Fishbone layout for unit-load warehouses

Most warehouses around the world have the same layout, which is characterized by the arrangement of parallel aisles. In 2009, Gue and Meller introduced a layout for unit-load warehouses with two diagonal cross aisles that is expected to have 20% lower travel times.

Cardona et. al 2015 developed an algorithm to create Fishbone layouts. The algorithm receives the desired storage capacity (number of rack-bays) and cost parameters to generate a Fishbone layout that minimizes the operating cost – leasing plus material handling cost – of the warehouse.

Desired number of rack-bays:
Width of rack-bay (inches)
Depth of rack-bay (inches)
Aisle width (ft) :
Leasing cost ($/sqft/year):
Effective working hours per associate (hours/year):
Associates Salaries + Benefits ($/year) :
Equipment depreciation + maintenance ($/year):
Shipments (pallets/year)
Forklift average linear speed (mph)

Highlights

Maximize space utilization in unit-load warehouse using multiple slot heights .
