The advantage of smart manufacturing systems using cloud and RAMI 4.0

The article presents an empirical analysis of the benefits of cloud manufacturing, the need to consider the Reference Architecture Model Industry 4.0 (RAMI 4.0), and, last but not least, IoT applications. Using high-performance and complex platforms, it is possible to modernize automation, tracking, and control systems, with the condition of completing optimization systems to increase performance. The article attempts a theoretical approach to cloud systems that has implications in production systems. RAMI offers an analysis of the entire production system, a system that can be analyzed, interpreted and ensures optimal functioning through intervention. Cloud manufacturing provides an overview of the entire production system with all resources used, but also an overview of actions to optimize the production system. In order to be able to draw the most relevant conclusions in real-time, we simulated such a system using Petri nets. Petri nets are chosen because they are easier to interpret, provide real-time information, and are relatively easy to modify the system proposed for simulation, so that decisions can be made as quickly as possible without disrupting the production system. This article focuses more on the relationship between cloud manufacturing and RAMI 4.0. The advantages of this approach are computational speed and storage capacity without investing in additional configurations, user data synchronization, and data processing. The downside is that it wants to find a solution for data security, which leads to mistrust among users. The case study is applied to a module of the production system because the system is complex and can provide easy-to-interpret results for the decision-making unit.
