Automated Storage and Retrieval Systems (ASRS) consist of computer-controlled systems that automatically place and retrieve loads from defined storage locations. ASRS are chosen to address issues like orders taking too long in factories, wasted time searching for items, lost/damaged products, inaccurate records, and safety hazards. The basic structure of an ASRS includes a storage structure, storage/retrieval machine, storage modules, pickup/deposit stations, and an external handling system. SSI Schafer is a leading provider of ASRS and other logistics systems, having been founded in 1937 and now operating globally with over 50 subsidiaries.

2. Automated Storage and Retrieval
System(ASRS)
It consists of a variety of
computer-controlled
systems for automatically
placing and retrieving
loads from defined storage
locations

3. Why we choose ASRS ???
• Orders spending too much time in the factory, causing
customer deliveries to the late
• Much time spend for searching
• Lost or damaged products and inaccurate records
• Waste much space
• Workers are exposed to dangers
 If the answer to all of these questions is “YES” for a given
material handling system, then the system can be

4. Basic structure of AS/RS
1)Storage structure
2)S/R machine (Storage /
Retrieval)
3)Storage modules (e.g.,
pallets for unit loads)
4)one or more pickup-and-
deposit stations
5)External handling system

5. Basic structure of AS/RS
1. Storage structure
Fabricated steel
Rack frame work
Supports the load contained in the
AS/RS
To store Inventory items
2. Storage/Retrieval Machine
It is capable of both horizontal and
vertical movement
Used to move items in and out of the
inventory

6. Basic structure of AS/RS
3. Storage Modules
Unit load containers is used to hold an
inventory items such as pallets, steel wire baskets,
containers etc
The modules are generally made to a
standard base size capable of being stored in the
structure and moved by S/R Machines
4. Pickup and Deposit (P/D) Stations
loads transferred to in and out of the AS/RS
stations
located at the end of aisles
Number of P/D Stations depends upon the
orgin point from incoming and outgoing loads

7. Basic structure of AS/RS
5. External handling system
bring load to AS/RS and takes load
away
Eg- Pallet truck etc

16. Applications
•Unit load storage and handling system –
Warehousing for finished goods/Products
•Order Picking – Used to store and retrieve
materials in less than full unit load quantities such
as man-on-board or mini-load applications
•Work-in-process – Support just-in-time production
activities, buffer storage, and as integral part of
assembly systems

17. Conclusion
AS/RS is a great system which was developed to improve the
storage systems used in industries to handle, store and retrieve
materials with precisions, accuracy and speed under defined degree of
automation.
