Powered Mobile racking
Powered mobile racking is
effectively single deep APR, with the racking except the end or outer rows
mounted on electrically powered base frames. Operationally it has similar
characteristics to APR but it is slower in use and the pallet position
utilization is likely to be similar to APR at 95%. This type of storage is
expensive in equipment and floor costs and it tends to be slow in operation.
However it gives very dense storage and is suitable for the typically large
number of product lines have low stock and now throughput. It also finds use in
cold- storage applications where space costs are especially high and however
temperature variations are reduced by cutting the air space in the storage
area.
Pallet live storage
Live storage system are made up
made up of inclined gravity roll conveyors laid out side by side and at a
number of vertical levels. Pallets are fed in at the higher end and removed as
required at the lower. Such a system imposes FIFO. The only accessible pallets are
at the out feed end so any one lane should only hold pallets of the same
product line.
Pallet live storage systems are
suitable for very fast – moving product lines. They can provide effective order
picking regimes which automatically refill empty locations, and also provide
physical separation between picking and replenishment operations.
Small item storage systems
As with palatalized storage system
there is a range of different types system for holding small items. With small
item storage it often happens that different system are incorporated into one
installation. Consequently the concept of standard equipment sizes and molecularity is important for small item storage systems.
The following lists are some of
the storage systems used for small items:
·
Shelving
·
Tote bins
·
Drawer units
·
Dynamic
systems- mobile and live storage
·
Mechanized
systems- carousels and mini loads
Summary
Warehouses may be distributed in
the field in order to shorten to shorten transportation distances to permit
rapid response to customer demand. This study material shows us the process of
decision making in the selection of type of warehouse between private and
public warehouse and its location preferences in the whole supply chain
network.
It gives various functions
involved in warehouse operations. It also gives the selection of storage system
required to suit various types of goods in order to increase the efficiency of
warehouse operations.
