Abstract

With the development of Modular Prefabricated Construction (MPC), efficiently synchronizing off-site fit-out operations is increasingly important. However, existing synchronization methods lack the flexibility and adaptability to address the challenges in off-site fit-out. This research introduces the concept of Out-of-Order (OoO) synchronization to improve off-site fit-out operations within prefabrication yards. A Cyber-Physical System (CPS)-enabled smart prefabrication yard is proposed to provide real-time visibility and traceability and support decision-making among various stakeholders. To simplify the synchronization problem, a spatial-temporal model is developed for dynamically locating disturbances and uncertainties. Inspired by OoO execution in computer processors, an OoO synchronization mechanism is introduced to ensure smooth workflows and reduce delays. Numerical analysis validates that the OoO synchronization mechanism significantly enhances resource utilization and operational efficiency. This paper advances smart construction by offering a flexible, data-driven method to manage complex, resource-limited production environments.

智能预制场非现场装配的乱序同步

随着模块化预制结构（MPC）的发展，高效同步的非现场装配操作变得越来越重要。然而，现有的同步方法缺乏灵活性和适应性来解决非现场装配的挑战。本研究引入无序（OoO）同步的概念，以改善预制场的非现场装配作业。提出了一种支持网络物理系统（CPS）的智能预制场，以提供实时可见性和可追溯性，并支持各利益相关者之间的决策。为了简化同步问题，建立了一个动态定位干扰和不确定性的时空模型。受计算机处理器中OoO执行的启发，引入了OoO同步机制，以确保流畅的工作流程并减少延迟。数值分析验证了OoO同步机制显著提高了资源利用率和运行效率。本文通过提供一种灵活的、数据驱动的方法来管理复杂的、资源有限的生产环境，从而推进了智能建设。
