Industry 4.0 is revolutionizing manufacturing, increasing flexibility, mass customization, quality and productivity. In today's competitive manufacturing scenario, maintenance is one of the most critical issues and companies are approaching its digital transformation from technological and management perspectives.

This article carries out a systematic literature review aimed to investigate how maintenance tasks and maintenance management strategies are changing in Industry 4.0 context, analyzing the state-of-the-art of Industry 4.0 technologies currently employed in maintenance and the resulting potential innovations in maintenance policies and manufacturing management. In addition, the most relevant trends in current maintenance policies have been investigated, such as “remote maintenance” and the attractive possibility of a “self-maintenance”. Also, the importance of human factor has been considered. The results are summarized in a comprehensive database, to provide, through concepts and empirical evidence present in literature, examples and strategies for the implementation of maintenance in Industry 4.0.

工业4.0正在彻底改变制造，提高灵活性，批量定制，质量和生产率。在当今竞争激烈的制造环境中，维护是最关键的问题之一，并且公司正在从技术和管理的角度进行数字化转型。

本文进行了系统的文献综述，旨在调查工业4.0环境中的维护任务和维护管理策略是如何变化的，分析了当前在维护中使用的最新工业4.0技术以及由此产生的潜在维护政策创新和制造管理。此外，还研究了当前维护策略中最相关的趋势，例如“远程维护”和“自我维护”的诱人可能性。而且，已经考虑了人为因素的重要性。将结果汇总在一个全面的数据库中，以通过文献中提供的概念和经验证据提供在工业4.0中实施维护的示例和策略。
