大型复杂武器系统可靠性和维修性指标的总体优化方法

可用性是装备效能的重要组成部分,是装备常规技术性能得以发挥的前提。通过对大型复杂武器系统层次结构和可用度基本关系式的研究,采用数学分析方法确定了各分系统可用度指标协调改进的基本原理。研究了在工程实践中,各分系统的指标改进难度对改进次序的影响,设计了分系统级可用性和设备级可靠性维修性指标优化的计算方法并确定了算法流程。采用Matlab编程,以某型舰为例,检验了算法的可行性与有效性,给出了完整的计算示例,从而可为以最小的代价实现和改进装备总体可用度指标,使各分系统所属设备的可靠性和维修性指标形成一个整体的要求,提供理论依据和方法。

Overall Optimization of Reliability and Maintainability of Major Weapon System

The availability is an important part of weapon system effectiveness, and also the prerequisite for achieving the conventional technical performance. By the discussion of the hierarchical structure of weapon system and the basic formulas for its availability, a fundamental principle of coordinating and improving the availability indicators among different subsystems is proposed based on mathematical analysis. The effect of improving difficulty of subsystem availability on improving order is discussed according to engineering practice. And an optimization method and its algorithm are designed for subsystem availability, equipment-level reliability and maintainability. Furthermore, based on a type of navy vessel, the feasibility and validity of the proposed algorithm are verified by Matlab programming. A theoretical basis and implementation approach are provided to obtain and improve the total availability with minimum cost, and take different equipment reliability and maintainability of different subsystems as an integration indicator.
