A study of ship integrated navigation system risk assessment based on fuzzy analytic hierarchy process

The risk assessment is an important means to obtain the status of system security and an important basis to develop security solutions as well. Taking the integrated navigation system as the research object, this article establishes the risk assessment index system based on the analysis of the composition and the characteristic foundation of the integrated navigation system, carrying on the assessment with the combination of qualitative and quantitative analysis through improved fuzzy AHP system and verifying with examples. The analysis shows that it is a practical method to certain extent.
