Question

A single server model with infinite calling population, first-come, first-served queue discipline, Poisson arrival rate and exponential service time has an arrival rate of 210 customers and a service rate of 270 customers per eight hour day. The average number of customers in the system is

Answer 1

3.5 customers

Step-by-step explanation:

The computation of the average number of customers in the system is shown below:

= (Arrival rate) ÷ (Service rate - arrival rate)

= (210 customers) ÷ (270 customers - 210 customers)

= (210 customers) ÷ (60 customer)

= 3.5 customers

We simply apply the average number of customers formula so that the correct value can come
