Research and application on risk assessment quantitative method based on fuzzy AHP

The risk assessment is an important means to obtain the status of system security and an important basis to develop security solutions as well. For there are a lot of uncertainty in the index value of the risk factors, using the improved fuzzy AHP system model to carry out analysis and evaluation combined qualitative and quantitative, achieving the index quantified for system security risk factors, and selecting the ship integrated navigation system as the study examples to validate. The analysis shows that it is a practical method to certain extent.
