Research on Automatic Creation of Railway Engineering Material Requirement Planning Based on Construction Plan and Real Dynamic data

With the continuous expansion of railway engineering projects, the challenges faced by material management are becoming increasingly severe. The traditional method of preparing material demand plans is often inefficient and difficult to cope with complex and dynamic construction environments. This article proposes an automatic material demand generation technology based on construction organization plan and real-time dynamic data to address this issue. This method integrates construction plans from BIM systems with real-time dynamic data feedback from on-site IoT devices and digital twins, and combines optimization algorithms and dynamic adjustment mechanisms to achieve intelligent allocation of material requirements under complex engineering conditions. The research results indicate that this technology can effectively improve the accuracy and efficiency of material management, reduce the risk of material backlog and shortage.
