Abstract: Networked operational equipment system is a typical complex system with multiple elements,close correlation and dynamic evolution,and brittleness is an inherent property that directly affects its safety and operational stability.Aiming at networked operational equipment system’s characteristic of multiple constitution and complex correlation,firstly,concepts of equipment nodes,correlation relationships and networked operational equipment system are defined,and networked operational equipment system structure is abstracted.Brittleness transmission mechanism is analyzed and brittleness control causal circuit diagram is designed.And then,differential dynamic model of brittleness control is built.Secondly,immune control strategy,isolation control strategy and integrated control strategy are put forward separately,and the measurement method of brittleness control effect is given.Finally,taking networked air defense operational equipment system as example,dynamic effect of brittleness risk control threshold,pulse control coverage number and composite control strategy parameters to overall brittleness risk degree are simulated and analyzed.According to the simulation results,when brittleness risk control threshold is improved 25%,the brittle risk durations of immune control strategy,isolation control strategy and integrated control strategy are reduced respectively 53.2%,44.9% and 42.2%,and the brittleness risks are improved 24.5%,1.5% and 20.4%.When pulse control coverage number is doubled,there is no significant difference in the duration of high brittleness risk,and the brittleness risks are reduced 9.3%,1.5% and 10%.When the ratio of parameters of integrated control strategy is increased about 1.3 times,the duration of high brittleness risk and the brittleness risk are reduced 5.9% and 8.3% respectively.The research results verify the feasibility and effectiveness of the model and strategies,which provide a new idea and method for exploring the brittleness control process and low of networked combat equipment system.
