报告摘要:
We present 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.
We develop 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.
