摘要:

隐性故障系统通常具有非连续任务特性,但任务失效往往会导致重大经济损失。本文针对具有竞争失效机制的隐性故障系统,在考虑双重点检策略的基础上,构建了基于任务失效的视情维修决策模型。首先,通过建立系统运行状态与任务执行结果之间的关系,利用检测质量与检测结果分析系统更新情形,推导每种更新情形的发生概率;然后,采用更新报酬理论构建了以长期运行期望成本率最小化为目标的维修模型,以优化小检间隔期。最后,以继电保护系统为例验证策略和模型的有效性和适用性。研究结果表明:缺陷系统任务失效率显著影响系统的维修决策,考虑缺陷系统任务失效的维修建模能够为设备管理者提供理论参考;与单一点检策略相比,当小检成本小于阈值水平时,双重点检策略更具有成本优势,这为企业更好地规划检测策略提供理论依据和技术支撑。

Abstract:

Systems with hidden failures typically do not perform missions continuously, but mission failures in such systems can lead to substantial economic losses and severe damage. Condition-based maintenance (CBM) is an effective strategy to enhance system reliability and mitigate the risk of hidden failure. A CBM model is developed for systems subject to competing and hidden failures by incorporating mission failure behavior and a multiple inspection policy. The arrival of system missions follows a Poisson process, and the outcome of mission execution depends on the system's state. Periodic minor inspections, which are imperfect, are scheduled to detect the system’s state, while major inspections, which are perfect, are conducted only upon mission failure. Under this policy, all the possible scenarios for minor inspection preventive renewal, major inspection preventive renewal, minor inspection corrective renewal, major inspection corrective renewal, and age-based preventive renewal are analyzed, and the probabilities of each scenario occurring are derived. Consequently, the CBM model is formulated using the Renewal Reward Theorem, aiming to minimize the long-run expected cost rate, with the minor inspection interval serving as the decision variable. Finally, the effectiveness and applicability of the proposed maintenance model are validated through comparisons with two other models. The results indicate that considering mission failure due to defective systems is crucial when constructing maintenance models for multi-state systems with hidden failures, and that multiple inspection policy offers greater cost advantages than single inspection policy when the minor inspection cost is below a threshold level.

Key words: competing failures, hidden failures, mission failures, multiple inspections, condition-based maintenance
