舰载机着舰引导装备体系系统级备件保障研究

针对舰载机着舰引导装备体系中备件构成复杂、数量众多,传统单元级备件保障效果单一,无法高效、全面评估整个备件系统的问题。引入k/N(G)表决关系把复杂系统等效分解为串并联结构；提出备件保障概率、使用可用度、利用率等关键性指标在不同种备件寿命分布类型下的预测模型,针对任务结束后才能统计得出指标数据的不足,利用解析计算方法实现预先评估备件方案,提高备件保障效果；并进一步给出系统级各指标计算方法。通过算例分析,与传统方法相比提高了该体系系统级备件保障方案制定的精度与综合评估能力,同时仿真结果符合实际情况。

Research on System Level Spares support of Shipborne Aircraft Landing Guidance Equipment System

Aiming at the deficiencies of carrier based aircraft landing recovery guidance equipment system support capability. This paper propose a comprehensive weighting method for evaluation based on Group Analytic Hierarchy Process(GAHP) and entropy method. In order to consider the impact of subjective and objective factors on the evaluation system. Aiming at the evalution object has the characteristics of fuzziness and uncertainty. Based on cloud model theory, the quantitative index cloud model representation is obtained . Using weighted deviation, so that the evaluation of the support capability of the system can realize the mutual conversion between quantitative and qualitative. At the same time, make the evaluation result more intuitive and suitable for decision making. The simulation result verify the effectiveness and advantage of the propoesd evaluation method.
