  • arranging a plurality of different types of storage racks into repetitive sets of racks, each set including at least one high movement rack of a predetermined type at the forward end of the set;

    a plurality of medium movement racks of a predetermined type adjacent said high movement rack and being greater in number than said high movement rack; and

    a plurality of low movement racks of a predetermined type adjacent said medium movement racks at the rear of said set and being greater in number than the number of said medium movement racks;

    defining a picking stop adjacent said at least one high movement rack on each set of racks;

    selectively loading items onto said storage racks depending upon the frequency of movement anticipated; and

    retrieving or picking items from said storage racks to fill an order upon arriving at a said picking stop;

    whereby by selectively grouping storage items into frequency of movement, an order selector can stop at said picking stop and select items to fill an order more efficiently by reducing the walking distance required and according to the tine for filling an order.
