This is a queuing theory question,. The average arrival rate, λ, is the average number of arrivals per unit of time (minute, hour, day week, etc.); the average time between two consecutive arrivals is 1 / λ. If I told you that λ= 5 patients per hour, how many minutes would there be between two consecutive arrivals on average? How did you determine your answer?

Answer #1

The arrival rate is 5 patients per hour. That means on average 5 patients arrive per hour or 60 minutes.

Average time between two consecutive arrival = 60 minutes/arrival rate = 60 / 5 = 12 minutes

    Consider the M/M/1/GD/∞/∞ queuing system where λ and μ are the arrival and server rate, respectively. Suppose customers arrive according to a rate given by λ = 12 customers per hour and that service time is exponential with a mean equal to 3 minutes. Suppose the arrival rate is increased by 20%. Determine the change in the average number of customers in the system and the average time a customer spends in the system.

    During the COVID-19 pandemic, the hospital emergency department at a very busy hospital receives, on average, 23.6 patient per day. The standard deviation of inter-arrival time between two consecutive patients arriving is 6.9 minutes. What is the coefficient of variation for the inter-arrival times (times between two consecutive arrivals) for patients arriving (received at) at the hospital’s emergency department? Note that, the emergency service of this hospital is open 24/7, and one day is equivalent to 24 hours.

    Consider a simple queuing system in which customers arrive randomly such that the time between successive arrivals is exponentially distributed with a rate parameter l = 2.8 per minute. The service time, that is the time it takes to serve each customer is also Exponentially distributed with a rate parameter m = 3 per minute. Create a Matlab simulation to model the above queuing system by randomly sampling time between arrivals and service times from the Exponential Distribution. If a...
