[Objectives]The suddenness and rapidity of modern warship disasters have 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 a DC command information system,its network topology model is constructed.[Methods]Aiming at the shortcomings of the current model,based on the stochastic networking method and considering the node attributes of the DC command information network and the cost of increasing network density,a structural optimization method for optimal stochastic networking is proposed,and the specific optimization process is demonstrated by case simulation.[Results]The results show that the command and facilities subnets have different influences on network performance,and the improved random networking method performs better than the traditional random method in network structure optimization.[Conclusions]Subsequent research can start by changing the connection mode between subnets to solve the problem of the terminal node of the command subnet being too high,thereby further improving the comprehensive performance of the DC command information network.
