We have a call center where the inter-arrival time of calls is 10 seconds on average and the service rate is 1 call per minute.
We have to find the minimum number of representatives required so that the queue is stable.
We can start by expressing the arrival rate of calls as:
[tex]\lambda=\frac{1}{\#\text{calls per minute}}=\frac{1}{6\min }[/tex]The service rate is:
[tex]\mu=1\frac{1}{\min }[/tex]For stability
