Hospital Laundry

The laundry department of a large hospital contains energy efficient industrial washing machines for laundering sheets and towels. High energy $($HE$)$ laundry detergent is automatically dispensed at the start of each load. If an insufficient amount of detergent is dispensed, the laundry will not be completely cleaned, while too much is unnecessarily costly and can damage the machine$$s bearings.

Tire Pressure

One of the tasks on the turnaround list for a rental car agency is to check and adjust tire pressure. When a tire is over$-$inflated, it can cause a bouncy ride and poor handling. If it is under$-$inflated, it can cause premature wear due to increased friction.

Filled Donuts

Bob$$s Bakery carries a wide variety of pastries, including his famous filled donuts. Each donut is injected with a flavored jelly or cream. The customers complain if they feel that there isn$$t a sufficient amount of filling in their donuts. Overfilled donuts are messy and waste costly filling.
