Q. Lower- Colorado River Authority (LCRA) has been studying congestion at boat-launching ramp near Mansfield Dam. On weekends, arrival rate averages 5 boaters per hour, Poisson distributed. average time to launch or retrieve a boat is 10 minutes, with negative exp1ntial distribution. Assume that only 1 boat can be launched or retrieved at a time.
a.) LCRA plans to add another ramp when average turnaround time exceeds 90 minutes. At illustrate what average arrival rate per hour should LCRA begin to consider adding another ramp?
b.) If re were room to park only 2 boats at top of ramp in preparation for launching, explain how often an arrival would find out insufficient parking space?
Q. Explain why would you need to use linear programming to make a decision and not some or financial tool?
