本文介绍了一个庞大的设施设备数据库的一部分，其中包含超过100000个电力、机械和电子部件的故障和维护信息。出于对关键基础设施恢复能力的既得利益的驱使，美国陆军工程兵团收集了这些数据。供暖、通风和空调（HVAC）设备在数据库中有很好的代表性。大约13000个单位年的信息描述了1600多台空气处理机组和冷凝器的可靠性和维护活动。对该设备的分析揭示了设备设计固有的故障以及可能受预防性维护影响的故障。设备维护和故障率之间的这些迷人且往往违反直觉的关系可能会改变以可靠性为中心的维护的应用。引用:2018年德克萨斯州休斯顿年会，技术论文

This paper presents a slice of an enormous facility equipment database containing failure and maintenance information for more than 100,000 power, mechanical, and electronic components. Motivated by a vested interest in the resilience of critical infrastructure, the U.S. Army Corps of Engineers collected the data. Heating, ventilating, and air-conditioning (HVAC) equipment is well represented in the database—some 13,000 unit-years of information describe the reliability and maintenance activity of over 1600 air-handling units and condensers. The analysis of this equipment sheds light on fail- ures that are inherent to the design of equipment and those that can be influenced by preventative maintenance. These fascinating and often counterintuitive relationships between equipment maintenance and failure rates may change the application of reliability-centered maintenance.
