said replenishing and picking racks being substantially identical, corresponding to each other, and arranged so as to oppose the outlet opening side of the first shelves with the inlet opening side of the second shelves, leaving a corridor therebetween;
a shifting mechanism which can access substantially all of the opposed shelf openings, said shifting mechanism being disposed within said corridor for shifting the stocking articles from the replenishing rack onto the picking rack when a number of stocking articles within the picking rack is reduced below a predetermined number;
a replenishing mechanism for replenishing the shelves to be replenished in the replenishing rack;
a picking mechanism for picking the stocking articles in the picking rack;
first transfer means for transferring the stocking articles from a warehousing berth having a stage for receiving stocking articles to be stored to the replenishing mechanism, said first transfer means having first conveying means for conveying received stocking articles; and
second transfer means for transferring the stocking articles from the picking mechanism to a delivery berth having a stage for delivering stocking articles to be shipped, said second transfer means having second conveying means for conveying the stocking articles to be shipped;
whereby replenishment and delivery of the stocking articles can occur substantially at the same time.
