Shelf unit parameter

is a parameter for the design of (high-bay) warehouses. R. is equal to the quotient of the height and length of the aisle under consideration multiplied by the quotient of the travel and lifting speed of the storage and retrieval machine. For w=1, the dimensions of the storage rack are optimally adapted to the speeds of the storage and retrieval machine (min. average cycle time (storage clearance)).
