In the smart manufacturing paradigm enabled by Industry 4.0, predictive analytics leverages varied data sources, models, and algorithms to forecast potential future events such as equipment failures, downtime, or demand deviations. Effective predictive analytics deploys reliable models that provide accurate predictions in real time. Predictive maintenance and equipment health monitoring, demand and capacity forecasting, and production scheduling are essential applications for maintaining a competitive edge. Addressing these three applications forms the key contribution of predictive analytics, successfully implemented in multiple industrial case studies. The described approach capitalizes on predictive patterns embedded in process data, emphasizing data-driven process modeling for interpretable, physics-aware representations; careful selection from machine learning and statistical algorithms suitable for small- to medium-sized data sets; and well-defined protocols for rigorous model validation and evaluation.
Data-supported predictive maintenance, encompassing equipment health monitoring, offers striking potential for optimizing the reliability and availability of manufacturing assets. Reliability, quantifying the performance and risk of failure, can be enhanced by reducing the mean time between failures (MTBF) through predictive maintenance—deploying maintenance actions based on predictions of remaining useful life (RUL)—or by improving the mean time to repair (MTTR) through appropriate decision support during machine breakdowns. Analysis of past failure events helps identify failure modes and determine which monitored signals best predict each mode. With such monitoring signals in place, suitable approaches—ranging from threshold-based alerts to sophisticated predictive models—enable timely predictions of forthcoming failures, allowing the organization to act before disastrous ruptures occur. Such predictive maintenance decision support thus bolsters reliability by informing either RUL-based maintenance actions or recovery strategies.
