Existing studies usually ignore the critical role of workers in distributed manufacturing, and conventional multiobjective optimization algorithms struggle to balance convergence and solution diversity. To address these gaps, this paper develops a worker–machine–environment collaborative model for DHHFSP that simultaneously minimizes makespan, total energy consumption, and total worker cost, and proposes a hybrid multiobjective particle swarm optimization algorithm with Q-learning-driven local search (HMOPSO-QLS). The proposed approach features a hybrid framework that combines multidirectional particle swarm global search with reinforcement learning-based local search, a Pareto front oriented four directional swarm decomposition and update mechanism where three boundary exploration sub-swarms and one central exploration sub-swarm cooperatively guide particle evolution, and a two level local search scheme that integrates domain knowledge based inter-factory load balancing with Q-learning based adaptive intra-factory variable neighborhood search. Comprehensive experiments demonstrate that HMOPSO-QLS significantly outperforms classical multiobjective optimization algorithms in solving DHHFSP in terms of convergence and solution diversity. In distributed human–machine collaborative manufacturing, the proposed framework and algorithm support more effective configuration of factories, machines, and workers, providing robust schedules that are directly applicable to practical production decision-making and cross-factory coordination.</div></div>","PeriodicalId":16227,"journal":{"name":"Journal of Manufacturing Systems","volume":"85 ","pages":"Pages 1-21"},"PeriodicalIF":14.2,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145852447","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}

Additionally, several adaptive genetic operators are designed to enhance the global search capability of the algorithm.

Inspection path planning (IPP) for touch-trigger probes on coordinate measuring machines (CMMs) still suffers from heavy reliance on manual rules and poor coordination among planning stages. To address these limitations, this paper proposes a novel approach for IPP based on a hybrid planning framework, called <strong>Inspection Path Optimization via Deep Reinforcement Learning &amp; Heuristic Search (InPO-DRLHS)</strong>. InPO-DRLHS leverages hierarchical reinforcement learning (HRL) to generate collision-free paths (CFPs) while accounting for probe orientation changes, and integrates this architecture with heuristic-based optimization of measurement sequence to improve global planning efficiency. Specifically, within the HRL module: the lower-level agent employs an improved deep Q-learning approach to generate optimal CFPs under fixed probe orientations; the higher-level agent predicts optimal probe rotation positions from a voxelized scene representation, guiding orientation adjustments for the lower-level planning. Furthermore, the value function learned by the HRL module serves as a surrogate heuristic estimate within the heuristic algorithm during sequence planning, enabling path quality assessment without explicit CFP generation. Experimental results show that the proposed method achieves over 90% success rate in 3D CFP planning and reduces total measurement time by 21.7% compared to conventional approaches, indicating substantial gains in inspection efficiency.</div></div>","PeriodicalId":16227,"journal":{"name":"Journal of Manufacturing Systems","volume":"85 ","pages":"Pages 34-50"},"PeriodicalIF":14.2,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145928458","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}

Building upon this dataset, an enhanced PointNet+ + (PNP) network is employed to extract and fuse multi-source assembly features from part shape point clouds and tooling movements. These fused features are then integrated with a generation network based on the Conditional Generative Adversarial Network (CGAN) architecture, reformulating gap prediction as a conditional generation task. The innovative integration of the two networks realizes an end-to-end pipeline, from initial assembly feature extraction to final assembly gap prediction. A representative wing-box structure was employed as a case study to validate the approach. The trained model efficiently predicts gap fields directly from multi-source assembly information.
