    Abstract

    A case-based reasoning model is proposed, where experience is included in all processes of construction cost estimating by the analytic hierarchy process. The model overcomes the difficulty of measuring experience for determining the weights of attributes. The accuracy of three different models was compared. The model using the analytic hierarchy process was more accurate, reliable, and explanatory than the other models, and closer to the original aim of the case-based reasoning model, for solving new problems using experience from previous cases.
