Analyzing the movement of goods on warehouse shelves involves quantifying the frequency and distance of goods movement during storage, which is a key method for optimizing shelf layout, inventory management, and operational efficiency.
Below are its core content and applications:
Definition and Calculation of Goods Movement
- Definition: Goods movement (P) comprehensively reflects the activity level of goods during storage and handling. The calculation formula is:
P = F × D
- F: The frequency of goods movement within a certain period (e.g., the number of times goods enter and leave the warehouse);
- D: The average distance of each movement.
- Significance: Goods movement can identify high-flow, medium-flow, and low-flow goods, providing a basis for shelf zoning and management strategies.
Goods Movement Classification and Management Strategies
- Classification Standards:
- High goods movement (Class A): High-frequency movement, high-value, or high-demand goods (such as best-selling products). These should be placed near entrances or operating areas, using flow-through shelves, automated warehouses, and other quick access equipment.
- Medium goods movement (Class B): Moderately flowing goods, which can be placed in conventional shelf areas to balance retrieval efficiency and storage space.
- Low goods movement (Class C): Low-frequency movement, low-value goods (such as spare parts), suitable for multi-layer stacking or mezzanine shelves to reduce space occupancy.
- Management Strategies:
- Differentiated inventory control: Maintain high inventory levels for Class A goods, and use on-demand replenishment or JIT for Class C goods;
- Dynamic adjustment: Monitor changes in goods movement using WMS or RFID technology, and adjust shelf locations or classifications in a timely manner.
Data Collection and Analysis Methods
- Data sources: Warehouse Management System (WMS), RFID, sales records, inventory accounts, etc. Ensure data is real-time and accurate.
- Analysis tools:
- ABC classification method: Based on goods movement, sales, etc., goods are classified into A/B/C categories, concentrating resources to optimize the management of Class A goods;
- Pareto principle: Focus on the 20% of goods that account for 80% of the flow, prioritizing the optimization of their storage layout.
Impact on Shelf Layout
- Core principles:
- High goods movement near aisles: Shorten handling distances and improve efficiency (e.g., Class A goods near the main aisle);
- Low goods movement on upper levels or edges: Utilize high-bay shelves or remote areas for storage to reduce space costs;
- Compatibility with operating modes: E-commerce warehouses need to adapt to automated sorting, while manufacturing warehouses need to meet the high-frequency retrieval needs of production lines.
Technology and Trends
- Intelligent upgrades: Combining the Internet of Things, big data, and AI technology to monitor goods movement in real-time and dynamically adjust shelf layouts (such as intelligent robot picking systems);
- Green energy saving: Using lightweight materials and modular design to reduce energy consumption and carbon emissions;
- Customized services: Designing special shelves according to industry characteristics (such as food, electronics, cold chain) to balance functionality and compliance.
Summary
Goods movement analysis quantifies the characteristics of goods flow, driving the scientific layout and efficient management of warehouse shelves.
Companies need to combine ABC classification, data monitoring, and technological tools to dynamically optimize storage strategies to reduce costs, improve response speed, and adapt to market changes.
In the future, intelligence and greening will become the core direction of warehouse shelf goods movement management.
