Summary: During abnormal situations, situation awareness (SA) plays a critical role in ensuring system safety. This study focuses on short-term multi-round SA (STMR-SA) and examines the impact of anchoring effect (AE) and confirmation bias (CB) on STMR-SA errors. A novel reliability assessment method is proposed, considering the round dependencies caused by AE and CB. The method is demonstrated through a case study on the Boeing 737-8 (MAX) accident, showing that improvement measures can enhance STMR-SA reliability and system safety.

Summary: This paper proposes a method to improve the reliability of satellite communication systems by using Markov Bayesian Networks and redundancy design strategies. It introduces a Bayesian environmental importance measure that considers the unique attributes of the space environment to verify the significance of subsystems. Furthermore, a multi-objective particle swarm optimization algorithm is employed to solve the optimal number of redundancies for critical subsystems.

Summary: Compound fault diagnosis is crucial for the reliability and security of manufacturing equipment. Existing methods mainly focus on untrained compound faults, neglecting more common single faults in the test set. To address these issues, a novel broad zero-shot diagnosis method (BZSD) is proposed, which can identify both single faults and untrained compound faults, improving diagnostic accuracy.

Summary: This study aims to analyze the risk of transporting hazardous chemicals on sea-crossing bridges using a dynamic Bayesian network (DBN) model. The study found that vehicle failure has the highest impact on the transportation system and should be given more attention. Additionally, wind sensitivity to the sea-crossing bridge transportation system is significant and cannot be ignored.

Summary: This article examines the effectiveness and accuracy of threshold-based and probit-based methods in assessing domino effects. The results indicate that threshold-based methods are not suitable for quantitative assessment, and there are limitations in probit-based methods for time-dependent domino effect assessment. By utilizing site-specific structural response data and data analytics, a new improved time to failure prediction model is proposed, which demonstrates better performance compared to existing models.

Summary: Health Indicators (HIs) are widely used for health state assessments. However, obtaining the true value of HIs with physical meaning is difficult in many cases. Therefore, this study proposes a physics-informed autoencoder that combines a physics-based model with deep learning approaches to construct HIs effectively. The proposed framework redefines the conventional HI construction process by mapping sensor readings to a degradation-represented latent space using a deep learning model, and then reconstructing the sensor readings using a physics-based model.

Summary: This study investigates pedestrian behaviours and evacuation processes in both fire and non-fire conditions using Minecraft. The results demonstrate the potential of Minecraft for realistically simulating evacuation processes, as the behaviours and flow patterns of pedestrians in virtual experiments fit well with real-life experiments. The study also shows that pedestrians exhibit fire avoidance behaviours and orderly queuing during a fire emergency, resulting in faster evacuation.
