Calculating Individual Storage Space Dimensions

Assume l, b and h are the length, width and height of the unit load. The width (W), length (L), & height (H) of the rack structure of the AS/RS aisle are associated to the unit load dimensions & number of compartments as follows:

  L = n_y (l + x)

   W= u (b + y)

   H = n_z (h + z)

Where n_y & n_z are respectively number of load compartments along with the length & height of the aisle; x, y, and z are allowances designed into every storage compartment to provide clearance for the unit load; u is storage depth in number of unit loads. All of the dimensions of rack structure are in 'mm'.

The overall storage capacity of one storage aisle is expressed as follows:

 Capacity per aisle = 2 × n_y × n_z

Constant '2' is multiplied because loads are contained on both of the sides of the aisle.
