Abstract

One of the important issues after an earthquake occurrence is to transfer residents to temporary accommodations. These points are areas of the city that have a higher safety factor against earthquake reoccurrence and have good access to management and relief centers. Due to the critical condition in the area after the earthquake, with the transfer of the township to these areas, relief procedure can be achieved with the highest speed and minimum risk. The purpose of this study is to determine the suitable locations for the construction of temporary accommodation facilities for injured people after earthquake occurrence in Karaj. To this end, firstly, the main controlling parameters in selection of the appropriate places for temporary accommodation are determined, and are classified into two groups of the main criteria of compatibility and incompatibility. The total number of the sub-criteria are twelve. Due to the spatial nature of this problem, fuzzy logic system with multi-criteria decision-making method is used to determine the most suitable points. After fuzzification of the criteria, their participation weight is determined and then, they are prioritized using fuzzy hierarchical analysis method. In the next step, desirability map of the region is prepared for each of the criteria. Eventually, by combining the impact of the studied criteria, a descriptive map of the region relative to the points of interest for temporary accommodation is generated. Based on this map, seven points are selected as suitable points for the construction of a temporary accommodation camp, and by employing the analytical hierarchy procedure with Expert Choice software, the optimal point is chosen.
