Comparison

Task Interface

• Easier to implement, with simple interface (picking list model).
• Covers most standard requirements.
• Some advanced/specific requirements can be difficult to implement efficiently.
• AutoStore decides the picking sequence.

The Task Interface covers the most usual requirements. Many warehouse processes follow the picking list model, and the properties of the task groups support many common requirements. However, there are scenarios that do not fit the model supported by the Task Interface. Some examples can be production processes or batch picking processes where the Ports combine multiple picking lists.

Bin Interface

• The WMS has full control of the Bin sequence.
• Possible to implement advanced requirements/scenarios that are difficult to express with the Task Interface.
• More complex to implement.
• Requires good understanding of AutoStore behavior, such as preparation/digging/transportation costs.
• WMS must plan Bin preparations and Port queues.
• More responsibility for the WMS as implementation and strategies will have big impact on performance/throughput.

The Bin Interface is more flexible and gives the WMS full control of the Bin sequence.

📘

Batch picking processes may still use the Task Interface when the picking lists can be combined into task groups in advance. However, the Bin Interface allows a more dynamic approach since the grouping can be decided later.
