Global Risk Management Index Assessment: Application Of Grey-Based Topsis Method

The Global Risk Management Index (INFORM), created in cooperation with the European Commission, develops analytical findings to support decision-making processes related to humanitarian crises and disasters, helping countries make decisions at the stages of the disaster management cycle. This index, which can support the success of countries in disaster management, has been discussed in a limited number of studies and needs to be adequately tested empirically. This study aims to create a new ranking with an MCDM method that allows the INFORM Risk Management Index to be evaluated within a specific time frame. For this, the TOPSIS-G approach is proposed. With the proposed model, the 9-year INFORM performances of the countries were analyzed, and the results were compared with the current rankings. In the study, 19 countries were included in the evaluation. The data set for these countries was obtained from the INFORM reports published by the European Commission in 2015-2023. The 9-year risk management performance was analyzed with the model proposed in the study. In addition, due to the inclusion of the time dimension in the evaluation stages, a new risk management performance ranking of the countries was created. Country rankings obtained using the TOPSIS-G approach were compared with current INFORM rankings using Spearman and Kendall Tau-b nonparametric correlations. The results show a high correlation between the two rankings. According to the INFORM ranking, for the countries covered in the study, the areas that need improvement in the disaster management stages were noted, and suggestions were made.
