摘　　要：针对助航灯光系统定期维护方式下维护成本高且可靠性难以保障的问题,建立基于相对劣化度的预防维护决策模型。依据助航灯光系统运行参数的特性,提出助航灯光系统相对劣化度的评定方法,综合考虑相对劣化度对失效率和维护成本的影响,研究助航灯光系统预防维护的策略,建立预防维护决策模型。对失效率符合威布尔分布的跑道边灯外场回路进行预防维护算例分析,结果表明,该模型能为助航灯光系统的维护计划提供决策支持。Aiming at the high cost and unavoidably decreasing reliabilities of age-T policy in airfield lighting system, a preventive maintenance （PM） model is established. The evaluation method of relative-deterioration is proposed, which is based on the characteristics of working parameters in airfield lighting system. By considering the effect of relative-deterioration on failure rate and cost, the PM strategy is studied and the PM model is established. The simulations are implemented on the runway edge lighting system, which follows Weibull distribution in failture function. The approach is verified to be effective and valuable to PM schedules decision.
