A Hybrid AHP-QRVE Model for Consistency Verification in Property Valuation
Downloads
The conventional Quantitative Rating Value Estimation (QRVE) method for building valuation often introduces bias because it relies heavily on subjective Likert-scale ratings. This study aims to address the inherent weaknesses of Likert scales used in the QRVE method by mitigating the threshold ambiguity and appraiser cognitive inconsistencies. This study proposes a hybrid methodology by integrating the pairwise comparison matrix from the Analytic Hierarchy Process (AHP) into the QRVE framework. The mathematical foundation of AHP transforms absolute assessments into relative ones, with the Consistency Ratio (CR) serving as a verification metric through the induced matrix ( represents the total number of evaluated properties (including the subject property). The analysis results show that the AHP-QRVE integration successfully detects valuation errors and inconsistencies between comparable objects when applying conventional Likert scales. Through numerical simulations, this method has provided more objective assessment outputs, even greater audit transparency for the Public Appraisal Services Office.
