The evolution of the Warships Equipment Maintenance and Support System is the result of the internal and external factors.Based on the analysis of the composition of Chinas Warships Equipment Maintenance and Support System and its evolutionary motivation system, based on the system dynamics theory, the evolution model of the system is established and simulated.It lays the foundation for model research for the prediction and control of the evolution of the system.The simulation results indicate that increasing financial input, especially in the initial stage of system evolution, increase maintenance hardware investment and personnel input, and increasing personnel input during the jump period, in the middle and late stages of system evolution, improving the research and design participation of maintenance personnel will bring greater evolutionary benefits.
