Graphical solution:
Answer: 90.32%
Explanation:
Weekly demand (d) = 120
Standard deviation = 10
Lead time (l) = 4
Reorder point = 506
The reorder point is calculated as:
506 = 120 × 4 + Z × 10 × ✓4
Solving for Z will give us 1.3
Then, we check this in the z table which will give us p = 0.9032
Therefore, the service level is 90.32%.
