Safety engineering assures that a life-critical system behaves as needed even when pieces(部件) fail. 安全工程是一门应用科学，与系统工程关系密切。安全工程确保生命关键系统即使部件发生故障也能按需要运行。 晋寸称宁尿工诛赶淬贩贯扳捣琼手丢甩碧伊刚竞帽催瓢瞩许饥败杖锐锈晋04第三章(上) IntroductionToSafetyEngineering《安全学原理》(段振伟)课件04第三章(上) IntroductionToSafetyEngineering《安全学原理》(段振伟)课件 3 Introduction to Safety engineering A life-critical system or safety-critical system is a system whose failure or malfunction(故障) may result in death or serious injury. An Example of a Life-Critical System：The picture below illustrates what can happen when a life-critical system fails. This particular crash took place at the Paris Air Show a few years ago. Our understanding is that a mechanical failure caused the crash. The pilot sustained only minor injuries. 生命关键系统或安全关键系统指的是当该系统发生故障时，可能导致死亡或者严重的伤害。一个生命关键系统的例子：下图显示了一个生命关键系统发生故障时能够导致什么事情发生。这次特殊的坠落发生在几年前的巴黎航空表演上。据我们理解是机械故障导致这次坠落。飞行员伤害较小。 汰仅墟乳密饮凤峭松议卫相迸潘兔梧沼慢嫁镜海竭单莲循纺阎纺竭胰副鲍04第三章(上) IntroductionToSafetyEngineering《安全学原理》(段振伟)课件04第三章(上) IntroductionToSafetyEngineering《安全学原理》(段振伟)课件 4 Introduction to Safety engineering Safety engineers distinguish different extents of defective(有缺陷的) operation: A fault is said to occur when some piece of equipment does not operate as designed. A failure only occurs if a human being (other than a repair person) has to cope with the situation. A critical failure endangers one or a few people. A catastrophic“(灾难的) failure endangers, harms or kills a significant number of people. 安全工程师能够区分不同程度的不正常运行状态：故障发生在设备某零件不按设计运转的时候；事故仅发生在工作人员（不是修理工）不得不应付该情况的时候；严重事故能够危及一个或几个人；灾难性的事故危及、伤害或杀死大量的人。 映边举盯齿面赚毗秩荣放衙鲸兽哮癌状销遍头职怀菜砍刁码粕障巨技招巩04第三章(上) IntroductionToSafetyEngineering《安全学原理》(段振伟)课件
