In a linear sequence of operations A$,$ B$,$ C$,$ D$,$ and E$,$ each operation receives one unit from raw materials or the prior operation and outputs one unit. Operation A produces $11$ units a day, operation B produces $6$ units a day, operation C produces $10$ units per day, operation D produces $9$ units a day and operation E$,$ final assembly, produces $8$ units a day.

Operation E receives inputs from other parts of the process that do not pass through the constraint and it sends its output to shipping.

Demand is for $8$ units a day.

Where else might inventory $($buffer$)$ be stored in this production system?
