In the era of modernization, the term “Industry 4.0” has emerged and gained attention progressively from all relevant authorities. This term reflects the movement that gradually improves the current existing technologies and contributes to maintenance advancements in the future. The basic objective of this project is to learn and understand how computer-based technology can bring about revolutionary changes in maintenance to achieve an ideally smart industry. There are two inquiries being studied to fulfill the objective including the recognition of integration between Industry 4.0 and Cyber-Physical System (CPS) in the aspect of maintenance as well as the extent of its contribution to the future development of maintenance management. Both conception study and simulation are chosen as the research methodology for this project.
