Supplier-contractor coordination approach to managing demand fluctuations of ready-mix concrete

Although advancements have been made in the management of projects due to digitalization and automation technologies, efficient use digital data is still lacking for coordination supply chain. This paper presents an approach that allows data-driven schedule-oriented chain face demand fluctuations. The consists two main steps contractors should take: 1) monitor fluctuations based on a 4D model captures as-built status updated look-ahead schedules, 2) make decisions modify original orders accommodate where are determined by heuristic evolutionary algorithm. As proof concept, demonstrated using example project featuring five-day in-situ construction concrete walls. Results from this show improves responsiveness planning ordering. result, leads improved collaboration between suppliers projects.
