Question 1. A manager is contemplating making changes to a single-server system that is expected to double the service rate, and still have just one server.

a. Would you intuitively think that doubling the service rate of a single-server system would cut the average waiting time in half?

b. For the sake of analysis, suppose the current system has an arrival rate of 8 costumers per hour and the service rate is 10 customers per hour. If the service rate is doubled, what impact will that have on the average number waiting in line?

c. What are some of the managerial implications of your analysis?

Question 2. A machine cell uses 250 pounds of a certain material each day. Material is transported in vats that hold 25 pounds each. The cycle time for vats is 2.5 hours. The manager has assigned an inefficiency factor of 0.12 to the cell. The plant operates an 8 hour day. How many vats will be used?
