$2.$ Keep the buffer at one $\backslash (($b$=3)\backslash ),$ make the process times for both stations equal to $20$ minutes, but set the process CVs to $\backslash (0\mathrm{.}25(\backslash$mathrm$\{$SCV$\}=0\mathrm{.}0625)\backslash ).$

$1.$ What is the throughput?

$2.$ Compute an upper bound on the WIP in the system.

$3.$ Compute an $($approximate$)$ upper bound on the total cycle time. Is this upper bound an acceptable cycle time?

$4.$ What is the utilization of the line?

$5.$ Comment on reducing variability as a strategy.
