In this paper, risk evaluation of Landslide using the Analytic Hierarchy Process (AHP) is introduced. AHP, which was established by Thomas L. Saaty in 1971, is decision-making method based on a pair comparison. Since its proposal by Saaty, the of evaluation standard the AHP method has been as an extremely technique in many evaluation method. However, in order to make decision using by ordinary AHP, it needs paired comparison with not only criteria but also alternatives. Therefore, we propose that to apply the AHP of an absolute evaluation method to risk evaluation in this paper. Here, first of all, the basic AHP of a relative method is described using ordinary simple example. Next, the main characteristics of the relative and absolute methods are summarized. Then we describe how to adopt AHP method to risk evaluation system using the example data to estimate of people’s ages. Moreover, Japanese inspection sheet for landslide risk evaluation system which use their aerial photography using absolute method of AHP is explained. Last we will consider a framework for converting implicit knowledge into explicit knowledge through these AHP algorithm. |
