Simulation on design-oriented missile equipment support system under multiple disturbances
Xibei Gongye Daxue Xuebao, 2022 针对导弹装备, 尤其是新研装备或历史经验数据欠缺的装备, 在设计阶段保障方案规划不合理的问题, 提出了一种多扰动下面向设计的导弹装备保障系统仿真方法。构建了分层分块的混合递阶仿真框架, 抽象出装备保障过程中的装备类、保障类、管理类、环境类智能体, 并根据保障流程确定了这4类智能体的交互机制及信息传递链路。分析了影响装备保障决策的2类扰动, 建立了装备故障扰动和人员失误扰动模型, 采用双时钟机制实现仿真过程中的扰动注入, 并根据装备维修保障流程及智能体状态跃迁过程建立了保障系统的恢复行为模型 ...
