Optimal Location Selection of Temporary Accommodation Sites in Iran via a Hybrid Fuzzy Multiple-Criteria Decision Making Approach

Abstract

The aim of this study is to determine and prioritize the factors affecting optimal location of temporary accommodation sites. Using the opinion of experts and the Fuzzy Delphi method, three main criteria including infrastructural factors, access, and sustainability and 11 subcriteria are identified. To specify the weight of the identified factors, the fuzzy DEMATEL-based analytic network process (FDANP) method is used. After applying this technique, it is determined that the main criterion of access has the greatest weight among the main criteria. Finally, District 6 of Tehran Municipality has been considered as a case study to represent the efficiency and applicability of the proposed method. According to conducted research on different scenarios of earthquake activity in Tehran, the number of displaced people requiring shelters, the area of required space, and suitable places for the construction of temporary shelters are determined. The alternative locations have been ranked using the linear assignment method, and the best prioritized sites to establish temporary shelters for two assumed cases of temporary accommodation are presented.
