The weighted structure is used to provide a new method for the system safety analysis 利用加權(quán)結(jié)構(gòu)重要度分析法為系統(tǒng)安全分析提供了新的方法和途徑。
This dissertation focuses on the problems existing in current system safety analysis , especially , modeling and solution of safety system , and integration of methods of safety analysis 本文圍繞當(dāng)前系統(tǒng)安全性分析中存在的系統(tǒng)安全性模型描述與求解,以及安全性分析方法綜合運用等問題進行研究。
While dissertating system safety analysis method , emphasizejd particularly on fta . fta is the method basing on occurred the top matter , analyzing from top to below , processing boolean operation , and in the last find out the mostly reason of faulty . while dissertating system safety appraise , emphasized particularly on dafen method and fuzzy integrated appraise method . dafen method just is used in sub - system and aimed at safety in some environment . fuzzy integrated appraise method process appraise to system safety using the knowledge of fuzzy mathematic which may be a great system or little system . while dissertating s safety decision - making , emphasized particularly on ahp which possess of the relative importance degree basing on experience of expert , constituting judgment matrix . calculating importance degree of every project . processing project - electing and decision - making 在論述系統(tǒng)安全評價時,主要論述了打分法和模糊綜合評價法,打分法針對在某種環(huán)境下的安全性,進行子系統(tǒng)安全評價。模糊綜合評價是運用模糊數(shù)學(xué)的知識進行系統(tǒng)安全評價,所評價的系統(tǒng)可以是一個大系統(tǒng),也可以是一個小系統(tǒng)。在論述安全決策時,主要論述了層次分析法,層次分析法主要是根據(jù)專家經(jīng)驗,給出各因素的相對重要度組成判斷矩陣,計算各方案措施的相對重要度,進行方案優(yōu)選,進行決策。
Constructing condition of tunnel engineering is very complicated , and the variable factor is much more , and the past experiencing safety management are not adapted to requirement of modern management , so the modern science management method - system safety engineering - come into being . this thesis dissertate it from the concept of system safety engineering , emphasized particularly on system safety analysis , system safety appraise and safety decision - making 隧洞工程的施工條件是非常復(fù)雜的,并且存在的不穩(wěn)定因素比較多,安全隱患很大。傳統(tǒng)的經(jīng)驗型安全管理已不能適應(yīng)現(xiàn)代化管理的需要,所以產(chǎn)生了現(xiàn)代化的科學(xué)管理方法? ?安全系統(tǒng)工程。本文從介紹安全系統(tǒng)工程的概念入手,側(cè)重論述了系統(tǒng)安全分析、系統(tǒng)安全評價和安全決策。
