As offsite prefabrication and modular construction continue to gain momentum into the future, material supply chain becomes increasingly complex for modern construction projects. Pre-engineered material supply presents itself as a driver for planning crew installation operations on site that involve skilled labor and heavy equipment. This paper proposes a framework for implementing the material-supply-driven project planning and control optimization approach to deal with material delays that take place at the piping spool fabrication shop. Design drawings, contract deadlines, resources availability and material supply patterns are extracted from a real oil and gas expansion project to validate the proposed implementation methodology. An interactive Gantt chart with information on activity start time, duration, and allocated resources is generated to visualize the optimization outcome. In connection with the resource-constrained schedule, material supply-demand patterns over project duration are also visualized. These two forms of visualizations provide insightful decision-making support in coping with material delay while fulfilling project objectives. Ultimately, material-supply driven crew job schedules in correspondence with particular objectives and implementation strategies can be generated, ready to guide project execution.

资源丰富的管道线轴制造调度：材料供应驱动的优化

随着异地预制和模块化建筑在未来的发展势头不断增强，现代建筑项目的材料供应链变得越来越复杂。预先设计的材料供应本身可以作为计划现场安装人员的驱动程序，其中涉及熟练的劳动力和重型设备。本文提出了一个框架，用于实施由材料供应驱动的项目计划和控制优化方法，以应对在管道线轴制造车间发生的材料延迟。设计图纸，合同期限，资源可用性和材料供应模式是从一​​个实际的油气扩展项目中提取的，以验证所提出的实施方法。交互式甘特图，其中包含有关活动开始时间，持续时间，并生成分配的资源以可视化优化结果。与资源受限的进度表相关，还可以看到项目持续时间内的材料供需模式。两种形式的可视化提供了有见地的决策支持，可以在满足项目目标的同时应对重大的延迟。最终，可以生成与特定目标和实施策略相对应的由物料供应驱动的机组工作时间表，以指导项目执行。
