where is the time of pallet turnover, hours (assign it with value of 2 days),

is the ratio that accounts for the time when the pallet is under repair, is assigned for reserve, etc. (has the fixed value of 1,15),

refers to the load capacity of the pallet.

Unit load at warehouses

The further assignment is to design a warehouse that could store the unit load according to the sub-variant and previous estimations. Afterwards, present a final drawing of the unit load warehouse with calculated dimensions shown. Hangar-type warehouses are constructed from concrete or brick according to a typical project topped with no walls but a roof that is supported with several pillars. The width of these warehouses is 12, 18 and 24 meters. The ramps should be at least 3 meters wide on the side of the railway and at least 1,5 meters wide on the side of road transport approach. The suggested length of the warehouse is assigned with value - 20 meters. The height should be 5 meters.

The area of unit load warehouses is calculated on the basis of possible loading capacity , and with the account of time for storage on arrival and departure.
