This study evaluates current and alternative physical inventory methodologies for the Wright-Patterson Medical Center Supply Activity. Four potential physical inventory alternatives were examined 1 100 percent annual physical inventory 2 statistical sampling, 3 continuous cyclic and 4 stratified cyclic. For each alternative the researchers used historical data and a site survey to estimate the effect on physical inventory costs and impact on customer service. The researchers found that statistical sampling was the most economically feasible alternative for the Wright-Patterson Medical Center. However, the method of stratified cyclic produced less extreme scores in both physical inventory cost and customer service parameters than did statistical sampling. The researchers found that further research is needed in the recommended methodologies of statistical sampling and stratified cyclic.
