 Equipment classes analyzed

• DOE selected two equipment classes for its analyses:

– Class A (fully-cooled machines)– Class B (any machine not considered to be Class A)

• DOE analyzed three different size beverage vending 

machines for each equipment class:

– Small– Medium– Large

 Design-option approach

• DOE analytically derived cost-efficiency curves• Used to supplement and validate the industry data
