Özet:

In this study, the issue of housing selection, which is one of the important decisions of human life, is discussed within the scope of Istanbul province with a risk-based approach. When studies in the literature focusing on housing selection are examined, it is seen that there exist applications that are within the scope of various decision criteria. However, each choice of housing is a vital and difficult decision to make under the different needs of the region. In a residential area located in an earthquake zone such as Istanbul, earthquake risk will be an extremely important decision criterion. In the application, clustering analysis is applied to group the neighborhoods in Istanbul according to their risk levels. The earthquake risk criterion is weighted using the Analytical Hierarchy Process method based on extensive literature review and other criteria obtained from online real estate institutions and expert opinions. By using these weighted criteria, a sample house selection ranking is obtained by the VIKOR method. The ranking process is carried out in two separate ways, including and not including the new risk criteria in decision analysis. As a result of the comparative analyses, it is emphasized that the earthquake risk, which is determined as a new decision criterion for housing selection, should be taken into account as much as other economic, physical and social decision criteria.
