Suppose there is a two-machine line, where each machine has a 1 minute operation time. There is also a buffer with 1 Kanban card between the machines.

1. How many parts are produced in the 1st hour? Assume the buffer is empty at time 0.
2. How many parts are produced in the second hour?
3. Suppose now that Machine 1 now fails every hour, 10 minutes into the hour, for 10 minutes. How many parts are produced in the first hour? Assume the buffer is empty.
4. How many parts are produced if we increase the Kanban count from 1 to 10 in the first hour? Assume the buffer is empty.
5. Suppose the second machine fails 40 minutes into the hour, every hour for 10 minutes. Assuming the Kanban size is now 2, and the buffer is empty at time 0. How many parts are produced in the first hour?
6. If we increase the Kanban to 10, how many parts are produced in the second hour?
