Multiple factory areas and scattered warehouses pose many challenges to warehouse management. At the same time, it is common to encounter equipment maintenance in the middle of the night, where parts cannot be received, resulting in maintenance delays. Our intelligent small warehouse can be integrated with the maintenance management system. After the system dispatches maintenance task work orders, it also generates material requisition tasks. After authorized by maintenance personnel, they can self collect maintenance materials from the small warehouse. Greatly improve maintenance efficiency while solving the problem of warehouse duty at midnight.
