Action selection via weighted TOPSIS method based on fuzzy Fine Kinney risk analysis for gas plant

Risk analysis is of great importance as it ensures that the necessary measures are taken by predetermining the hazards that may cause work accidents and occupational diseases. The most widely used risk analysis method in practice is the Fine Kinney method. In this thesis, the hazards occurring in a medium-sized gas filling facility were defined and the risk scores of these hazards were determined by the expert team according to the Fine Kinney risk analysis method. However, since the same risk significance level is obtained in different combinations of scale values in the classical Fine Kinney risk analysis method and the characteristics of the company applied in the risk analysis are not taken into account, the hazards were evaluated using Fuzzy Fine Kinney risk analysis and the most critical hazards were determined. Action plans are defined for critical hazards determined as a result of Fuzzy Fine Kinney risk analysis. Among the actions that require labor and/or budget, the action selection was made with the TOPSIS method, taking into account their relationship with the hazards. While applying the TOPSIS method, the importance levels of the groups affected by the hazards were determined by AHP and these AHP weights were reflected in the TOPSIS method and actions were determined.
