Consider a 40-foot conveyor-paced assembly line with ten workers placed along it. At any time, the line has 10 units of product on it, spaced evenly so that each of the ten workers can be working on one of the items.
Theses wotkers are paid $9/hr for the normal 7.5 hour-shift that they work on the line each day, with 50% premium for any overtime work. The daily demand for the product is 300 units. Demand is stable.
To run the line for single shift with no overtime, what should be the speed of the conveyor to satisfy demand?
