1. Consider a manufacturing line of four workstations and four machines. The machine in Workstation 2 has an average process time of 4 hours per job. The other machines are identical with an average process time of 2 hours. Answer the following questions with the assumption that the process times are deterministic and there is no variation: (a) What are the ro and To for the described manufacturing line? To ro (b) Assume that we add an identical second machine to Workstation 2. What is the value of r and To? To ro: In maximum three sentences, explain the effect of adding that machine on the performance of the line: (c) Assume that the single machine in Workstation 2 is speeded up. The new process time is 2 hours. What is the value of ro and To? T: : In maximum three sentences, explain the effect of that adjustment on the performance of the line: (d) What will be the value of ro and To if we add an identical second machine to Workstation 1? To: In maximum sentences, explain the effect of adding that machine on the performance of the line: (e) How about speeding up the single machine in Workstation 1 twice as fast? To In maximum three sentences, explain the effect of that adjustment on the performance of the line:
