Predictive Maintenance in Industry 4.0.

In the context of Industry 4.0, the manufacturing related processes have shifted from conventional processes within one organization to collaborative processes cross different organizations, for example, product design processes, manufacturing processes, and maintenance processes across different factories and enterprises. The application of Internet of things, i.e. smart devices and sensors increases collection and availability of diverse data. Advanced technologies such as big data analytics and cloud computing offer new opportunities for effective optimization of manufacturing related processes, e.g. predictive maintenance. Predictive maintenance provides a detailed examination of the detection, location and diagnosis of faults in related machineries using various analyses. RAMI4.0 is a framework for thinking about the various efforts that constitute Industry 4.0. It spans the entire product life cycle & value stream axis, hierarchical structure axis and functional classification axis. The Industrial Data Space (now International Data Space) is a virtual data space using standards and common governance models to facilitate the secure exchange and easy linkage of data in business ecosystems. It thereby provides a basis for creating and using smart services and innovative business processes, while at the same time ensuring digital sovereignty of data owners. This paper looks at how to support predictive maintenance in the context of Industry 4.0? Especially, applying RAMI 4.0 architecture supports the predictive maintenance using FIWARE framework, which leads to deal with data exchanging among different organizations with different security requirements as well as modularizing of related functions.
