Now that you have seen how variability affects a two$-$workstation line, let$$s see what happens in a more realistic line that has more processing steps. Consider a line that has four workstations with processing times ranging from $0\mathrm{.}5$ to $1\mathrm{.}5$ minutes on a uniform distribution $($thus averaging one minute$).$ Consider how you expect the line output and workstation utilization to differ relative to a two$-$workstation line with these workstations $($the line in Part B$)$ and why. After thinking about these questions, click start to play the video and observe how variability affects the line output and workstations$$ utilization of this four$-$workstation line. $7.$ Compare the results for the two$-$workstation line from Part B to this four$-$workstation line. From the videos, note how they differ in terms of blocking and starving, as well as the resulting line output. Hypothesize how the number of workstations might moderate $($a$)$ the relationship between variability and workstations$$ utilization, and $($b$)$ the relationship between variability and line output.
