8404 以天线阵面T/R(transmit/receive)组件为出发点,当其故障单元达到k/N系统的阈值,而其他单元尚未达到阈值时,雷达停机开始换件维修,建立了以系统的供应可用度为约束条件,备件费用最少为优化目标的配置模型,并利用边际效应算法对各参数进行求解。 With antenna array surface T/R (transmit/receive) components as a starting point, when the failure unit to achieve the threshold value of k/N system, and other units have not reach the threshold, radar began to change maintenance downtime, established for the supply of system availability constraints, the configuration model of the spare parts cost minimum as the optimization goal, and use the marginal effect algorithm for solving the parameters.
8405 实例运算结果表明该模型合理可行,能为备件配置提供理论支撑。 Example computation results show that the proposed model is feasible, can offer theory support for spare parts configuration.
8406 针对传统装备重要度评估方法在解决动态评估方面的不足,提出一种考虑权重演化的装备重要度动态评估方法。 In view of the traditional equipment important degree evaluation method in solving the dynamic evaluation is not enough, considering the evolution of weight is a kind of equipment important degree of dynamic evaluation method.
8407 基于多维关系复杂网络建立装备体系的结构模型,综合考虑各个装备之间的指控关系、空间关系和协同关系,将装备体系的变化转化为复杂网络的权重演化,并针对不同关系网络的特点,分析各个关系结构的权重演化过程,分别构建动态评估指标。 Complex networks based on multidimensional relation equipment system structure model is established, considering various charges, spatial relations between the equipment and cooperative relations, and converting equipment system changes to the weight of a complex network evolution, and in the light of the characteristics of different relational network, the weight of each relationship structure in the analysis of evolution process, building dynamic evaluation index respectively.
8408 最后,通过构建某营执行进攻作战任务的算例,验证了该方法的合理性和先进性。 Finally, by building a camp offensive operations tasks of example, the rationality of the proposed method is verified and advanced.
8409 针对发动机推力受限和动态延迟的制导问题,设计了一种具有鲁棒性的非奇异滑模制导律,并证明了有限时间收敛条件。 In view of the limited engine thrust and dynamic delay guidance problem, we design a robust nonsingular sliding-mode guidance law, and proves that the finite time convergence condition.
8410 首先,基于平面弹-目相对运动学关系,建立了考虑发动机一阶动态延迟的弹-目相对运动数学模型。 First of all, based on the planar elastic - relative kinematics relationship, set up to consider the engine first order dynamic delay play - orders, a mathematical model of relative movement.
8411 其次,基于有限时间理论,证明了推力受限下制导律有限时间收敛条件及其性质; Secondly, based on the theory of finite time and proves the limited thrust guidance law under the finite time convergence condition and its properties;
8412 并推广到动态延迟情况下,设计了非奇异滑模制导律; And promote the dynamic delay cases, designed the nonsingular sliding-mode guidance law;
8413 最后,用边界层函数代替符号函数去除抖振。 Finally, using boundary layer function instead of sign function to remove the chattering.
