Question

Boats arrive for fuel and service at a marina docking facility according to a Poisson probability distribution, with a mean of 5 boats per hour. The service times follow an exponential probability distribution, with a mean of 10 boats per hour. Customer waiting time is valued at OMR 40 per hour, and the cost to operate each dock (channel) is OMR 20 per hour. What is the lowest-cost design for the docking facility (i.e. how many service channels should it have)?

Step 1

First, we need to find the arrival rate (λ) and service rate (μ) for the boats. The arrival rate is given as 5 boats per hour, and the service rate is given as 10 boats per hour. So, λ = 5 and μ = 10. Show more…
