To further understand Z-score, imagine that no safety stock is carried. In this situation, the Z-score is zero. even so, there will be enough inventory to meet demand in 50 percent of cycles. If Z-score equals 1, the safety stock will protect against one standard deviation; there will be enough inventory 84 percent of the time. In the safety stock calculation we will refer to the multiplier as the service factor and use the demand history to calculate standard deviation. In its simplest form this would yield a safety stock calculation of : safety stock = (standard deviation) * (service factor).
