ic vs. Deterministic Introduction of Safety Review ? page 9 ? March, 2022 風(fēng)險(xiǎn) =可能性 x 結(jié)果的影響 Risk = Probability x Effect 可能性是統(tǒng)計(jì)學(xué)的部分 Probability is the STATISTICAL part 結(jié)果的影響是確定性的部分 Effect is the DETERMINISTIC part 例如: For example: 1) 某人假如碰巧踩到香蕉皮滑倒,風(fēng)險(xiǎn)是什么? What is the risk a person runs into in case she/he slips a banana peel 2) 對(duì)于地球上一個(gè)人來(lái)說(shuō),一旦宇宙另外的星系發(fā)生核爆炸,風(fēng)險(xiǎn)是什么? What is the risk for a person in our pla in case of a nuclear explosion in another galaxy of the universe 什么是風(fēng)險(xiǎn)? What is Risk? Introduction of Safety Review ? page 10 ? March, 2022 可能性 Probability ? 根據(jù)不同的模型計(jì)算(預(yù)先危險(xiǎn)性分析,故障模型和失效影響分析,故障樹分析 …… ) Calculated according to different methods (HAZOP, FMEA, Fault Tree Analysis…) ? 建議從做簡(jiǎn)單的開始(通常是 FMEA),然后如果需要,使用最精確的方法(故障樹分析)。 It is suggested to start from the easiest (usually FMEA) then, if needed, use the most precise (Fault Tree Analysis) ? 最精確的方法也是成本最高的方法(需要時(shí)間和費(fèi)用)。所以建議僅使用該方法用于評(píng)估非常復(fù)雜和危險(xiǎn)的工藝。 The most precise is also the most expensive (time and experts needed) so its use suggested only to evaluate the probability of very plicated and dangerous processes.
