Answer:
(a) 464 units
(b) 1,064 units
Explanation:
Given that,
Mean, M = 300
Standard deviation, SD = 200
Targeting CSL = 95%
Z-value for the 0.95 = 1.645 (Obtained from the Z-tables)
Lead time, L = 2
Standard deviation during lead time = SD × √L
= 200 × √2
= 200 × 1.41
= 282
Safety stock = z × Standard deviation during lead time
= 1.645 × 282
= 463.89 or 464 units
ROP = (M × L) + Safety stock
= (300 × 2) + 464
= 600 + 464
= 1,064 units
