Part c: How many minimum pallets are required if the line is producing at the rate of 0.4 units per hour (or, 1 unit every 2.5 hours)? Show your work.

Answer:

Question 2(10 points: 3+3+4) : Consider a 4-station production line shown below: Note: When there are multiple machines at a stage, the job has to visit only one of the machines at that stage. For example, a job at Stage 2 will visit one of two machines and will take 5hrs. A job at Stage 3 will visit one of 6 machines and will take 10 hours. Each Job is loaded on to a pallet (or a tray) before entering the production process. A job stays on the same pallet through all four steps in the process. Once a job comes out from the last station, the pallet can be cycled back to the first station; this step requires 2.5 hours
