[目的]为从宏观及微观角度建立考察多维指标舰载雷达的可靠性、维修性、保障性(RMS)评估模型,查找制约其效能发挥的薄弱环节,提高任务的成功性,确立基于多智能体的RMS仿真评估建模总体思路。[方法]首先,对雷达运行状态及内部结构进行分析,建立“任务−装备−保障资源”的RMS评估模型,并将其映射成不同智能体类型;然后,基于多智能体技术,对装备袭运行状态的动态变化、维修保障机制和评价指标输出进行建模,确立基于多智能体的雷达RMS仿真评估系统。最后,以某型相控阵雷达天线阵面为例,开展RMS评估仿真建模与分析。[结果]仿真得到天线阵面任务成功率和与RMS相关的评估参数,证明了基于多智能体的雷达装备仿真评估方法的可行性。[结论]所提评估方法可为舰载雷达装备的RMS设计改进奠定基础,以及其他舰载装备的RMS评估研究提供参考。

[Objective]To establish a reliability,maintainability,supportability(RMS)assessment model for shipboard radar from macro and micro perspectives,find the weak links that restrict the enhancement of radar effectiveness,and improve the mission success of shipboard radar,this paper proposes the general approach of a multi-agent-based RMS simulation assessment model for shipboard radar.[Methods]Through an analysis of the radar operation status and internal structure,a mathematical model of"mission-equipment-support resources"RMS assessment is established and mapped into different agent types.Based on multi-agent technology,the dynamic changes of equipment operation status,maintenance support mechanisms,and assessment index output are modeled,and the multi-agent-based RMS simulation assessment system is established.Combined with typical examples,the RMS evaluation modeling of a type of phased radar antenna array is carried out.[Results]The simulation obtains the mission success rate and RMS-related assessment parameters of the antenna array,which verify the feasibility of the multi-agent-based radar simulation assessment method.[Conclusion]The results of this study lay the foundation for the scientific RMS design improvement of shipboard radar equipment,and provide references for research regarding other shipboard equipment.
