ABSTRACT
Resilience is essentially linked to a dynamic view of risk control. This chapter looks critically at the ARAMIS risk assessment approach designed for evaluating high-hazard chemical plants, which contains a management audit. The ARAMIS models and the auditing techniques developed have a strong emphasis on functional process analysis. The IRMA audit and its close relation, the ARAMIS risk assessment method, have been developed during studies in which the group in Delft has participated, in collaboration with a number of others. The technical modelling of the plant identifies all critical equipment and accident scenarios for the plant concerned and analyses what barriers the company claims to use to control these scenarios. It is essential that this identification process is exhaustive for all potential accidents with major consequences otherwise crucial scenarios may be missed, which may later turn out to be significant.
