DECISION CRITERIA TO SELECT A SUITABLE CRITICALITY ASSESSMENT TECHNIQUE

Abstract

The occurrence of events associated to failures in any industrial plant may lead to some increases in overall cost (direct or indirect cost) in the production process. In order to assess and rank events associated with failures, those criteria of importance will depend on the organization and its context. The most used criteria are: Safety, Environment, Production, Costs, Failure Frequency and Mean Time To Repair. Therefore, it is necessary to identify those processes, areas, equipment and components that generate a higher impact on the occurrence of failure or, in other words, those which are potentially critical, where their impact refers to the degree in which the occurrence of the failure may affect the process continuity.
