大型武器装备总体战备完好性的多层次协调优化

通过对大型武器装备多层次结构及指标特点的分析,提出了一种基于多维映射的建模分析方法,分析了总体战备完好性指标和分系统设备指标之间的传递关系,建立了技术经济代价最低且指标能够满足要求的总体战备完好性多层次协调优化分配模型。以大型舰船为例,根据对舰船系统的使用强度分析,确定了各系统设备的可靠性维修性指标范围,以此作为模型的输入数据。根据模型多变量全局优化的特点,通过基于浮点数编码的遗传算法对典型示例进行了计算,经过权衡分析后得到了理想的协调优化方案,并对计算结果进行了综合分析和讨论,为大型武器装备的论证研制、总体设计和使用保障提供了依据。

Multi-level coordinated optimization of major weapon equipment’s overall operational readiness indicators#br#

With analyses of multi level structure and indicator’s characteristics of major weapon equipment, a modeling and analysis method based on multi dimensional mapping is proposed. The transitive relationships between overall operational readiness and indicators of subsystem and its equipment are discussed. The multilevel coordinated optimization allocation model of overall readiness indicators which can meet all the requirements and get the lowest technical and economic cost is explored. With the example of the navy vessel, the indicator requirements of different equipments’ reliability and maintainability are established based on operation intensity of the navy vessel’s subsystems, which are considered as the model’s input data. According to the multivariate optimization characteristics of the model, typical examples are selected and calculated with the genetic algorithm based on float encoding (FEGA). An excellent coordinated optimization allocation solution is obtained based on trade off analyses, meanwhile, indicators in the allocation solution are also analyzed comprehensively. The upper results lay a foundation for the design, development and certification test of the major weapon equipment.
