There are two main types of storage systems: conventional and automated. Conventional systems include bulk storage, rack systems using cantilever, portable, drive-through, or flow-through racks, shelving and bins, and drawer storage. Automated storage systems include ASRS and carousel systems, which use computer control to automatically place and retrieve loads and provide benefits like reduced costs, workforce needs, and increased safety and accuracy.

1. Storage system
• It is of two types
– Conventional storage method
• Bulk storage
• Rack system
• Shelving and bins
• Drawer storage
– Automated storage system
• ASRS
• Carousel system

2. Conventional storage methods : bulk storage
• Storage of stock in an open floor
• Stock in unit loads on pallets
• Highest density is achieved
• Flexibility is increased by arranging in rows

3. Conventional storage methods : Rack system
• It provide a method of stacking unit load
vertically
• No need to provide support
– Its type
• Cantilever racks: supporting horizontal block
• Portable racks: portable box frames and can be stacked
on top of each other
• Drive through racks :consist of aisels (a space for
walking), open at each end
• Flow through racks

4. Conventional storage methods : Rack system
Cantilever racks Portable racks

5. Conventional storage methods : Rack system
Drive through racks flow through racks

6. Conventional storage methods : shelving and bins
• Shelf is horizontal platform, supported by a wall
• Bins are container and boxes

7. Conventional storage methods : Drawer storage
• Finding items is difficult in shelves if the shelf is far
above or far below eye level.

8. Automated storage and retrieval system (ASRS or AS/RS)
• An automated storage and retrieval system (ASRS or AS/RS) consists of a
variety of computer-controlled systems for automatically placing and
retrieving loads from defined storage location
• Application
– There is a very high volume of loads being moved into and out of
storage
– Storage density is important because of space constraints
– No value is added in this process (no processing, only storage and
transport)
– Accuracy is critical because of potential expensive damages to the load

9. Automated storage and retrieval system (ASRS or AS/RS)
• benefits for supply chain management
• cut expenses by minimizing the amount of unnecessary parts
• lowering workforce requirements and increasing safety
• Modeling and managing the logical representation of the physical storage
facilities
• Enabling a seamless link to order processing and logistics management in
order to pick, pack, and ship product out of the facility
• Tracking where products are stocked
