The demand-based storage and the use of the two piles for the broken lots reduced the retrieval time by 30.8%, to 1.73 min/m .There is also significant reduction (33.3% on average) in the travel time to and from the picking points, due to the new storage policies adopted. Despite the significant overall reduction on the OP time, the problem of item retrieval remains unresolved. In effect, the current retrieval time is 60% of the total OP time. Reducing the storage depths is not considered presently, as it requires expansion of the warehousing establishments.
