The parallel row ordering problem is an important component of facility layout problems. To address the limitations of current parallel row layout research, which often overlooks the presence of obstacles and fixed material handling points, this study proposes a three-dimensional (3D) parallel row ordering problem that considers adaptive material handling points and obstacles based on the actual conditions of manufacturing workshops. This problem focuses on determining the exact final positions of material handling points in 3D space. Subsequently, we developed a mixed-integer linear programming model to minimise material handling costs. For small-scale instances, a commercial solver was used to determine the exact solutions. In contrast, for large-scale problems where commercial solvers exhibit limited performance, a two-stage method was proposed. In the first stage, an improved genetic algorithm combined with a tabu search was employed to identify a high-quality facility sequence. In the second stage, a commercial solver was utilised to optimise the specific locations of material handling points to achieve lower material handling costs. The correctness of the proposed model and two-stage method was validated through benchmark instances. Then, the versatility of the proposed algorithm was demonstrated by comparing the obtained computational results of solving basic parallel row ordering problem instances with those of various algorithms. Finally, two actual cases were used to confirm the practical applicability of the algorithm.</div></div>","PeriodicalId":50941,"journal":{"name":"Advanced Engineering Informatics","volume":"68 ","pages":"Article 103636"},"PeriodicalIF":8.0,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144588535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most methods typically assume access to multiple source domain data, and the label types of the source and target domain data are consistent. This is difficult to address in practical engineering problems because of the probabilistic nature and uncertainty of fault occurrences, which may arise from only a single source domain data being available and the emergence of new data with some unknown fault types, defining it as a Single-source Open Domain Generalization Fault Diagnosis (SODGFD) task. To address the important and challenging practical issues, this paper proposes an Adaptive Single-source Open Domain Generalization Network (ASODGN). Firstly, a physically embedded autoencoder (PEA) is proposed, trained using single-source domain data. The original data is processed through a novel wavelet packet energy encoder, embedding wavelet packet energy into a low-dimensional feature space consistent with the data feature dimensions, and dynamically adjusting the wavelet packet energy and data features using a dynamic weight mechanism. Secondly, a sparse regularized activation function (SRA) with strong feature constraint capability is adopted to form a classifier, achieving data classification functionality. Finally, an Adaptive Open-set Feature Separation algorithm (AOFS) is developed, which comprehensively considers both the data information and positional information and utilizes a hard threshold to partition open-set data in the test set.

This paper proposes a Cognitive-Adaptive Framework for Human-AI Decision Systems, operationalized through a layered heterogeneous network system that employs a dual-decomposition structure to integrate user feedback, contextual variables, and LLM-generated uncertainty cues. The framework decomposes uncertainty processing into three stages—Qualification, Delivery, and Adaptation—and analyzes human responses through multi-level statistical, mediation, and causal inference. Empirical results from a controlled experiment show that the direction of uncertainty (certainty vs. uncertainty) exerts the strongest influence on decision efficiency and trust; ambiguity, more than information volume, mediates trust and accuracy; and task-required expertise modulates users’ preferences for different uncertainty formats. The proposed system demonstrates high computational efficiency, structural robustness, and behavioral interpretability. These findings offer practical strategies for user-aligned LLM uncertainty communication and lay a foundation for adaptive, context-sensitive XAI systems.</div></div>","PeriodicalId":50941,"journal":{"name":"Advanced Engineering Informatics","volume":"68 ","pages":"Article 103634"},"PeriodicalIF":8.0,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144579662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study is to improve the automatic classification accuracy of EWIS safety risk levels using narrative reports, addressing challenges such as data sparsity and semantic complexity. To this end, this study proposes an innovative model fusion strategy to construct a robust and accurate EWIS safety risk level classification model. Specifically, Multidimensional Easy Data Augmentation (Multi-EDA) enhances data diversity and coverage. Word2Vec is then employed to transform the preprocessed text into dense semantic vectors. Subsequently, a Bidirectional Long Short-Term Memory Neural Network with a Multi-Head Attention Mechanism (MHATT-BiLSTM) captures both bidirectional dependencies and long-range semantic relationships within EWIS texts. The model is evaluated using seven evaluation metrics: Accuracy, Precision, Recall, F1-score, Macro F1, Micro F1, and Weighted F1. Experimental results demonstrate that the proposed strategy consistently outperforms various benchmark and state-of-the-art models across all metrics. This research contributes a domain-adapted risk classification framework tailored to the linguistic and structural features of EWIS narratives, which enhances the modeling of professional aviation texts.

To address the above challenge, this paper proposes an integrated hierarchical control strategy to enhance overall vehicle stability and safety, utilizing a fast iterative optimization solution that incorporates both state and control constraints. At the high level, a nonlinear model predictive controller (NMPC) is designed to meet multiple safety control requirements, employing tire slip ratios solved as virtual control inputs. The oriented prediction model captures road unevenness, tire combined-slip characteristics, and dynamic loads. To enhance computational efficiency, a Pontryagin’s Minimum Principle (PMP)-based fast-solving algorithm is employed, reformulating the nonlinear optimization problem into a two-point boundary value problem and addressing original hard constraints through terminal covariate adjustments. At the low level, another predictive controller is implemented to regulate motor torques, ensuring accurate tracking of the desired tire slip ratios. Hardware-in-the-loop test results demonstrate improved overall vehicle stability under challenging driving conditions, with the millisecond-level solution effectively achieving more constrained and satisfactory performance. Additionally, the designed PMP-based fast solution method achieves a nearly 60% speedup compared to the traditional sequential quadratic programming (SQP).</div></div>","PeriodicalId":50941,"journal":{"name":"Advanced Engineering Informatics","volume":"68 ","pages":"Article 103597"},"PeriodicalIF":8.0,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144579661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
