2–8°C Constant Temperature API Storage & Sorting
GMP-Compliant Integrated Warehousing Project
Key Results
Regulatory Compliance: Passed Official GMP Audit on the First Attempt
Space Utilization Breakthrough: Storage Density Reached 662 Items/㎡
Labor Optimization: Manual Ledger Workload Reduced by 90%
Project Pain Points
The project involves a 1,200㎡ constant-temperature warehouse area, housing over 800 SKUs of Active Pharmaceutical Ingredients (APIs). These sensitive pharmaceutical raw materials strictly demand a consistent environment maintained at 2–8°C, alongside full-process data traceability dictated by rigorous GMP regulations. Materials undergo full-pallet inbound but split-case/piece-picking outbound fulfillment. The legacy piece-picking workflow relied entirely on manual paper ledgers—a tedious, error-prone protocol that posed severe regulatory compliance and audit risks.
Core Solutions
■Cold-Chain Automated Storage: Deployed a specialized low-temperature tote-level storage and sorting system, driven by cold-tolerant stacker cranes.
■Environmental Software Sync: Established real-time interconnection between the entire warehouse's HVAC/temperature control systems and the central WMS.
■Automated Regulatory Tracking: Configured the system to automatically generate medical-compliance ledgers, eliminating manual logs while maintaining an indelible digital audit trail for all operations.
■Precision Put-to-Light Sorting: Implemented a put-to-light sorting architecture for split-case picking, maximizing picking speed while keeping the entire workflow digitally recorded.
Business Value Delivered
■100% Audit Success: The automated storage architecture seamlessly passed the official GMP regulatory audit on its first run. With end-to-end data traceability secured, all regulatory vulnerability and compliance gaps were thoroughly closed.
■Industry-Leading Space Efficiency: Achieved a high-density warehouse footprint efficiency of 662 items/㎡, maximizing the usage of the expensive constant-temperature volume to fully adapt to large-scale API storage needs.
■Drastic Manual Overhead Relief: Noticeably boosted piece-picking efficiency and slashed manual ledger workloads by 90%, effectively lowering operational overhead while minimizing human error risks.
