Engineering infrastructure incorporate complex systems, hazardous materials and often operated by human beings, making them prone to catastrophic accidents. Continuously improving system safety of the facilities and their operations requires a well-established asset management practices. The history of hazardous events in some domains such as process facilities suggest that many accidents have occurred due to ineffective maintenance planning strategies. Thus, to ensure an acceptable level of system safety and availability, it is essential to adopt optimal programs and practical procedures in maintenance planning engineering assets. The lessons learnt from previous accidents have helped operators, classification societies and regulators to develop viable standards and guidelines for employing quantitative methods in Operation and Maintenance (O&M) planning. The current work aims to present the existing attempts and identify the gaps, needs, and challenges of maintenance planning in engineering facilities. It then integrates the empirical and theoretical conclusions, highlighting the capabilities and drawbacks of the state-of-the-arts and explaining research opportunities and challenges. The decision-makers, operators, and managers in engineering infrastructure can exploit the present work from theoretical and practical perspectives.

工程基础设施包含复杂的系统、危险材料，并且通常由人类操作，因此容易发生灾难性事故。不断提高设施及其运营的系统安全性需要完善的资产管理实践。某些领域（例如过程设施）中的危险事件历史表明，由于维护计划策略无效而发生了许多事故。因此，为确保系统安全性和可用性达到可接受的水平，在维护规划工程资产中采用最佳程序和实用程序至关重要。从以往事故中吸取的经验教训帮助运营商、船级社和监管机构制定了可行的标准和指南，以便在运营和维护（O& M) 计划。目前的工作旨在介绍现有的尝试，并确定工程设施维护规划的差距、需求和挑战。然后，它整合了实证和理论结论，突出了最先进技术的能力和缺点，并解释了研究机遇和挑战。工程基础设施的决策者、运营商和管理人员可以从理论和实践的角度利用当前的工作。
