Reducing inconsistency measured by the geometric consistency index in the analytic hierarchy process

摘要: Abstract This paper presents a theoretical framework and procedure for revising the judgements improving inconsistency of an Analytic Hierarchy Process (AHP) pairwise comparison matrix when Row Geometric Mean (RGM) is used as prioritisation Consistency Index (GCI) measure. Inconsistency improved by slightly modifying that further reduce GCI. Both derived priority vector will be close to initial values. A simulation study utilised analyse performance algorithm. The proposed allows specification particular interests. numerical example illustrates procedure.
