Safety and reliability are two critical factors of modern Cyber-Physical Systems (CPS). However, the increasing structural and behavioral complexity of modern automation systems significantly increases the possibility of system errors and failures, which can easily lead to economic loss or even hazardous events. Anomaly Detection (AD) techniques pr...

The concepts of Software-Defined Manufacturing (SDM) and Digital Twins emphasize the current trend in production system development. These systems are characterized by frequent software updates to address adjustable production processes and higher system flexibility. These software-intensive systems are safety-critical and require a thorough reliab...

Errors and failures occur inevitably in modern Cyber-Physical Systems (CPS) due to their structural variability and internal heterogeneity. This can cause economic losses or even hazardous accidents. Currently, deep learning-based anomaly detection methods, e.g., Transformer or LSTM-based detectors, have shown tremendous results in terms of anomaly...

Due to the increasing behavioral and structural complexity of robots, it is challenging to predict the execution outcome after error detection. Anomaly detection methods can help detect errors and prevent potential failures. However, not every fault leads to a failure due to the system's fault tolerance or unintended error masking. In practical app...

Industrial cyber-physical systems (ICPS) are becoming more complex due to increasing behavioral and structural complexity. This increases the likelihood of faults, errors and failures. This can lead to economic losses and even hazardous events. Fault injection is an efficient method to estimate the potential risk of safety-critical ICPS. In this pa...

In modern and complex production systems, the focus is shifted toward the software part. Software-Defined Manufacturing (SDM) and Cyber-Physical Production Systems (CPPS) characterize this trend. SDM and CPPS enable the concept of adaptive, flexible, and self-configuring production systems. These software-intensive robotic systems are safety- criti...
