In this part, we simulated the basic data of three ships according to the risk assessment indexes to verify the feasibility of new methods. In the future, these methods can be tested in a more realistic environment. Here ship 1 to ship 3 are used to represent three different ships. Risk assessment index data of the three ship areas are shown in Table 6 under n-value neutrosophic information.
