Modern airports handle thousands of items daily — from luggage and cargo to operational materials and equipment. To manage such high volumes efficiently, automation plays a key role. One of the most advanced technologies used at Dhaka Airport is the Automated Storage and Retrieval System (ASRS).
What Is an ASRS System?
An ASRS (Automated Storage and Retrieval System) is a computer-controlled system that automatically places and retrieves items from storage locations with high accuracy and efficiency. It reduces manual handling, saves time, and optimizes storage space by using automated machines and conveyor systems.
The ASRS Area at Dhaka Airport
The ASRS area at Dhaka Airport is a well-organized zone equipped with:
-
Conveyor systems
-
In and Out Stations
-
Storage bins / empty bin plates
-
Stacker cranes
-
WCS (Warehouse Control System) and TCS (Terminal Control System) interfaces
Let’s understand how the entire process works step by step.
Step 1: Placing the Storage Bin
In the ASRS area, storage bins or empty bin plates are first placed at the In Station. This is the starting point for every item entering the system.
Step 2: Scanning with HHT
Each bin is scanned using an HHT (Handheld Terminal) device. This scan captures all necessary data about the bin — such as its ID and status — and sends the information to the WCS system for further processing.
Step 3: Sending Data to WCS
Once scanned, the data is transmitted to the Warehouse Control System (WCS). The WCS acts as the brain of the ASRS, deciding where each bin should be stored within the system.
Step 4: Movement via Conveyor
After the command is issued, the conveyor system carries the bin from the In Station to the stacker crane’s In Station. The conveyor ensures smooth and precise transportation without any manual intervention.
Step 5: Storage by the Stacker Crane
At the In Station of the stacker crane, the WCS sends a command to place the bin in a specific location on the ASRS rack. The stacker crane then automatically stores the bin in the designated rack position.
Step 6: Monitoring via WCS and TCS Interface
Both the WCS and TCS interfaces display real-time data, showing exactly which rack location holds the newly scanned bin or empty bin plate. This digital visibility ensures efficient tracking and retrieval when needed.
Why the ASRS System Matters
The ASRS system at Dhaka Airport brings several key advantages:
-
Automation and accuracy – Reduces human error and improves operational precision.
-
Space optimization – Maximizes use of vertical and horizontal storage areas.
-
Faster operations – Speeds up both storage and retrieval processes.
-
Real-time tracking – Enables instant visibility of all stored items.
-
Enhanced safety – Minimizes manual handling and workplace risks.
Conclusion
The ASRS system at Dhaka Airport represents a major step toward smart automation in airport logistics. By combining conveyor technology, stacker cranes, and intelligent control systems like WCS and TCS, it ensures seamless handling of storage bins — from entry to storage and retrieval.
This modern system not only enhances efficiency but also sets a new standard for operational excellence in airport infrastructure.
