System life evaluation of warship equipment based on comprehensive contribution rate
In order to more scientifically predict the life of equipment and improve the operational effi-ciency of equipment,the evaluation method of"system life"of warship equipment was explored from the perspective of"comprehensive contribution rate"of equipment to the system.Firstly,based on the combat ring theory and the nonlinear structural equation model,the quadratic interaction term was in-troduced to establish the combat capability index system and the evaluation model of the combat effec-tiveness of the warship equipment system.And then,a complex network model of warship equipment system was established by using the threshold method.Based on the statistical values of topological features,an index system of battle structure characteristics of warship equipment system was con-structed.The index weights were calculated by combining the analytic hierarchy process and entropy weight method.Finally the definition and mathematical model of the comprehensive contribution rate and system life of warship equipment system were put forward.Taking the aircraft carrier formation system confrontation as an example,the feasibility and effectiveness of the model and method are ve-rified by the experimental simulation data.
