Evaluating earthquake vulnerability of 2023 Kayseri, Türkiye via BWM-ABAC method

Effective earthquake disaster management requires the most recent and precise vulnerability evaluation. There are a total of 24 faults and 16 fault segments that may affect Kayseri city center and its districts. According to the records, in the historical and instrumental period, more than 30 earthquakes that occurred with a magnitude of 4 and above are concentrated in 8 districts. Ten of these earthquakes occurred in the last 7 years. A framework for evaluating Kayseri’s earthquake vulnerability has been presented using a three-stage process: Determining the criteria through a literature review and consultations with experts, applying the linear Best Worst Method (BWM) to weigh the selected criteria, and evaluating the districts using alternative by alternative comparison (ABAC), respectively. To analyze the earthquake vulnerability of districts, the proposed methodology BWM-ABAC, which is used for the first time in the literature, offers valuable results. The findings showed that the Kocasinan district is the most vulnerable to earthquakes in Kayseri City. A sensitivity analysis was then performed to confirm the robustness

Logistics competitiveness of OECD countries using an improved TODIM method

The Organization for Economic Co-operation and Development (OECD) provides a forum where governments can work together to increase the global welfare and to seek solutions to common problems through economic growth, where logistics plays an important role and contributes to financial stability. Evaluation of the logistics competitiveness of countries is a technical decision-making issue involving a variety of criteria. Most importantly, these criteria usually conflict with each other and they often act and react upon one another. As in logistics competitiveness as well as in many decision-making problems, the relationships among criteria are interdependent. Moreover, different dimensions and criteria weights also affect the evaluation results. By considering these situations, in order to handle these criteria interactions, Mahalanobis distance (MD) based TODIM (an acronym in Portuguese for Interactive and Multicriteria Decision Making) method has been developed and it has been applied to evaluate the logistics competitiveness of the OECD countries. Evaluation of the correlation between criteria develops the consideration outcomes (regarding sorting) to a certain degree with the traditional TODIM method
