Since the control protocol directly affects control performance, there is definitely a close relationship between the consensus performance of the agents and the control protocols. To this end, a nonaffine nonlinear relationship of consensus error regarding the control protocol is established. Then, to deal with the unknown nonlinearity, a dynamic linear input–output relationship between two triggered batches is established by an event-triggering linearly parametric data model (ET-LPDM) where a triggering mechanism is designed along the iteration axis. Furthermore, both the event-triggered control law and the event-triggered parameter estimation law are derived from two objective functions, respectively, by using the ET-LPDM, where the values at nontriggering iteration remain unchanged from the latest triggering iteration to reduce the consumption of system resources. The proposed ET-DirDDILC does not rely on the MAS dynamical formulation. The convergence is proved and simulation study verifies the effectiveness of the presented ET-DirDDILC for MASs with both fixed and switching topologies.","PeriodicalId":48915,"journal":{"name":"IEEE Transactions on Systems Man Cybernetics-Systems","volume":"55 10","pages":"7499-7509"},"PeriodicalIF":8.7,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145090116","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}

However, despite the prevalence of job-to-product assembly process in industrial fields, the investigation of distributed assembly welding shop scheduling problem (DAWSP) remains unexplored. Meanwhile, given the energy-intensive characteristic of welding operations, addressing energy consumption in welding shop is crucial for achieving environmental sustainability. Thus, this study investigates the energy-efficient DAWSP (EDAWSP), focusing on minimizing total energy consumption (TEC) and makespan. The proposed approaches include a mixed integer linear programming (MILP) model and a knowledge-guided co-evolutionary algorithm (KCEA). In KCEA, a knowledge coefficient is defined to build a bridge that connects the welding part and assembly part. By incorporating knowledge coefficient and weight-sum approach, an effective initialization strategy is proposed for producing a superior initial population. To effectively complete evolutionary process, a co-evolutionary operator is devised based on bi-population strategy. To improve KCEA’s exploitation capability, a local search is developed within the variable neighborhood search (VNS) framework, utilizing six critical-path-based neighborhood structures. Besides, an energy-saving strategy is presented to further minimize TEC without increasing makespan. Finally, a series of comparison experiments are executed. The experimental results illustrate that all improved components of KCEA contribute to its performance, and KCEA outperforms other six optimization algorithms in solving EDAWSP.","PeriodicalId":48915,"journal":{"name":"IEEE Transactions on Systems Man Cybernetics-Systems","volume":"55 10","pages":"6937-6950"},"PeriodicalIF":8.7,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145100508","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, a flexible job shop lot-splitting scheduling model with the optimization objectives of total energy consumption, makespan, and total processing cost is formulated. Second, a hybrid approach of the KLSM and the IMOEA is designed to solve the model. The solution space of the problem is fully explored based on the moth-flame operator. Co-evolutionary operators are performed to promote information interaction among populations, hence both the population diversity and the convergence effect of the algorithm are improved. Moreover, a post-adjustment strategy based on adjacent processes is developed to reduce unnecessary fixture changes. Finally, extended experiments between some KLSM-based well-known and novel algorithms, including the proposed IMOEA, MOEA/D, NSGA-II, MOPSO, SGECF, SCEA, and SLMEA are conducted in benchmark problems and a real-world case of machine tool plant. The results show that the proposed method outperforms its competitors on co-optimization of lot-splitting, machine allocation, operation sequencing, and fixture assignment of the <inline-formula> <tex-math>$gamma $ </tex-math></inline-formula>-shop scheduling, which can effectively reduce total energy consumption, makespan, and total processing cost.","PeriodicalId":48915,"journal":{"name":"IEEE Transactions on Systems Man Cybernetics-Systems","volume":"55 10","pages":"6901-6912"},"PeriodicalIF":8.7,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145100290","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}

To achieve this, the convergence coefficients are designed to be piecewise varying, and the end-effector task is divided into two phases. In the initial phase, only the end-effector position task is considered and the fixed coefficient convergence method is adopted, which can take into consideration both end-effector task and secondary task optimization. In the second phase, the end-effector position and orientation are taken into account concurrently, and time-varying coefficients are used for end-effector task. The convergence coefficients are time varying to enhance the convergence speed, particularly when the errors are small in the later phase of task planning. This can ensure the optimization of secondary tasks when the manipulator is insufficient-redundant, and accomplish the end-effector task planning in a relatively fast speed. Finally, experiments are conducted to demonstrate the effectiveness of the proposed PVDO method in obstacle avoidance and joint limits avoidance.","PeriodicalId":48915,"journal":{"name":"IEEE Transactions on Systems Man Cybernetics-Systems","volume":"55 10","pages":"6964-6974"},"PeriodicalIF":8.7,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145100480","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}
