Optimal Selection Model for Life Emergency Rescue Ship Based on Game Theory and VIKOR Method

This paper proposes a new model for optimal selection of the emergency rescue ship, aiming to select the suitable surrounding ships within the accident sea area as the emergency rescue facilities. Firstly, the combined weights of indicators for the selection of emergency rescue ships need to be determined. The Analytic Hierarchy Process (AHP) method is used to determine the subjective weight. The Criteria Importance Through Inter-criteria Correlation (CRITIC) method is used to determine the objective weight. Based on the idea of game theory, the subjective and objective weights are fused to obtain the combined weight. Secondly, the Vlse Kriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method is introduced to sort the rescue ships. Finally, an example is used to verify that this model is reasonable and effective for the selection of maritime rescue ships.
