Answer:
840 breads size oven.
Explanation:
According to Little's law,
Inventory = flow rate × flow time
Inventory (I) is the number of flow units that are currently handled by a business process.
I= unknown
Flow rate (R) is the number of flow units going through the business process per unit time.
R= 4200 breads per hour or 70 breads per minute (4200/60)
Flow time (T) is the amount of time a flow unit spends in a business process from beginning to end.
T= 12 minutes.
Inventory = flow rate × flow time
Inventory = 70 breads per minute × 12 minutes
Inventory = 840 breads size oven
Therefore, for the company to produce 4200 breads per minute, 840 breads size oven is required.
