For a single server with Poisson arrival and exponential service time, the arrival rate is 12 per hour. Which one of the following service rates will provide a steady state finite queue length?
-
- 6 per hour
- 10 per hour
- 12 per hour
- 24 per hour
Correct Option: D
For steady state, μ > λ
as λ = 12 customers/hour, we need to select option (d)
