Method Details

qsys_mmck

public static Qsys_mmck.Result qsys_mmck(double lambda,
 double mu,
 int c,
 int K)

Analyzes an M/M/c/K queueing system exactly. Stationary distribution (truncated Erlang form): with a = lambda/mu and rho = a/c, p_n prop a^n/n! for n <= c and a^c/c! * rho^(n-c) for c <= n <= K, normalized over the K+1 levels.

Parameters:

lambda - Poisson arrival rate (> 0)

mu - Per-server exponential service rate (> 0)

c - Number of servers (>= 1)

K - System capacity, total jobs allowed (K >= c)

Returns:

Result with mean counts, times, utilization, throughput and loss
