Material Management System

Leveraging the powerful capabilities of the Internet of Things (IoT), this system enables comprehensive big data management for urban rail transit material assets, including: material warehousing and production process management; warehouse inbound/outbound alert management for work teams; production material quota-based inventory safety alert management; statistical data management for material consumption quotas; and a complete end-to-end workflow—from material asset planning, procurement, acceptance, storage, and distribution, to work-team material requisition, storage, and withdrawal—along with information entry, query, and statistical analysis. The system also supports the configuration of warehouse inbound/outbound alerts, material quota safety alerts, and statistical analysis of material consumption quotas, thereby establishing a unified big data-driven warehousing and operational platform for material management. All operational workflows incorporate an electronic signature mechanism, and the platform supports file scanning and upload, image capture and upload, as well as automatic linkage to corresponding reports, achieving paperless material management operations.
