In particular, the casting industry faces significant obstacles, such as limited quality data acquisition for quantifying tacit knowledge and insufficient adoption of smart manufacturing technologies. As a potential remedy, this study demonstrates the application of smart manufacturing technologies for predicting the quality of reclaimed sand, specifically tailored for the sand casting industry. The developed strategy integrates: 1) detailed measurements of the environmental conditions in the sand reclamation process, and 2) a deep-learning-based model for predicting the loss on ignition (LOI) of reclaimed sand as a quality measure. The model is constructed using feature extraction from time-series data and Bayesian neural networks to predict LOI with quantified uncertainty. We propose a normality score-based reclaimed sand management strategy, which was evaluated over one and a half years of production conditions and reclaimed sand quality monitoring experiments. The demonstration case exhibits an average accuracy of 96.83 % in detecting problematic sand quality. Notably, the method significantly improved failure detection accuracy, increasing test data results from 38.34 % without uncertainty consideration to 72.5 % when uncertainty was incorporated. The proposed approach has the potential to advance the casting industry by enabling quality-data-driven management of the sand reclamation process, ultimately reducing defect rates and optimizing production costs.</div></div>","PeriodicalId":16227,"journal":{"name":"Journal of Manufacturing Systems","volume":"79 ","pages":"Pages 584-597"},"PeriodicalIF":12.2,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143437240","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}

This is known as the Assembly Line Balancing Problem, an NP-hard optimization problem. Automatic solvers for this problem have been studied for decades but have not been widely adopted in the industry, resulting in a theory-practice gap. The typical automation approach assumes that all constraints and objectives are known and can be statically defined ahead of time such that solvers with a precisely defined objective function can take a fully specified problem instance as input and produce a (near) optimal solution as output. In some industries, meeting these assumptions is particularly challenging because of properties such as mixed-model production with high model variance, multi-manned stations, large task graphs, etc. This paper explains why, in certain industries, such as automotive end assembly, complete automation is likely infeasible in practice due to challenges in modeling the problem, collecting data, and specifying the objective function. Manual intervention by an engineer as a decision-maker is therefore unavoidable. We argue that maximizing automation, by helping the decision-maker be as effective as possible, requires a decision support system (DSS) that supports an interactive and iterative workflow, thereby enabling assisted planning. Furthermore, we identify solver features that become relevant in the DSS context, thus making the case that focusing on standalone solvers, and treating the integration into a DSS as an implementation detail, is not a viable option. We conclude that decision support systems play a central role in closing the theory-practice gap.</div></div>","PeriodicalId":16227,"journal":{"name":"Journal of Manufacturing Systems","volume":"79 ","pages":"Pages 515-527"},"PeriodicalIF":12.2,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143420439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, HCSM technologies have been struggling to reach their full potential due to the lack of digital literacy among manufacturing workers, particularly in real-time machine monitoring. Current monitoring systems with rigid interfaces limit the operators to handle Industrial Internet of Things (IIoT) systems to directly query manufacturing data for further analysis without external technical support. To address such bottlenecks, we propose ChatCNC, a conversational machine monitoring framework that integrates Large Language Models (LLMs) to enable natural language-driven interactions with real-time Computer Numerical Control (CNC) machine data. Leveraging LLM-based multi-agent collaboration and Retrieval-Augmented Generation (RAG), ChatCNC interactively retrieves data from real-time IIoT database while also supporting context-aware responses based on the collected data, which reduces reliance on technical support from software engineers. As ChatCNC allows rapid adaptation of LLM Application Programming Interfaces (APIs) via prompting techniques, its performance is evaluated across multiple versions, each combining different LLMs and prompts, using various types of questions. Notably, our framework demonstrates its reliability in human-data interaction for industrial applications, achieving 93.3% accuracy in responding to complex queries that require advanced data inference like production tracking. Furthermore, possible failure modes are thoroughly analyzed based on interaction scenarios among multiple LLM-based agents. Such results highlight the potential of the framework as a cornerstone for HCSM.</div></div>","PeriodicalId":16227,"journal":{"name":"Journal of Manufacturing Systems","volume":"79 ","pages":"Pages 504-514"},"PeriodicalIF":12.2,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143420438","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}

This paper establishes a dynamic multi-objective flexible PCB shop scheduling model to address the challenges above.

The condition monitoring technique based on graph theory can provide an overall reliability assessment and thus guide DT model updating.

To tackle this limitation, a novel graph construction paradigm based on the mechanism of performance degradation and fault propagation is developed in this study. On this basis, unsupervised learning is further combined to form a dynamic spatio-temporal graph based condition monitoring framework for DT consistency retention. Specifically, the spatial dependencies of multi-sensors are quantified based on the evolution of the fault-related frequency band, and then multidomain features are assigned to each graph node. After that, the spatio-temporal graph set is fed to a dual-decoder graph autoencoder to extract the essential features of normal conditions, where a domain adaptation module is introduced to eliminate environmental effects. Hypothesis testing is conducted at last to inspect the machine state over time and make the final decision.

Scheduling flexible job shops in such a production environment holds practical value. However, due to the high complexity of certain jobs, the transfer of jobs between different factories are often required in practical production to balance machine load rates. Accordingly, this study addresses the distributed heterogeneous assembly flexible job shop scheduling problem with transfers, aiming to minimize both the makespan and total energy consumption. First, a multi-objective optimization model is formulated to define the problem, wherein knowledge of factory assignment and processing sequence for operations is summarized. Subsequently, given the complexity of this problem, a Q-learning-based improved multi-objective genetic algorithm (QL-IMOGA) is proposed as an effective approach. Within the proposed algorithm, a hybrid population initialization method is designed, considering factory load balancing and the earliest product completion time, to generate a high-quality initial population. Furthermore, two types of crossover operators, four types of mutation operators, and six objective-oriented neighborhood search operators are devised to enhance the algorithm’s exploration and exploitation capabilities. Q-learning is employed for adaptive adjustment of key parameters to improve both convergence speed and solution quality. The effectiveness of the proposed population initialization method and neighborhood search operators is validated through 15 test cases. The results demonstrate that the proposed algorithm significantly outperformed four advanced meta-heuristic algorithms. Furthermore, it is observed that the solution employing the job transfer strategy led to an average reduction of 7.5 % in makespan, a 3.9 % decrease in total energy consumption, and an 8.4 % improvement in factory load rates compared to the solution using the job no-transfer strategy.</div></div>","PeriodicalId":16227,"journal":{"name":"Journal of Manufacturing Systems","volume":"79 ","pages":"Pages 398-418"},"PeriodicalIF":12.2,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143350487","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}
