Logistics interfaces with manufacturing throughout the entire production process need synchronous operations. For achieving integrated organization and operations between manufacturing and logistics, this article introduces the concept of shop-floor logistics and manufacturing synchronization with four principles, including: 1) synchronization-oriented manufacturing system; 2) synchronized information sharing; 3) synchronized decision making; and 4) synchronized operations. The marriage of the principles rendered the development of an overall framework of the Industrial Internet of Things (IIoT) and digital twin-enabled graduation intelligent manufacturing system (GiMS). A mixed-integer programming-based synchronization mechanism is proposed under GiMS. To meet the requirement of fast decision making in real-life shop-floor logistics and manufacturing synchronization problems, an equivalent constraint programming model is developed and tested. The observation and analysis of the case company show the advantage of the proposed concept and approach with the best performance regarding key performance indicators. The concept of synchronization provides an insight for understanding the interaction of logistics and manufacturing at the operational level. This article potentially enables manufacturers to reevaluate and develop their manufacturing planning and control strategies in the IIoT and digital twin-based manufacturing environment.
在整个生产过程中，物流与制造的接口需要同步运作。为了实现制造与物流之间的集成组织和运作，本文介绍了车间物流与制造同步的概念，并提出了四项原则，包括：1）面向同步的制造系统；2）同步信息共享；3）同步决策；4）同步运作。这些原则的结合促成了工业物联网（IIoT）和基于数字孪生的分级智能制造系统（GiMS）总体框架的发展。在GiMS框架下，提出了一种基于混合整数规划的同步机制。为了满足实际车间物流与制造同步问题中的快速决策需求，开发并测试了一个等效约束规划模型。对案例公司的观察和分析表明，所提出的概念和方法在关键绩效指标方面具有最佳性能优势。同步概念为理解物流与制造在运营层面的相互作用提供了一个视角。本文有望使制造商在基于工业物联网和数字孪生的制造环境中重新评估并制定其制造规划和控制策略。
