Which warehouse operating principle focuses on height utilization?

Vertical lift modules (VLM) are a highly dense media for warehouse storage.  As a storage method, there a few clear advantages of this handling criteria

Excellent use of vertical height.  Up to 90% space savings over steel shelving.

Modular and can be increased in height over time

For me it should be

Design Criteria - as height utilization will be come in  design criteria.

I fully agree with the answers been added by EXPERTS...............thanks.

Hello Team,

Whether the warehouse is a small manual operation or a large automated facility, the following three principles are relevant: 

·         Design criteria, 

·         Handling technology, and 

·         Storage plan.

Design Criteria

Warehouse design criteria address physical facility characteristics and product movement. Three factors to be considered in the design process are: 

·         the number of stories in the facility: 

·         The ideal warehouse design is limited to a single story so that product does not have to be moved up and down. 

·         The use of elevators to move product from one floor to the next requires time and energy. 

·         The elevator is also often a bottleneck in product flow since many material handlers are usually competing for a limited number of elevators. 

·         While it is not always possible, particularly in central business districts where land is restricted or expensive, warehouses should be limited to a single story.

Handling technology

The second principle focuses on the effectiveness and efficiency of material-handling technology.  The elements of this principle concern, i.e.:

·         Height utilization: 

·         Regardless of facility size, the design should maximize the usage of the available cubic space by allowing for the greatest use of height on each floor. 

·         Most warehouses have 20- to 30-foot ceilings          (1 foot = 12 inch; 1 inch = 2.54 cm), although modern automated and high-rise facilities can effectively use ceiling heights up to 100 feet. 

·         Through the use of racking or other hardware, it should be possible to store products up to the building's ceiling. 

·         Maximum effective warehouse height is limited by the safe lifting capabilities of material-handling equipment, such as forklifts.

·         product flow:

·         Warehouse design should also allow for straight product flow through the facility whether items are stored or not. 

·         In general, this means that product should be received at one end of the building, stored in the middle, and then shipped from the other end. 

·         Straight-line product flow minimizes congestion and confusion.

·         movement continuity: 

·         Movement continuity means that it is better for a material handler or piece of handling equipment to make a longer move than to have a number of handlers make numerous, individual, short segments of the same move. 

·         Exchanging the product between handlers or moving it from one piece of equipment to another wastes time and increases the potential for damage. 

·         Thus, as a general rule, fewer longer movements in the warehouse are preferred.

·         movement scale economies:

·         Movement scale economies imply that all warehouse activities should handle or move the largest quantities possible. 

·         Instead of moving individual cases, warehouse activities should be designed to move groups of cases such as pallets or containers. 

·         This grouping or batching might mean that multiple products or orders must be moved or selected at the same time. 

·         While this might increase the complexity of an individual's activities since multiple products or orders must be considered, the principle reduces the number of activities and the resulting cost.
