Methods of Safety Risk of Marine Network System of the Evaluation Based on Fuzzy Set and Entropy Weight Theory

In view of the special nature of the marine network security, this paper is mainly based on the fuzzy set theory and entropy weight to some aspects of the network security risk assessment, and gives the description of scale, constructs the membership degree matrix of the corresponding evaluation factors, entropy weight coefficient method is used to determine the factor weights to reduce the traditional weight method for subjective deviation, Using system synthesis method, the safety risk value of each element of integration and then decides the grade of Marine network system security risk. The example analysis shows that the method is feasible and effective.
