Queue calculator
Server utilisation is and the total traffic is Erlangs. Assuming the system has exponential interarrival and service times:
- The mean response time (waiting plus servicing) will be s.
- The mean queue length will be .
- The probability of an arrival being queued (Erlang C), is .
- If arrivals that cannot be serviced immediately were lost instead of queued, the probability of loss (Erlang B) would be .
