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 process

times are deterministic (as in the best case)

(a) What are rb and T0 for this line?

(b) How do rb and T0 change if a second identical machine is added to station 2? What

effects will this have on performance?

(c) How do rb and T0 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?

(d) How do rb and T0 change if a second, identical machine is added to station 1? What

effects will this have on performance?

(e) How do rb and T0 change if the machine at station 1 is speeded up to have average

processing times of 1/2 hour? What effects will this have on performance? Do your

results agree or disagree with the statement "An hour saved at a nonbottleneck is a

mirage (i.e., of no value)"?
