Automated Storage and Retrieval Systems (AS/RS) are typically used in applications where there is a very high volume of loads being moved into and out of storage where storage density is important because of space constraints, and where no value adding content is present in this process. They are used widely in both Manufacturing and Distribution operations to hold and buffer the flow of material moving through the process to the ultimate end user. Most systems operate in a fully automated mode with little or now human involvement in the handling of material except at the controlled input and output stations to the system. This results in extremely high inventory accuracy.

AS/RS benefits include:

• Bringing material to the operator cutting cycle time by eliminating wait, walk, and search time.
• Reduces work-in-progress inventory. Better inventory accuracy and better responsiveness to need result in reduction or elimination of "safety stock" in the overall inventory model. This has the net effect of inventory reduction.
• Dramatically increases operator productivity. The "Part to Picker" model of order fulfillment is 3 to 5 times more productive that having the picker travel to the part to complete the fulfillment .
• Provides real-time inventory control with instant reports. With near 100% accuracy and real time information about the inventory on hand, achievable commitments can be made to your customer – as opposed to "best efforts promises".
• Improves product quality and productivity. Real time information, faster response to a need, physical protection, and traceability of material access all contribute to a better process where time can be spent on improving the quality of the process instead of on expediting material to a point of use.
