摘要

实现高可靠性是军用车辆未来作战系统(FCS)系列发展的主要目标之一。实现这一目标的拟议解决方案是基于预测的方法,其特点是能够监测关键任务部件的状态并预测FCS系统的未来状态。本文分析和比较了实现和维持军事系统高可用性的两种方法:大修和预测资产管理策略。结果表明,预测方法通过预测故障和减少行政和后勤延误,提高了操作可用性。此外,预测功能允许智能维护,即仅更换剩余寿命达到临界值的部件。在这种情况下,与大修维护策略相比,改进的操作可用性以显著降低的成本(备件数量)实现。预测方法还降低了即将执行任务期间的失败风险,因为它允许战地指挥官只选择那些剩余寿命超过即将执行任务期限的平台

Improving reliability and operational availability of military systems
Achieving high reliability is one of the major objectives in the development of the future combat system (FCS) family of military vehicles. The proposed solution to achieve this objective is a prognostics-based approach characterized by a capability to monitor the status of mission-critical components and forecast the future state of the FCS system. In this paper, two approaches for achieving and maintaining high operational availability of military systems are analyzed and compared: overhaul and prognostics asset management strategies. It is shown that the prognostics approach leads to improved operational availability by anticipating failure and reducing administrative and logistics delays. In addition, the prognostics capability allows intelligent maintenance that is, replacing only those parts whose remaining lifetime reached the critical value. In this case, the improved operational availability is achieved at a significantly lower cost (number of spares) compared to that of the overhaul maintenance strategy. The prognostics approach also leads to a reduced risk of failure during the upcoming missions, since it allows field commanders to select only those platforms whose remaining life exceeds the duration of the upcoming mission
