Maintenance is one of the core technical aspects on board ships, which is required for the ready availability, reliability, and efficiency of machinery equipment. As machinery systems are critical for merchant ships, inadequate maintenance operations lead to serious consequences, including total loss of the vessel. The most commonly used maintenance approach on board a ship is a planned maintenance schedule (PMS). Since a PMS is highly dependent on human effort, human reliability comes into force as an important issue. However, the latest maintenance approaches, such as maintenance 4.0, focus on reducing the human workload in maintenance operations. Therefore, this study investigates the potential benefits of maintenance 4.0 in proportion to the aspects of human reliability. It examines a diesel generator maintenance operation. The shipboard operation human reliability analysis approach is utilized to conduct an empirical human reliability analysis for classic PMS, and, additionally, scenario-based maintenance 4.0 environments. Human error probability (HEP) values are calculated separately and a detailed comparison is provided. As a consequence, the overall HEP is dramatically reduced through the use of maintenance 4.0 (from 6.78E−01 to 1.17E−01).

船舶 PMS 和维修 4.0 概念下船舶辅机维修操作的人员可靠性评估

维护是船舶上的核心技术方面之一，这是机械设备随时可用、可靠性和效率所必需的。由于机械系统对商船至关重要，维护操作不当会导致严重后果，包括船舶完全损毁。船上最常用的维护方法是计划维护计划 (PMS)。由于 PMS 高度依赖于人力，因此人力可靠性成为一个重要问题。但是，最新的维护方法，例如维护 4.0，侧重于减少维护操作中的人工工作量。因此，本研究调查了维护 4.0 与人员可靠性方面的潜在好处。它检查柴油发电机维护操作。利用船上操作人员可靠性分析方法对经典 PMS 以及基于场景的维护 4.0 环境进行经验性人员可靠性分析。人为错误概率 (HEP) 值是单独计算的，并提供了详细的比较。因此，通过使用维护 4.0（从 6.78E-01 到 1.17E-01），整体 HEP 显着减少。
