Barbara Flynn is in charge of maintaining hospital supplies at General Hospital. During the past year, the mean lead time demand for bandage BX-5 was 60 (and was normally distributed). Furthermore, the standard deviation for BX-5 was 6. Ms. Flynn would like to maintain a 90% service level. Refer to the standard normal table for z-values. a) What safety stock level do you recommend for BX-5? Safety stock = units (round your response to the nearest whole number). b) What is the appropriate reorder point? Reorder Point = units (round your response to the nearest whole number). z 0.38 0.50 0.67 0.84 1.04 1.28 1.41 1.56 1.65 1.75 2.06 2.33 Pr(z) 65 69 75 80 85 90 92 94 95 96 98 99
