逐級計算,得到系統(tǒng)最終突變值,以突變值反映系統(tǒng)風(fēng)險的相對高低�；诒本╄F路局管內(nèi)10條危險貨物專用線綜合分析報告內(nèi)容,利用該評價方法對這10條專用線進(jìn)行風(fēng)險評價。實例分析表明,綜合分析報告所描述的問題較多的專用線,其突變值也較低,風(fēng)險相對較高,評價結(jié)果基本符合實際情況。
[Abstract]:In order to ensure the safe operation of the railway dangerous goods private line, the risk evaluation method based on rough set and catastrophe theory is used to analyze the risk of the railway dangerous goods private line. On the basis of constructing the evaluation index system of the system, the index weight is calculated by rough set method, and then calculated step by the catastrophe evaluation method, and the final catastrophe value of the system is obtained, which reflects the relative level of the system risk. Based on the comprehensive analysis report of 10 dangerous goods special lines in Beijing Railway Administration, the risk assessment of these 10 special lines is carried out by using the evaluation method. The analysis of examples shows that the special line with more problems described in the comprehensive analysis report has lower mutation value and higher risk, and the evaluation results are basically in line with the actual situation.
