摘要
为了实施新的安全设计技术,需要很多对风险的定量和可靠性评估方法。传统流程危险分析方法集中于危险的识别,使用对风险评估定性的方法。最近颁布的国际标准IEC 61508,提供了流程危险分析和风险评估的一种新方法。
In order to implement these newer design techniques, more quantitative methods of risk and reliability assessment are required. Traditional process hazard analysis methods focus on hazard identification with a qualitative approach to risk assessment. A recently released international standard, IEC 61508, provides a new method of process hazard analysis and risk assessment.
