Modelling and Structure Optimization Analysis of Warship Damage Control Command Information System

The suddenness and rapidity of modern warship disasters have been significantly intensified, and higher requirements have been put forward for the information level of the damage control (DC) command network. Based on the complex network characteristic analysis of DC command information system, the paper developed the network topology model and the performance evaluation index of the command system, pointed out the defects of the current model structure; also, it put forward a kind of structural optimization thought: dividing the DC command information network into command subnet and a unified monitoring control subnet, both of the subnets were optimized independently and then combined again; finally, it compared and analyzed the optimization effects of different optimization algorithms on command subnet and monitoring control subnet through an example. The simulation results showed that the performance of the optimized DC command information network is fully improved. It will be the focus of subsequent research to develop a structure optimization algorithm that comprehensively considers the properties of nodes and optimization costs, seek the end criterion of network structure optimization process, analyze the coupling relationship between subnet connection mode and the whole network structure optimization effect, and realize the integrated optimization path of network structure.
