30. Storage

[MUSIC] Welcome back to our lesson on storage. Upon completion of this lesson, learners should be able to describe the fixed and random storage location systems and their differences, describe factors that favor fixed location systems and random location systems,
describe an Automated Storage and Retrieval System, and, identify key metrics used to measure storing and restocking performance.
Goods are moved from receiving to their assigned storage location, and moved from their storage locations as needed using one of the following types of handling equipment. Operator-controlled, manual hand trucks and carts, operator-controlled power-assisted devices such as forklifts, platform trucks, and cranes, or automatic handling systems such as conveyors and AGVs, automatic guided vehicles.
There are two categories of storage locations systems, fixed location systems, where specific slots or lanes are allocated and dedicated to specific items, and random location systems, where storage locations are assigned on a random basis and stock is placed wherever a space is available.
Fixed storage location warehouses may not make the best use of available space, because specific slots and lanes must be dedicated to items that may fluctuate substantially in volume.
A random location system uses space in an optimal fashion. However, it is dependent on a computer system that allows for the automatic and accurate identification of alternative picking and placements slots for the items as they move around the warehouse from day to day.
Automated Storage and Retrieval Systems include carousels and manned ride machines. ASRSs combine storage equipment with automated handling technology and interfaces with manual automated handling systems, such as forklifts and conveyors. Goods are delivered to a staging area, the ASRS removes the goods from the staging area to place them in a storage location within the ASRS.
The three ASRS types which are commonly found are differentiated by the size of the items handled, and they include unit load, miniload, and microload.
Unit load ASRS handle large palletized or unitized loads. Microload and miniload ASRS handle smaller packages and individual items that can be placed into containers.
Key performance indicators include, at the cost level, cost per stock line, productivity level, maybe stocks per labor hour, utilization, includes utilization percentage of labor and equipment, quality, includes perfect stocking percentage, and cycle time, the time taken for each item to be stocked.
Key performance indicators in storage include storage cost per item, average warehouse capacity used, peak warehouse capacity used, or the percentage of the peak warehouse that is being used, dock-to-stock cycle time in hours, lines received and restocked per labor hour, and the number of units filled as a percentage of the total ordered. This is a fill rate measure.
For this lesson, in addition to watching the lecture, you will want to watch the following YouTube video, 6 Types of Warehouse Storage. The link to these videos can be found at the lower right side of this lesson shown as links. In this lesson, we described the fixed and random storage location systems and differences, described factors that favor fixed location systems and random location systems, described an Automated Storage and Retrieval System and identified key metrics used to measure storing, storage, and restocking performance. Thank you for watching and we’ll see you on the next lesson. [MUSIC]
