Abstract
This research aims to present the temporary shelter-site selection during fine-particulate matter with a diameter of 2.5 microns (PM 2.5) air pollution disaster via the Analytic Hierarchy Process (AHP) for Chiang Mai University case study. Firstly, the main criteria and sub-criteria for the evaluation of alternatives were set by interviewing the experts who have experiences about PM 2.5 shelter construction. Then, a suitable area for temporary shelter-sites was
identified by distributing the 617 questionnaires in order to seek a suitable area based on the demand for services. After the survey of the suitable area, the three-temporary shelter-site candidates were sought based on the consideration of the criteria from the interview of the experts, and the preliminary data of three candidates were collected. Next, the AHP was applied for selecting the temporary shelter-site. Finally, the results were analyzed and the primary guideline of the temporary shelter which obtained the highest score was proposed for constructing the temporary shelter. The results of this research found that the main criteria consist of room function, cost, accessibility, room character, and public utility, respectively. The most suitable temporary shelter-site based on three candidates was the room on the 4th floor at CMU's main library. Owing to the application of AHP, we found that this technique can help the decision-makers to select the suitable temporary shelter under the specified criteria and this research method can apply to other cases for the location selection.
