“…Digital twins, which have the characteristics of virtual reality mapping and interactive fusion, provide a new way of solving scheduling problems in smart manufacturing, and they can generate new scheduling plans by building production scheduling models and scheduling algorithms, as shown in Figure 4. To resolve the dynamic disturbances in the assembly process, Shen [30] established a DT-based bearing assembly planning model and proposed a task rescheduling strategy for a robotic assembly line. Villalonga [29] presented a framework for decentralized and integrated decisionmaking for re-scheduling of a cyber-physical production system, and the validation and proof-of-concept of the proposed method was conducted in an Industry 4.0 pilot line of an assembly process.…”

Along with the development of new-generation information technology, digital twins (DTs) have become the most promising enabling technology for smart manufacturing. This article presents a statistical analysis of the literature related to the applications of DTs for discrete manufacturing lines, researches their development status in the areas of the design and improvement of manufacturing lines, the scheduling and control of manufacturing line, and predicting faults in critical equipment. The deployment frameworks of DTs in different applications are summarized. In addition, this article discusses the three key technologies of high-fidelity modeling, real-time information interaction methods, and iterative optimization algorithms. The current issues, such as fine-grained sculpting of twin models, the adaptivity of the models, delay issues, and the development of efficient modeling tools are raised. This study provides a reference for the design, modification, and optimization of discrete manufacturing lines.

Purpose The purpose of this study is to explore a new assembly process planning and execution mode to realize rapid response, reduce the labor intensity of assembly workers and improve the assembly efficiency and quality. Design/methodology/approach Based on the related concepts of digital twin, this paper studies the product assembly planning in digital space, the process execution in physical space and the interaction between digital space and physical space. The assembly process planning is simulated and verified in the digital space to generate three-dimensional visual assembly process specification documents, the implementation of the assembly process specification documents in the physical space is monitored and feed back to revise the assembly process and improve the assembly quality. Findings Digital twin technology enhances the quality and efficiency of assembly process planning and execution system. Originality/value It provides a new perspective for assembly process planning and execution, the architecture, connections and data acquisition approaches of the digital twin-driven framework are proposed in this paper, which is of important theoretical values. What is more, a smart assembly workbench is developed, the specific image classification algorithms are presented in detail too, which is of some industrial application values.
