階層化ファジィ積分（HFI）による「もの」「サービス」の総合評価法の提案

－高齢者施設の選択を例に－

抄録

This paper uses Hierarchical Fuzzy Integrals (HFI) for comprehensive evaluation models with interaction among evaluation criteria and an extended version of the Analytical Hierarchy Process (AHP) model. First, we show the structure and computational procedure of HFI models on a single-level hierarchy diagram. A sensitivity analysis with interaction degree shows that the selected facility is different depending on the interaction degree. Second, we extend the multi-level hierarchical model and present its computational procedure. We select the model that includes Kansei evaluation items and propose the standard hierarchical relationship and standard interaction degrees using the facility selection model for the elderly. Lastly, we provide some remarks for identifying individual evaluation scores.
