Consider the assembly line below. The process makes products in batches. The two blow molding machines run in parallel, such that each batch only needs to go through one of the two blow molding processes. After that, each batch needs to go through one of the assembly operations that run in parallel. The units are packaged in the final station and made ready for shipment after quality control.

a$)$ What is the throughput time of the process?

b$)$ Which operation is the bottleneck and what is the bottleneck time $($flow time$)?$

c$)$ Explain the difference between the bottleneck time and the throughput time in a short paragraph.

d$)$ Find the hourly capacity of the process and calculate the utilization of each fabrication operation.
