Answer: The component with the highest annual usage value is A01 with 62,500. Therefore, I suggest that the company keeps the tightest control over component A01 to ensure that it is always in stock and available to meet customer demand.
Explanation: To determine which product to keep the tightest control over, we need to calculate the annual usage value for each component, which is the product of annual demand and unit cost.
The annual usage value for each component is:
A01: 250 x 250 = 62,500
B02: 75 x 90 = 6,750
C03: 20 x 60 = 1,200
D04: 150 x 150 = 22,500
E05: 100 x 75 = 7,500
Based on these calculations, the component with the highest annual usage value is A01 with 62,500. Therefore, I suggest that the company keeps the tightest control over component A01 to ensure that it is always in stock and available to meet customer demand.
