The Pullman Mfg., Inc. three-station work cell illustrated in Figure S7.8 has two machines at station 1 in parallel. (The product needs to go through only one of the two machines before proceeding to Station 2.) The manager, Ms. Hartley, has asked you to evaluate the system if she adds a parallel machine at Station 2.
a. What is the throughput time of the new work cell?
b. What is the bottleneck time of the new work cell?
c. If the firm operates eight hours per day, six days per week, what is the weekly capacity of this work cell?

d. How did the addition of the second machine at Station 2 affect the performance of the work cell from Problem S7.12?
