CPIM Practice Exam

What is the order quantity when there are 210 units on hand, a demand of 50 units per day, and a review period of 20 days plus a lead time of 3 days?

1. 1,040 units

2. 1,090 units

3. 1,250 units

4. 1,300 units

The correct answer is: 1,040 units

To determine the order quantity, it’s essential to calculate the total demand during the review period and the lead time, then assess the current inventory to find out how much more is needed. First, we need to calculate the total demand. The review period is 20 days, and the lead time is an additional 3 days, making the total period for which we need to plan 23 days. Given the demand of 50 units per day, the total anticipated demand is calculated as follows: Total Demand = (Daily Demand) x (Total Period) Total Demand = 50 units/day x 23 days = 1,150 units Next, we compare this demand with the current inventory on hand. With 210 units currently available, we subtract this from the total demand: Required Order Quantity = Total Demand - Current Inventory Required Order Quantity = 1,150 units - 210 units = 940 units However, it seems there might be a misunderstanding here regarding the interpretation of what constitutes an order quantity. The calculation should include safety stock or adjustments depending on the organizational policies and practices, which can vary. It’s also important to discuss that the calculation here led to determining a base order quantity of 940 units, which
