Radiological decision aiding using multiattribute analysis techniques

Multiattribute analysis techniques for aiding complex decision making and their use in the optimization of radiological protection problems is briefly discussed. The analysis begins with the identification of the set of options or available solutions to the problem. Options are compared by evaluating their performance with reference to a number of factors or attributes which are relevant to the decision. In order that options may be compared, scores are assessed in terms of how valued each score is to the decision maker. Changes in preference along a particular scale, or value functions, vary between individuals or preference groups. Weighting the values associated with each attribute then leads to the preferred option. (UK)
