Fault detection and classification (FDC) is a critical technique utilized in manufacturing and engineering sectors for identifying and categorizing anomalies or faults in systems, processes, or machinery. The primary objective of FDC is to pinpoint deviations from standard operational parameters, determine the underlying causes of these faults, and systematically classify them according to specific characteristics or attributes. This process helps in maintaining operational efficiency and preventing potential failures.

Fault detection and classification (FDC) systems encompass three main components such as software, hardware, and services. The software component consists of sophisticated programs that manage data processing, analysis, and control of systems. This software is adept at identifying a variety of fault types such as multidimensional faults, process variability, surface defects, and contamination issues, employing advanced technologies such as sensor data analysis, statistical methods, and machine learning algorithms. Hardware typically includes the sensors and computing devices necessary to collect and process data. The services component involves the support and maintenance needed to implement and optimize these systems. Together, these elements are applied across diverse industries, including manufacturing and packaging, serving sectors such as automotive, electronics and semiconductors, metals and machinery, food and packaging, and pharmaceuticals.

The fault detection and classification market consists of revenues earned by entities by providing services such as anomaly detection, root cause analysis, real-time monitoring, and performance optimization, as well as related services.
