Multi-objective decision making by AHP and its application to personal preference retrieval system

Abstract

Because the web based retrieval systems have a limitation related to their conditions where a user has to select the prepared list, the obtained answers are not always corresponding to his/her feelings. In order to solve such a problem, we consider that the input method of retrieval conditions by the fuzzy utility function and the priority determination method of the reference conditions by multi-objective decision making theory and AHP model. In this paper, we constructed the marriage arrangement system to verify the effectiveness of the combination method. In the system, 10,000 people records are randomly drawn up and two-stage selection is implemented. As a result, five people are selected based on user's taste information.
