A company is studying the inventory stocking policy for a product (#A123). The company uses a fixed-order quantity system to manage inventory. Demand per day is normally distributed with a demand per day of 210 and a standard deviation of 5 per day. Based on historical lead time of 4 days the current reorder point is set at 860 units.

The company has some new information about the supplier. Because of a natural disaster in the supplying country, the lead time has increased to 9 days.

A company is selling coffee mugs. Weekly demand for the mug is normally distributed with a mean of 5000 and a standard deviation of 1000. The replenishment lead time is 16 weeks.
