【正文】 目的是計算影響有多大。Usually we can use deterministic approach to evaluate what can be wrong with an activity or a process or… . 有時這些過程 : Sometimes the processes are: ?用確定性的方法來處理太復(fù)雜 Too plicated to be treated with deterministic methods ?使用確定性的方法費用太高 The deterministic method is too expensive to be used ?確定性的方法需要太長時間 The deterministic method requires too long time 所以我們需要分解問題，引入另外的方法：概率性的 /統(tǒng)計學(xué)方法 So we have to break down the problem and introduce an additional approach: probabilistic/statistical。 To make an equipment safer we should addon other equipment to control and warn in advance in case of danger. 控制措施越多，設(shè)備越安全。 The effects can, at first, be predicted according to the mon experience, . people falling down。 It is suggested to evaluate “domino effects”, . the effect under examination may led to a small fire. But if it happens beside a big tank, the effect can evolve to a very big one. Introduction of Safety Review ? page 12 ?
