In this paper, the failure mechanism of electronic equipment was analysed. Aiming at the limitation of traditional maintenance modes, modern maintenance strategy was put forward on the basis of reliability-centered maintenance (RCM) combined with condition-based maintenance (CBM)and maintenance efficiency review (MER). A maintenance management information system was constructed for electronic equipment for the purpose of failure analysis, reliability evaluation, and maintenance decisions such as time, mode, and plan. The best maintenance time could be predicted with failure analysis and reliability evaluation, which was mainly influenced by environmental stress. Suitable maintenance modes should be determined from equipment importance, failure aftereffect, maintenance condition, and economical power so as to ensure equipment reliability and decrease the requirement of the maintenance source. 相似文献

设备可靠性是影响供应不确定的重要因素。为了研究企业内部的维修策略对整条供应链的运营策略产生的具体影响,在考虑设备维修的情况下,针对单个制造商和单个零售商构成的二级供应链,运用Stackelberg博弈的方法研究制造商的最优维修策略和定价策略以及零售商的最优订货量。研究结果表明,制造商的预防性维修次数存在上限且最大维修次数与设备可靠性无关;预防性维修策略有助于提高制造商的产量,降低产品的批发价格,但制造商的最优产出量不会达到企业的最大产能;收益共享契约能够实现供应链的协调;制造商在任何情形下都具有提高设备可靠性的动机,但零售商只会在市场规模较大时才存在为制造商提供设备改造资金的动机。 相似文献

基于可靠度限制的周期性预防维护模型研究 总被引:3,自引:0,他引:3
实施周期性的预防维护可以减缓设备的老化速度,进而增加设备的使用寿命.考虑设备经维护后会改善的情况.提出并构建了一个改善因子模型,以此描述设备维护改善的效果,该改善因子模型综合考虑了预防维护成本、设备年龄以及维护过程学习效应等因素影响.在改善因子模型基础上,基于无限时间域的概念,构建了包含预防维护成本、最小修复成本、置换成本等在内的成本函数.在可靠度限制下,推导出了单位时间成本函数和最佳维护时间间隔的计算模型,给出了计算最佳参数的流程.最后,进行了实例分析. 相似文献

为同时保证设备承租方对租赁设备的可用度,以及优化设备出租方的设备维护成本,提出了基于故障状态的定周期检测的多维护方式策略。首先,对租赁设备进行定周期检测,基于设备故障率来选择相应的维护策略,采取役龄回退的方式描述采取不同的维护策略后设备状态的恢复情况。其次,综合考虑周期维护成本、小修成本、惩罚成本和租赁延迟成本,建立了以出租方成本最低为目标的多维护策略优化模型。通过数学建模和数理统计方法,利用MATLAB仿真进行算例分析,将其与定周期单一预防性维护策略进行对比,证明了对租赁设备进行定周期多策略维护,其维护效果较单一预防性维护有较大的提升。 相似文献

An equipment maintenance system is naturally a complex dynamical system. The effective mamanagement must be based on the knowledge of the system's intrinsic dynamics. And the strueture of the maintenance system determines its behavior. This paper analyzes the basic structures and elements of a maintenance system for complex multi-components equipment. The maintenance system is considered as a dynamic system whose behavior is influenced by its structure's feedback and interaction, and the system's available resources. Building the dynamical model with Simulink, we show some results about the maintenance system's nonlinear dynamics, ods. The model can be used for understanding and which operational adjustments of maintenance which are never given by stochastic process methdetermining maintenance system behavior, towards n of maintenance requirements and timely supply of maintenance resources can be made in a more informed way. 相似文献
