Scenario C: Suppose you have a three-task sequence. All customers go to Task A. After task A, 20% of customers go to Task B; the other 80% go to task C. After task B or C, all customers then go to Task D before leaving. There is an inventory buffer in between each station. Each buffer is empty at the start of each day.

Suppose throughput capacities are as follows. Task A: 30 customers/hour; task B: 10 customers/hour; task C: 20 customers/hour; task D, 32 customers/hour.
