This paper aims to investigate the impact of spare parts management on system reliability in complex equipment systems, primarily focusing on two factors: the system's continuous operational duration and the total cost associated with spare parts storage. By establishing a multi-objective optimization model, we have identified an optimal spare parts storage strategy that strikes a balance between the total cost and the system's continuous operational duration. The experimental results indicate that, within the assumed 3-year effective operational cycle of the complex equipment system, when equipping it with 2, 2, and 3 spare parts for the gyroscope, accelerometer, and servo motor respectively, the system's longest continuous operating duration is 37,300 hours, and the minimum cost is 84,000 RMB. Compared to the single-objective optimization model, this model not only reduces the total cost but also ensures that the system will not be interrupted due to spare parts shortages within its normal lifecycle. This study provides valuable insights and optimization methods for improving the reliability of complex systems. © 2023 IEEE.

This paper models a platooning system consisting of trucks and a third-party service provider (TPSP), which performs platoon coordination, distributes the platooning profit in platoons, and charges trucks in exchange for the services. Government subsidies used to incentivize platooning are also considered. We propose a pricing rule for the TPSP, which keeps part of the platooning profit including the subsidy each time a platoon is formed. In addition, a platoon coordination solution based on the distributed model predictive control (MPC) is proposed, in which the pricing rule under government subsidies is integrated. We perform a realistic simulation over the Swedish road network to evaluate the impact of the pricing rule and subsidies on the achieved profits and fuel savings. Our results show that subsidies are an effective mean to boost fuel savings from platooning. Moreover, the simulation study indicates that high pricing corresponds to a low platooning rate of the system, as trucks' incentives for platooning decrease. © 2023 The Authors.

With the increasing complexity and high reliability requirements of aircraft, researching more accurate anomaly detection methods and real-time monitoring of aircraft status is of great significance for ensuring equipment safety. This paper proposes a method based on multivariate LSTM and residual testing for anomaly detection in high-dimensional complex data. Firstly, by utilizing maximum mutual information to analyze the correlation of multidimensional data, a multivariate LSTM model is established based on high correlation parameters to predict the parameters. Then, combined with the idea of statistical hypothesis testing, test the statistical distribution of residuals on the training data of the prediction model using Kolmogorov-Smirnov method, and the dynamic threshold for anomaly detection is obtained through significance testing. Finally, real-time calculation of residuals between online monitoring data and predicted values is calculated, and anomaly detection is achieved by comparing the residual with threshold. The method proposed in this paper exhibits excellent anomaly detection performance on real flight data of aircraft. © 2023 IEEE.

This paper investigates the finite-time stabilization of a class of Markov jump systems (MJSs). To regulate the limited network resource, a probabilistic event-triggered mechanism (PETM) is initially proposed. Based on the output of PETM, mode-dependent state feedback controllers are designed to obtain the closed-loop system (CLS). A set of novel Lyapunov functional are created to analyze the finite-time stability of the CLS. Afterward, the design algorithm is established to calculate the controller gains. Finally, simulations are provided to verify the proposed results. © 2022 IEEE.

The main objective of this paper is to develop a distributed sensor fault detection (FD) approach for sensor networks in the presence of noise and transmission time of information exchange. To be specific, the approach optimizes the performance of FD by minimizing the detection uncertainty and the online implementation of the proposed method is in a distributed and recursive manner. Finally, a numerical example is illustrated to show that the distributed approach can successfully and efficiently accomplish the FD task. © 2023 IEEE.

The evaluation of regional geological hazard susceptibility is of great significance to the prevention and control of geological hazard. In this paper, the "4-20"Lushan earthquake disaster area as the research area, combined with GIS and characteristics of the research area, through correlation analysis, selected 9 influencing factors as the evaluation factors. The study was conducted using a weighted information volume-logistic regression model (WI-LR). The results were classified into five sensitivity levels: very low, low, medium, high and very high. The results show that the landslide prone areas in Lushan County are concentrated in the area below the middle of the county seat, mostly near rivers, faults and areas with peak acceleration greater than 0.4. Among them, WI-LR model (AUC=0.918) > deterministic factor model (CF =0.908) > weighted information quantity model (WI) (AUC=0.896) > information quantity model I (AUC=0.853) > information quantity logistic regression model I-LR (AUC=0.799). It indicates that WI-LR model has high evaluation accuracy. © 2023 IEEE.

As brain-computer interface (BCI) technology continues to advance in various fields, it has become one of the possible solutions for patients with motor dysfunction who have healthy thinking ability to regain motor ability. The vigorous development of deep learning (DL) provides it with a possible tool to analyze electroencephalogram (EEG) signals. Through analyzing and categorizing EEG signals associated with motor imagery (MI), the system can effectively perceive the patient's motor intentions. Currently, Convolutional Neural Networks (CNN) have exhibited exceptional performance in a variety of fields, including computer vision (CV) and natural language processing (NLP). However, the brain structure has rich spatial information, which was not fully utilized by CNN for MI-EEG signal analysis in the past. This paper introduces SP-CNN, a convolutional neural network that incorporates spatial information from the brain, to address the classification challenge of MI-EEG signals. The experimental findings indicate that this method exhibits stable and robust performance across diverse subjects. © 2023 SPIE.
