A consensus approach for synthesizing the elements of comparison matrix inthe Analytic Hierarchy Process

The Analytic Hierarchy Process (AHP) has been widely utilized to solve mult icriteria decision-making problems in synthesizing conflict opinions. Norma lly, AHP uses the geometric averaging approach to synthesize preference wei ghts determined by decision-makers. This approach has been criticized by ma ny researches since synthesis weight may not reach a consensus. To make the synthesis acceptable to all decision-makers, the study proposes a computer -aided approach to achieve a compromise for all the elements in the compari son matrix while implementing AHP. Accordingly, decision-makers can conveni ently exchange trustful information, which is generated by the embedded gen etic algorithm, sensitivity analysis and similarity measure of the judgemen ts done by decision-makers. Consequently, the consensus of all the elements in the comparison matrix can be obtained through such an innovative approa ch to resolve the disparity of judgements within decisionmakers.
