Risk assessment method for marine network security base on fuzzy-gray system theory

摘要

This paper constructs a marine network risk assessment model based on fuzzy-gray system theory, combining fuzzy mathematics with gray system theory. According to some special characters of the Marine Network, we screened the score results and normalized on the index weight with expert scoring. Where after, we analyzed the safety index and the object and established gray evaluation matrix based on gray relation analysis theory. Finally we assessed the security of the Marine Network with 2-levels fuzzy comprehensive evaluation method. The method was demonstrated much more scientific, subjective and effective.
