## How do you calculate average number of customers?

Average number of customers or units waiting in line for service. (D-14) L = Lq + λ/µ The average number of customers or units in the system. (D-15) Wq = Lq / λ Average time a customer or unit spends waiting in line for service. (D-16) W = Wq + 1/µ Average time a customer or unit spends in the system.

## What happens if arrival rate is greater than service rate?

If the arrival rate is greater than or equal to the service rate, there is no stationary distribution and the queue will grow without bound. … We can use the fact that the queue length is a geometric random variable with parameter r/m to compute the average number of requests in the system as r/(m-r).

## What is arrival pattern?

Arrival defines the way customers enter the system. Mostly the arrivals are random with random intervals between two adjacent arrivals. Typically the arrival is described by a random distribution of intervals also called Arrival Pattern. … Typically the customer being served is considered not to be in the queue.

## Which is the formula for waiting time in system?

Wait in the system = W = Wq + 1/µ = 24.08 mins. Number in the system = L = λW = 2.408. Proportion of time the server is idle = 1 − ρ = 0.2. Example 3: Consider the following single-server queue: the inter-arrival time has a gamma distribution with a mean of 10 minutes and a variance of 20 min2.
