However, existing solutions force design teams and corporations to take a primarily serial approach where manufacturing and procurement decisions are largely contingent on design, rather than being an integral part of the design process. In this work, we propose a new approach to part making where design, manufacturing, and supply chain requirements and resources can be jointly considered and optimized. We present the Generative Manufacturing compiler that accepts as input the following: (1) An engineering part requirements specification that includes quantities such as loads, domain envelope, mass, and compliance, (2) A business part requirements specification that includes production volume, cost, and lead time, (3) Contextual knowledge about the current manufacturing state such as availability of relevant manufacturing equipment, materials, and workforce, both locally and through the supply chain. Based on these factors, the compiler generates and evaluates manufacturing process alternatives and the optimal derivative designs that are implied by each process, and enables a user guided iterative exploration of the design space. As part of our initial implementation of this compiler, we demonstrate the effectiveness of our approach on examples of a cantilever beam problem and a rocket engine mount problem and showcase its utility in creating and selecting optimal solutions according to the requirements and resources.</div></div>","PeriodicalId":55219,"journal":{"name":"Computers in Industry","volume":"168 ","pages":"Article 104286"},"PeriodicalIF":8.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143738900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, there is a distinct lack of intuitive, user-friendly platforms for visualizing and interactively controlling the shape-shifting capabilities of these robots. In response to these challenges, this paper introduces an innovative digital twin (DT) system for reconfigurable soft robots set within an augmented reality (AR) environment. This system facilitates a more natural and accurate depiction of 3D soft deformations and provides an intuitive interface for simulation. We utilize a parameterized curve-driven method to dynamically adapt the DT in the AR space, ensuring smooth transitions between various 3D shape-morphing states. We identify three fundamental shape-morphing patterns – stretching, bending, and twisting – and create advanced visualization tools to precisely demonstrate these morphological changes. To enhance the real-time representation of shape-morphing, we employ sensor fusion to detect and depict the soft robot’s structural changes as parameterized curves. Our system is fully operational in an AR environment, empowering users to conduct immersive examinations and simulate reconfigurations of real-world soft robotic systems.</div></div>","PeriodicalId":55219,"journal":{"name":"Computers in Industry","volume":"168 ","pages":"Article 104285"},"PeriodicalIF":8.2,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, two mechanistic models were developed and validated using gas exit temperature data, achieving average prediction error rates of 5.6% and 5.2% for the drying and regeneration processes, respectively. These mechanistic model prediction errors were then used to train a machine learning model, reducing previous prediction errors to 1.2% and 3.7%. The models were subsequently combined into a hybrid structure and embedded within a moving horizon estimation framework to monitor the internal states of the mechanistic model in real-time. This approach meets observability requirements and provides a more robust solution than open-loop predictions, as demonstrated in the paper through studies using historical process data for both drying and regeneration operations.

Our proposed approach establishes a fault scoring metric set (FSMS) by integrating multi-similarity metrics and model gradient information. Furthermore, a selection and fusion strategy for the FSMS is designed based on the old stage generated validation datasets to obtain a fusion fault scoring metric and realize fault detection. A gradient fusion digital twin is further proposed for fault diagnosis. The method fuses time–frequency and model gradient features to distinguish different fault modes. To verify the effectiveness of the proposed method, experiments were conducted on rolling bearing datasets.

The complexity of intelligent industrial environments introduces various challenges, including vulnerabilities caused by faults that can propagate across multiple layers and heterogeneous systems. Predictive maintenance becomes more complicated due to the need for advanced monitoring across interconnected systems, and the dynamic nature of these environments demands seamless adaptation. This is essential for fostering harmony between human operators and intelligent systems in real-time. However, the increasing complexity of these environments reveals the limitations of the current HCI models, making adaptability a basic requirement. This paper carries a complete 141-paper review regarding research on HCI along with a detailed exposition of the core architecture, enabling technologies, and real-world application examples. Furthermore, it presents an innovative conceptual model for implementing an HCI system that dynamically adapts to environmental changes, user behavior, diverse user profiles, and varying accessibility needs, specifically within the context of fault detection and diagnosis systems. The proposed approach has been rigorously validated through empirical studies, demonstrating its effectiveness and practical applicability. To improve resiliency and efficiency in such a smart industrial system as is vulnerable, the interface would adapt itself to user behavior and diversity.

This paper proposes a camera-chain-based multipoint displacement measurement system for long-span beam bridges. The system primarily consists of double-head camera stations linked by artificial markers. By connecting the optical paths of the camera stations in the physical setup and compensating for motion-induced errors in the measurement model, the system can be deployed along a deformed beam to enable synchronized dynamic measurements at multiple points. Comparative field tests demonstrate that the displacement measurements obtained from this system are consistent with those from traditional methods, such as manual leveling and automated connecting pipe systems, while providing advantages in terms of dynamic monitoring and the breadth of measurement parameters. Benefiting from real-time multipoint measurement, the system captures detailed spatial deformation curves. In addition, the observed vehicle-induced evolution of bridge deflection aligns well with the recorded vehicle speed and can be used to evaluate the modal parameters of beam bridges. The proposed method and system can provide new options and better data for bridge displacement monitoring to support the accuracy and timeliness of safety warnings.</div></div>","PeriodicalId":55219,"journal":{"name":"Computers in Industry","volume":"168 ","pages":"Article 104271"},"PeriodicalIF":8.2,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143511814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
