The geographic size and overall complexity of the U.S. Army supply chain leads to frequent problems that disrupt the flow of goods to essential operations. This study investigates inventory stock outs which can ripple through the chain and affect military readiness. This study focuses on two aspects of stock outsï¼› first, I statistically investigate the primary causes of stock outs, and second, I develop a technique to predict their occurrence. The ability to predict stock outs allows the Army to develop a preventative measure which may ultimately reduce the Army’s cost of supplying its troops.
