I. Introduction
Within Industrie 4.0, Predictive Maintenance (PdM) is considered to be one of the most promising innovations. By embedding smart, connected technology within machines or production sites, it is possible to monitor the health of a system through ongoing measurements, apply analytics, predict its future deterioration and remaining useful life (RUL) [1]. Over 80% of surveyed manufacturing companies are aware of the enormous upside potential of PdM and are currently elaborating their opportunities intensively [2]. The digitalization and its increasing flood of data confronts manufacturing companies – especially Small and Mediumsized Enterprises (SMEs) – with strategic challenges. Despite of being assessed as highly relevant in the next two to five years, the capability and applicability of PdM for industrial machinery today is still considered low [3].
