Condition-Based Maintenance Decision-Making for Equipment

At present, condition monitoring and fault diagnosis technology and their application in engineering have been widely studied. Relatively little attention has been paid to condition-based maintenance decision-making for equipment. In this paper,based on the decision-making policy in traditional condition-based maintenance,the connotation of condition-based maintenance for equipment was defined, and its characteristics were analyzed.Working contents of condition-based maintenance for equipment were provided,which were divided into three stages. The influence factors in condition-based maintenance for equipment were analyzed. The key links of equipment maintenance contents and decision-making process were proposed. The condition-based maintenance decision-making policy presented in this paper can provide a practical reference for equipment maintenance.     

新型雷达装备系统性能可靠性评估

装备系统可靠性定量评估一直是军用产品可靠性工作的重要项目之一。提出了装备的工作性能可靠性问题是评估雷达装备系统性能可靠性的基本出发点,对雷达装备系统性能可靠性进行了定义,根据使用条件的限制,将雷达装备系统性能可靠性分为狭义工作性能可靠性和广义工作性能可靠性;通过雷达装备系统性能可靠性的分析,得出雷达装备系统性能可靠性是一个表明雷达装备工作性能可以保持多长时间的参数,是评估雷达装备效能的重要指标,提出从狭义工作性能可靠性和广义工作性能可靠性两方面评估新型雷达装备系统性能可靠性,并给出了基于狭义工作性能可靠性和广义工作性能可靠性的雷达装备系统性能可靠性评估模型,为装备维修决策、制定相关维修策略提供了科学依据。     

装备大修定价的模糊综合评判模型

利用模糊集分析理论,量化了影响装备大修定价的因素,建立了关于装备大修定价的模糊综合评判模型。通过实例对装备大修定价进行了定量计算并分析了结果,可为装备维修定价部门决策提供理论依据。
