$2\mathrm{.}6.$ For the factory and initial conditions of Problem $2\mathrm{.}4,$ compute the long$-$run

average factory throughput, cycle time and $x-$factors for various constant work$-$in$-$

process levels of $1$ through $5.$

$2\mathrm{.}7.$ Compute the long$-$term average throughput, cycle time and $x-$factors for this

factory for fixed work$-$in$-$process levels of $5$ and $10$ for the four machine serial

flow factory model below where the constant processing times are listed on the

machines. Argue that the results of the WIP level of $10$ are the measures reported

for the example factory with the new Machine $2$ with a processing time of $1\mathrm{.}5$ hours.
