Abstract
In this study, we aimed to proposal of the decision making support system for mobile phone replacement demand. The system shows simple questions about selection criteria of product to users. Thus, the system could recommend the product that matches the user's preference. First, we adopted the Fuzzy AHP that can reflect people's subjectivity. Because, we think that it can be flexible decision making support. And, we set the evaluation value of alternative (mobile phone) by the paired comparison method. We think that our system can support the answer of decision making problem in the mobile phone replacement demand. So, users would have confidence to the answer. And, they would be able to do better selection of mobile phone. In this paper, we show the experiment and results using the Fuzzy AHP. And, we propose and verify the decision making support system.
