Deep Security Analysis of DCS for Ship's Nuclear Power System based on Improved DEMATEL

Abstract

The deep security of DCS(Distributed Control System) is more serious than conventional hardware problems for ship's nuclear power system. It is great significance to study the DCS deep security for operation security of ship's nuclear power system. The main characteristics of DCS deep security are obtained by comparing and analyzing the ship's nuclear power with the conventional control and information system. The DCS deep security protection system is constructed, and an improved DEMIAL method is used to analyze center degree and cause degree of the system elements. The improved scale model is proposed to construct direct relationship matrix based on Weber-Fechner law. Weights are used to synthesize multiple decision-making opinions. The main concerns of deep security protection and the system elements with large influence are analyzed. The results of the DCS deep security factors model, the protection system and the protection system elements of ship's nuclear power system, can provide valuable support for the follow-up research on the deep security technology and system of ship's nuclear power system.
