Decisions and decision support for major accident prevention in the process industries

摘要

Decision making is a central component in the management of safety-critical operations. Some attempts have been made to employ Quantitative Risk Analysis as input to such decisions. Although adequate for long-term planning where the average risk is the relevant parameter, such systems tend to fall short in operational and instantaneous decisions where 'average risk' is of less relevance. In this paper we investigate how operational and instantaneous risk can be managed and supported.
