Predictive Maintenance in a Digital Factory Shop-Floor: Data Mining on Historical and Operational Data Coming from Manufacturers’ Information Systems

Predictive maintenance is regarded by many as a key factor in Industrial Internet of Things (IIoT) and the development of “smart” factories. With the growing use of sensors and embedded computing systems, the term predictive maintenance is most often understood as a strategy that relies on collecting streaming sensor data and performing condition monitoring. Thus, the majority of academic papers base their research work solely on sensorial sources coming from the shop floor machinery, neglecting the knowledge already existing in legacy systems and maintenance historical logs. The UPTIME project aims to develop a unified predictive maintenance framework that incorporates information from heterogeneous data sources, both from sensor devices and legacy/operational systems. In this contribution, we share our first insights on legacy data analytics in the predictive maintenance context, and outline the tools and approaches we developed in the course of the project. Experimental work has been conducted using real world datasets deriving from an actual manufacturing facility in the White Goods/Home Appliances sector. The results provide significant knowledge about the manufacturing processes and show the potential of the proposed methodology.
