The retrieval throughput, also known as the retrieval rate, is an important performance indicator in warehouse logistics that measures the efficiency and productivity of retrieval processes. It results from the ratio of the transport units to be retrieved per time unit at the reference locations to the total time of a complete work cycle with retrieval operations, as defined in VDI 4480.

The retrieval throughput is calculated by dividing the number of transport units to be retrieved per time unit by the total time of a complete work cycle with retrieval operations, and is usually expressed in units such as transport units per hour.

A high retrieval throughput indicates efficient execution of retrieval processes, while a low retrieval throughput may indicate possible bottlenecks or inefficient workflows. Warehouse operations therefore usually strive for continuous improvement of retrieval throughput in order to increase productivity and customer satisfaction.

A variety of factors can influence retrieval throughput, including warehouse layout design, the efficiency of picking processes, the availability of warehouse resources and the use of technologies such as automated storage solutions or conveyor systems.

By analyzing retrieval throughput, warehouse operations can identify bottlenecks, optimize inefficient processes and maximize resource utilization to improve warehouse performance. An efficient retrieval throughput thus contributes significantly to the competitiveness and profitability of warehouse operations.
