In this paper, a new exponential weighted moving average data distillation method is proposed for the design of a semi-supervised soft sensor for industrial cyber-physical systems. Through the introduction of a data distillation method, additional unlabeled data samples can be naturally incorporated for semi-supervised soft sensor modeling, without increasing the number of training data samples, thus the computational complexity of the model can be well controlled. Particularly, a new condensed labeled dataset is formulated, which contains information from both original labeled and unlabeled datasets. Another benefit of data distillation lies in its potential solution for the problem of timeline alignment between input and output variables in soft sensor modeling, which has been ignored in most current works. Two industrial case studies are provided for performance evaluation of the developed method, based on which both feasibility and effectiveness are confirmed.","PeriodicalId":100640,"journal":{"name":"IEEE Transactions on Industrial Cyber-Physical Systems","volume":"4 ","pages":"129-136"},"PeriodicalIF":0.0,"publicationDate":"2026-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147299688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, AI agents remain weak in plan verification and are vulnerable to perception errors caused by dynamic environments and inconsistent Industrial Internet of Things data. These limitations critically undermine the effectiveness of AI agent planning in complex production environments. To address the limitations, this study proposes a digital twin-aided AI (DTAI) agent-based production system, in which digital twins provide a causal data provisioning and simulation layer to support situation awareness and decision validation. A causally consistent symbiotic simulation approach is further introduced to align simulation results with actual production processes while reducing monitoring overhead. Controlled experiments show that the proposed approach achieves a higher rate of optimal scheduling while reducing monitoring overhead with production increase, and lowers computational cost compared with alternative digital twin synchronization designs. A large-scale aerospace manufacturing case study demonstrates that DTAI-based scheduling with consistent symbiotic simulation can largely reduce rescheduling rate by identifying and eliminating most resource conflicts, which further improves multi-objective production efficiency, including equipment usage, makespan, etc. These results indicate that the proposed framework provides a practical and verifiable solution for deploying AI agent-based intelligent manufacturing systems.","PeriodicalId":100640,"journal":{"name":"IEEE Transactions on Industrial Cyber-Physical Systems","volume":"4 ","pages":"137-149"},"PeriodicalIF":0.0,"publicationDate":"2026-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147362465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this need, we propose a data-driven decision-making framework for IQI, grounded in generative artificial intelligence and deep reinforcement learning. This study focuses on the component assembly process, a critical stage in manufacturing. We first develop a generative AI-driven daptive framework that constructs a high-fidelity assembly line. This environment realistically incorporates stochastic factors such as component defective rates, inspection mechanisms, and handling strategies for non-conforming products. To provide a rigorous foundation for algorithmic optimization, we formally model this dynamic ecosystem as a Markov Decision Process (MDP), defining its state space and probabilistic transition rules. We then introduce the integrated Rainbow Deep Q-Network (Rainbow DQN) algorithm to solve the resulting multi-step sequential decision-making problem. Our approach leverages the synergistic advantages of multiple DQN extensions to master dynamic quality control policies. Extensive experimental evaluations, including ablation studies and comparisons against benchmark algorithms such as traditional Monte Carlo methods, confirm the superiority of our proposed framework.

Consequently, the aeronautical assembly industry is confronted with substantial new challenges in fulfilling these demands. This work analyzes aircraft final assembly line scheduling including three critical issues: proxy-based energy-aware scheduling, worker assignment, and process planning. Specifically, it addresses an integrated assembly line problem focused on complete assembly tasks, with optimization criteria aimed at minimizing total delay and alleviating workload imbalance along the assembly line. To formalize the practical optimization problem, a multi-objective nonlinear mathematical model is developed. Then, an improved multi-objective genetic algorithm is proposed, which directs the convergence of the Pareto front by incorporating an enhanced hierarchical clustering mechanism that incorporates both fitness and chromosome dimensions. An adaptive factor and an objective function are introduced to increase the convergence speed of the algorithm to align with real production needs. Finally, through independent experiments, the proposed algorithm is rigorously compared to other multi-objective algorithms, demonstrating that the proposed algorithm achieves respective improvements of 4.0% and 8.5% in the inverted generational distance (IGD) metric and 10.6% and 18.1% in the hypervolume (HV) metric, as compared to two state-of-the-art algorithms.","PeriodicalId":100640,"journal":{"name":"IEEE Transactions on Industrial Cyber-Physical Systems","volume":"4 ","pages":"82-93"},"PeriodicalIF":0.0,"publicationDate":"2026-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146175758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper investigates finite-time event-triggered control for switched affine time-delay CPSs under average dwell-time constraints, aiming to resolve controller-system mismatches induced by switching during trigger intervals and to allocate communication resources efficiently. Firstly, an event-triggered mechanism (ETM) incorporating multiple parameter matrices is developed. Unlike conventional designs, the proposed framework accommodates subsystem switching within inter-trigger intervals, ensuring stability despite plant-controller asynchrony. Under the ETM, the co-design of a delay-compensating switching signal and an adaptive state feedback controller through parameter-dependent matrix formulations, are presented. Furthermore, leveraging Lyapunov-Krasovskii functional theory, sufficient stability criteria are established through linear matrix inequalities (LMIs), ensuring finite-time stability (FTS), finite-time boundedness (FTB), and predefined disturbance attenuation levels under average dwell-time restrictions. The Zeno-free execution of triggering sequences are rigorously verified. Experimental results on a DC-DC boost converter verify the correctness of the proposed method, demonstrating that the considered system achieves finite-time convergence even in the presence of affine nonlinearities and external disturbances.","PeriodicalId":100640,"journal":{"name":"IEEE Transactions on Industrial Cyber-Physical Systems","volume":"4 ","pages":"94-105"},"PeriodicalIF":0.0,"publicationDate":"2026-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146175702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
