Analysis of Shelf Space Allocation at the Wright-Patterson Air Force Base Commissary

摘要

The purpose of this research was to analyze shelf space allocation at the Wright-Patterson Air Force Base Commissary. THe commissary had a product in stock goal of 99 percent, which was not being met for all products. The research addressed two different methods of shelf space allocation, within existing constraints of product mix and shelf space available, to limit the out-of-stock situations. The study was accomplished by an experiment that used an initial data collection period to establish a baseline of sales and stockouts for three product groups. Shelf space was then reallocated for 2 product groups by equalizing the individual product turnover ratios for 1 group, and by stocking to meet 99 percent of demand for the other product group. After a posttest data collection period, comparisons were made using paired Tests to compare pre and posttest sales and stockouts for products in all three product groups. A Chi Square test was used to test the relationship between changes in product level stocked, sales and stockouts. The results showed a significant decrease in stockouts, but a cause could not be proved.
