Abstract

This paper presents a comprehensive maintenance strategy for service systems by integrating condition-based maintenance (CBM) with queueing theory. The proposed strategy leverages real-time deterioration data to optimize server performance and reliability while balancing the costs of maintaining standby equipment and ordering new components. Our study develops an integrated maintenance model based on an M/M/1 queueing system, simulating performance degradation using condition monitoring data. This model determines the optimal reordering state for critical server equipment. Extensive numerical analyses validate its effectiveness, and a sensitivity analysis identifies key factors affecting cost and profitability. Key contributions include: (1) An integrated system model combining CBM and queueing theory to optimize maintenance strategies; (2) A computationally efficient Markov chain-based model that reduces complexity while maintaining accuracy; (3) Explicit formulas for performance metrics such as server availability, system reliability, and reorder lead time. The proposed model minimizes long-term average costs while maintaining high service availability and reliability, offering practical insights for improving maintenance efficiency across industries.

具有备用设备的排队系统的维护策略：使用基于状态的监测的集成方法

将基于状态的维修（CBM）与排队理论相结合，提出了一种服务系统综合维修策略。提出的策略利用实时劣化数据来优化服务器性能和可靠性，同时平衡维护备用设备和订购新组件的成本。本研究开发了一个基于M/M/1排队系统的集成维护模型，使用状态监测数据模拟性能下降。该模型确定了关键服务器设备的最优重新排序状态。广泛的数值分析验证了其有效性，敏感性分析确定了影响成本和盈利能力的关键因素。主要贡献包括：(1)建立了一个结合CBM和排队理论的维修策略优化集成系统模型；(2)基于马尔可夫链的高效计算模型，在保持准确性的同时降低了复杂性；(3)明确的性能指标公式，如服务器可用性、系统可靠性和再订货提前时间。提出的模型在保持高服务可用性和可靠性的同时，最大限度地降低了长期平均成本，为提高各行业的维护效率提供了实用的见解。

期刊介绍： Elsevier publishes Reliability Engineering & System Safety in association with the European Safety and Reliability Association and the Safety Engineering and Risk Analysis Division. The international journal is devoted to developing and applying methods to enhance the safety and reliability of complex technological systems, like nuclear power plants, chemical plants, hazardous waste facilities, space systems, offshore and maritime systems, transportation systems, constructed infrastructure, and manufacturing plants. The journal normally publishes only articles that involve the analysis of substantive problems related to the reliability of complex systems or present techniques and/or theoretical results that have a discernable relationship to the solution of such problems. An important aim is to balance academic material and practical applications.
