These varying terms and frequent incompatibilities necessitate a unified approach to characterize and craft Digital Twin models. This endeavor aims not only to streamline construction processes but also to ensure the reusability and collaboration of Digital Twin models across diverse scenarios. This work proposes Digital twin model building strategy (DTBS), deriving four key processes for constructing digital twin models from the perspective of application scenarios: based on physical entities, twin service requirements, physical data, and entity requirements. Subsequently, by defining the application scenarios and employing suitable strategies, the building of digital twin models is accomplished. The DTBS serves as the core strategy for the building of digital twin models, guiding the complete construction process of digital twin models. The DTBS aims to achieve three objectives: comprehensiveness (encompassing all stages of digital twin model building), operability (with low thresholds for researchers and practitioners), and scalability (encompassing not just one scenario, but multiple domains). Additionally, through case studies, the effectiveness of the Digital twin model building strategy in practical engineering contexts is expounded upon. This strategy's strength lies in its ability to maintain scalability while also demonstrating comprehensiveness and operability.</div></div>","PeriodicalId":16227,"journal":{"name":"Journal of Manufacturing Systems","volume":"80 ","pages":"Pages 366-379"},"PeriodicalIF":12.2,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143683290","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}

Rational decision-making on the recovery options of product parts is an effective way to achieve environmental goals. Meanwhile, manual disassembly is very important in the recycling process, and the learning effect of workers has a great influence on disassembly. Therefore, a collaborative selective disassembly planning and end-of-life products recovery option decision model considering the learning effect is proposed. The objective is to minimize disassembly time, and carbon emissions and maximize disassembly profit. To obtain a high-quality disassembly scheme, an improved multi-objective genetic algorithm based on Q-learning is proposed. To improve the quality of the initial solution, a three-layer encoding strategy including disassembly sequence, disassembly decision sequence, and recovery option decision sequence is designed. Four search strategies are designed as actions for Q-learning, and the state is constructed based on population fitness. This way can enable the algorithm to dynamically adjust the optimization search strategy during the iterative process. Then, the accuracy and effectiveness of the algorithm are verified by two test cases. Next, the proposed model and algorithm are applied to a real refrigerator disassembly case. The results show that due to the learning effect, the efficiency of the disassembly can be increased by 31.66 %, the cost can be reduced by 30.44 %, and the carbon emissions can be reduced by 30.07 %.

Therefore, task allocation and scheduling, which determine who performs tasks and when they start and finish, should consider both efficiency and fatigue in human–robot collaboration. Efficiency needs to be maximized while fatigue needs to be minimized, necessitating a compromise solution to balance these conflicting objectives. Task allocation guided by multiple objectives is computationally more complex. Furthermore, the production line, with its numerous components and tasks, typically has a larger search space, especially in scenarios involving multiple humans and robots. This complexity makes it challenging for most current human–robot task allocation methods to effectively address such problems. Thus, a new task allocation and scheduling method to balance efficiency and fatigue is proposed in this paper. It reallocates initial sequential human actions to all the humans and robots, obtains locally optimal solutions by multi-heuristics search with efficiency and fatigue synergized, and a fast-converging greedy search is then employed to refine these locally optimal solutions to approach the global optimum.

This paper introduces a novel temperature sensor positioning method for thermal error compensation that leverages a digital twin framework to virtually determine ideal sensor positions and their effects on the compensation model.
