摘　　要：综合气象观测系统运行监控平台(ASOM)是地面观测设备实时运行状态及探测数据的监控保障系统,文章基于ASOM中2009年12月1日至2014年11月30日的维护维修数据对新一代天气雷达运行指标进行评估,统计其业务可用性(A_o)、平均无故障工作时间(MTBF)、平均故障持续时间(T_(fd))、故障次数(N_f)和故障分布情况,2014年,A_o和MTBF分别提高到99.06%和1465.08 h,T_(fd)和N_f分别降低至13.15 h和4.68次。此外文章对故障案例中的备件更换情况按照雷达分系统和不同型号进行统计分类,建立针对性的备件供应管理,以提高新一代天气雷达的维修能力,提升综合观测系统装备供应管理效能。Atmospheric observing system operations and monitoring （ASOM） is a real-time monitoring system of observation equipment＇s running status and observation data. In this article, four operating indexes including availability of operation （Ao）, mean time between failures （MTBF）, failure duration （Tfd）, number of failures （Nf） are evaluated on the basis of maintenance data of ASOM from 1 December 2009 to 30 November 2014. For the 2014 indexes, Ao and MTBF increase to 99.06% and 1465.08 h respectively while Tfd and Nf reduce to 13.15 h and 4.68 times. In addition, the failure distribution and replacement of radar spare parts in these fault cases and their trends are quantified and evaluated for different radar subsystems and different types of radar. The results, to some extent, make efforts to set up pertinent spare parts supply management, improve maintenance support capability of CINRAD, and, eventually, promote efficiency of China＇s meteorological observation equipment management.
