1.2 A unit load AS/RS is being designed to store 1,000 pallet loads in a distribution center located next to the factory. Pallet dimensions are: x=1,000mm,y=1,200mm; and the maximum height of a unit load =1,300mm. The following is specified: (1) the AS/RS will consist of two aisles with one S/R machine per aisle, (2) length of the structure should be approximately five times its height, and (3) the rack structure will be built 500mm above floor level. Using the allowances a=150mm,b=200mm, and c=250mm, determine the width, length, and height of the AS/RS rack structure
