fin.queuing-MMc-server-utilisation Calculator
Calculates M/M/c queue performance metrics including utilisation, average queue length, and average wait time for c parallel servers. M/M/c queuing shows the dramatic improvement from adding a second server — a single-server queue at 80% utilisation has 4× the waiting time of a two-server queue.
Inputs
Lambda Per Hr
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Mu Per Hr
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
C Servers
Count of items or occurrences.
Results
server utilisation ρ
The value at the specified point or condition.
avg queue length Lq
The computed linear length.
avg waiting time Wq (min)
The computed duration or time value.
probability system empty P₀
Reference formula or conversion factor shown for context.
M/M/c model: stable if λ < c·μ
The most frequently occurring value.
server recommendation
Suggested action or value based on the computed results and applicable best-practice guidelines.
