A large-scale bakery is laying out a new production process for its packaged bread, which it sells to several grocery chains. It takes 12 minutes to bake the bread. How large of an oven is required so that the company is able to produce 4200 units of bread per hour (measured in the number of units that can be baked simultaneously)

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.
