Large-scale personalization is becoming a reality. To ensure market competitiveness and economic benefits, enterprises require rapid response capability and flexible manufacturing operations. However, variant design and production line reconfiguration are complicated because it involves the commissioning, replacement, and adaptive integration of equipment and remodification of control systems. Herein, a digital twin-driven production line variant design is presented. As a new technology, the digital twin can realize the parallel control from the physical world to the digital world and accelerate the design process of the production line through a virtual-real linkage. Simultaneously, the actual production line can be simulated to verify the rationality of the design scheme and avoid cost wastage. Four key technologies are described in detail, and a production line variant design platform based on digital twin is built to support rapid production line variant design. Finally, experiments using a smartphone assembly line as an example are performed; the results demonstrate that the proposed method can realize production line variant design and increase production efficiency.
大规模定制化正成为现实。为了确保市场竞争力和经济效益，企业需要具备快速响应能力和灵活的制造运营。然而，由于涉及设备的调试、更换和自适应集成以及控制系统的改造，变体设计和生产线重构较为复杂。为此，提出了一种数字孪生驱动的生产线变体设计。作为一种新技术，数字孪生可以实现从物理世界到数字世界的并行控制，通过虚实联动加速生产线的设计过程。同时，可以模拟实际生产线来验证设计方案的合理性，避免成本浪费。详细描述了四项关键技术，并构建了基于数字孪生的生产线变体设计平台，以支持快速的生产线变体设计。最后，通过智能手机装配线的实例实验进行了验证；结果表明，该方法可以实现生产线变体设计，提高生产效率。
