147 seconds per customer so only 25.5 cars can be served. Rock View Restaurant wants to
increase its drive-through capacity to 60 cars per hour by forming a multi-window line.
i.
Draw the precedence diagram to represent the process at Rock View Restaurant.
ii.
Calculate the cycle time in seconds.
iii.
Calculate the minimum number of windows that Rock View Restaurant will need to
serve 60 cars per hour.
question:
What is the amount of increase in profit for each Machine Hour added and what is the maximum number of yards that can be added for this amount of profit increase?
