7. Comparative studies of expert judgement criticality methods

In the absence of formalized feedback, collective expert judgment is the only possible way of determining criticality, using one of the above methods. The grid in table 5 gives the most useful characteristics for choosing a method for determining equipment criticality. Analysis of this grid shows that the brainstorming method performs less well. This can be explained by the fact that this method relies on superficial knowledge, in the sense of artificial intelligence expert systems [H 1 990] , and does not use an iterative method of consulting experts.
