Warehouse Management System Overview

Warehouse Management System is a critical component of Enterprise Resource Planning (ERP). It encompasses essential business processes such as inventory control, order processing, procurement management, and shipment tracking. This system aims to increase operational efficiency, reduce errors, optimize inventory levels, and ensure a smooth supply chain flow. The key functional modules include:

1. Inventory Management: The system tracks real-time inventory levels, automatically updating stock data to prevent overstocking or stockouts. Through inventory counting, accuracy is maintained, preventing asset loss.

2. Inbound and Outbound Operations: Supports automated workflows for receiving and shipping, including creating receiving orders, inspection, storage, and generating picking lists, packing, and dispatching shipments. Barcode or RFID technology ensures quick and accurate record-keeping.

3. Batch Tracking: For products with batch information, the system traces each batch’s origin, destination, production date, and expiration date, aiding in quality tracking and product recalls.

4. Barcode/RFID Management: Accelerates stock counting and warehousing speed, reduces manual errors, and improves data accuracy with barcode or RFID technology.

5. Alert Mechanism: Triggers alerts when stock levels fall below preset thresholds, notifying the procurement team to prevent stockout risks.

6. Order Management: Integrates with the sales system to handle orders, synchronize inventory, and ensure accurate order fulfillment.

7. Procurement Management: Assists in creating purchase plans, suggesting quantities based on demand forecasts and current inventory, optimizing costs.

8. Reports and Analysis: Provides various reports such as inventory turnover and inactive materials reports to help analyze stock status and make decisions.

9. Interface Integration: Seamlessly integrates with ERP, WMS, TMS, and other systems for collaborative work across the supply chain.

10. Permission Management: Assigns different permissions based on roles to ensure data security and prevent unauthorized operations.

Detailed Design Documentation covers system architecture, database design, module division, interface design, flowcharts, and class diagrams. Typically, a three-tier architecture is used, with key entities like materials, stock, and orders forming the database core. Module segmentation includes inventory, orders, and reports, while interface design addresses system interaction. Implementing this warehouse management system enables enterprises to optimize inventory, enhance operational efficiency, reduce costs, and increase customer satisfaction.
