A Combined GIS-MCDM Approach to Site Selection of Temporary Shelter: A Case Study in Dahab, Egypt
Year: 2025
Type: article
Abstract: In this study, a model based on the Geographic Information System (GIS) and MCDM method: the Criteria Importance through Inter-Criteria Correlation (CRITIC) based type-2 neutrosophic numbers (T2NN) is used to give researchers and stakeholders a simple and reliable spatial decision-making tool. First the model focuses on determining a group of experts with experience related to the study. The selected group of experts then determines effective objectives and attributes concerning the study and estimates the relative importance of each objective and its related set of attributes using a set of linguistic variables. The T2NN-CRITIC method was used to evaluate the objectives and attribute weights and importance. Second, the spatial attribute layers were integrated with the global weights evaluated using ArcGIS Pro to rank and choose the most suitable site for the study. The proposed model was implemented through a case study to select the most suitable site for temporary shelter in case of floods in Dahab, Egypt. According to the analysis of the current study, 5.16% of the study area (17,550 Km2 ) is highly suitable as a site for a temporary shelter in the event of a flood in Dahab, Egypt, (126,570 Km2 ) of the study area classified as moderately suitable, (161,850 Km2 ) of the study area classified as marginally suitable and, finally (34,080 Km2 ) classified as not suitable. Finally, sensitivity analysis has been used to confirm the stability of the model results.
