3.        A manufacturing facility produces two types of a product: Standard and Deluxe. The process flow for both types of production is shown in the following chart. Both types are first processed through steps A1 and A2. The Standard then goes through steps A3 and A4 while the Deluxe is processed through steps A5, A6, and A7. Both types finish at A8. The numbers in parentheses indicate the minutes it takes for that activity to process a single unit.

a)         Which step is the bottleneck for the Standard products? Which step is the bottleneck for the Deluxe products?

b)        What is the capacity (measured as units per hour) of the facility to process the Standard products? What is the capacity to process the Deluxe products?

c)         If 60% of the products are Standard and 40% are Deluxe, what is the average capacity (measured as units per hour) of the facility?

d)        Suppose the actual throughput of the facility is 3.2 units per hour. Again, 60% of the products are Standard and 40% are Deluxe. What is the utilization of each step (A1-A8)?
