This study aims to develop a hybrid risk prioritization approach for Fine-Kinney by combining generalized TODIM, best-worst, and interval type-2 fuzzy set to address the limitation of experts' evaluation under uncertain environment.
The risk prioritization process is one of the most crucial steps for risk evaluation of potential hazards. The Fine-Kinney method has been commonly applied to controll risks in practice, while the classical Fine-Kinney has limitations in the determination of important degrees of risk parameters. In addition, current risk prioritization approaches for Fine-Kinney overlook the bounded rational behavior of expert within the uncertain context, especially, the high uncertain environment. The purpose of this paper is to develop a hybrid risk prioritization approach for Fine-Kinney by using generalized TODIM (an acronym in Portuguese of interactive and multi-criteria decision making), best-worst, and the interval type-2 fuzzy set. First, the linguistic terms and interval type-2 fuzzy numbers are adopted to handle the expression problem of the team members' uncertain evaluation information. Second, in order to obtain the objective weights of risk parameters, the best-worst method is proposed to determine the relative importance degrees of risk parameters. Third, the interval type-2 fuzzy numbers are incorporated into the generalized TODIM method to determine the risk priority orders of hazards, which can simulate the experts' bounded rational behavior under uncertain environment. Finally, a practical risk analysis example of ballast tank maintenance and the sensitivity and comparison analysis is presented to demonstrate the application of the proposed Fine-Kinney framework. The sensitivity analysis and comparison are employed to validate the reliability of the new risk prioritization model.
