Consider a four$-$station line in which all stations consist of single machines. Station $2$ has average processing times of $2$ hours per job, while the remaining stations have average processing times of $1$ hour per job. Answer the following, under the assumption that the process times are deterministic $($as in the best case$).(10$ points each$)$What are and for this line? $!"$ How do and change if a second identical machine is added to station $2?$ What $!"$ effects will this have on performance $($i$.$e$.,$ cycle time and throughput$)?$How do and change if the machine at station $2$ is speeded up to have average $!"$ processing times of $1$ hour? What effects will this have on performance?How do and change if a second identical machine is added to Station $1?$ What $!"$ effects will this have on performance?How do and change if the machine at Station $1$ is speeded up to have average $!"$ processing times of $0\mathrm{.}5$ hour? What effects will this have on performance? Do your results agree or disagree with the statement An hour saved at a non$-$bottleneck is a mirage $($i$.$e$.,$ of no value$)?$
