Abstract

A carousel is an automated ring-shaped warehousing system that rotates either direction bringing items to a picker. We obtain the limiting behavior of the shortest rotation time and the number of steps before a turn, as well as approximate mean rotation time, for one large order with non-uniform items locations.
