Ahp/Anp-Based Risk Assessment Customisation

Abstract

Complex conditions of surrounding environment and a lack of reliable information about it make contemporary decisions prone to risk very much. This is why a reliable risk assessment becomes even more important today. Imperfect nature of available information means that risks can be often expressed in qualitative measures, only. Inherent merits make AHP/ANP technique appropriate for risk assessment in such the case, therefore. Note, however, that adequate risk assessment depends on the ability to address risk attitude. The attitude may deal with both risk neutrality, risk apprehension, and tendency towards risk taking. The common application of the technique for risk assessment is nevertheless based on the use of Saaty's linear judgement scale that is rather adequate of coping with a casual neutralattitude to risk, only. The development of the technique provided nevertheless alternative non-linear judgement scales. This is why their applicability for a reliable risk assessment while taking into account alternativenon-neutralrisk attitudes is discussed in the paper. Two scales which provide necessary means with this regard are finally recommended in the paper.
