Abstract:

The safety of submarine underwater navigation is affected by both the performance of submarine itself and the marine environment, so it’s analyzed how the various factors impact on the submarine navigation safety. Then the indicators are determined, and the submarine navigation safety evaluation index system is established. The submarine navigation safety assessment is consistent with super-standard weight, and marine environment data are fuzzy in some extent, so the fuzzy comprehensive evaluation method based on super-standard weight is taken to evaluate the submarine navigation safety. Finally, the evaluation process is demonstrated by a practical example.
