Given the information in Question$-2($Ik and Ok$)$ and the information in the table below, how

many machines are needed to perform each operation $($round up to the nearest integer$)?$

Assume operations $1,2,$ and $3$ run for $16$ hours per day, five days per week. Operation $4$ is

available for eight hours per day, five days per week.

$-$ Assuming that operations $13$ are part of a dedicated manufacturing cell, that operation $4$ is

performed by a general$-$purpose machine that is used specifically for rework, and that

machines needed for operation $4$ are located somewhere else in the facility. Recommend an

alternative strategy for performing operation $4($rework$),$ discussing specifically the issues

related to your strategy $($use numerical results if applicable$)$
