Method Details

qsys_gg1

public static HashMap<String,Object> qsys_gg1(double lambda,
 double mu,
 double ca2,
 double cs2)

G/G/1 queue analysis (general arrivals and service).

Uses exact methods for the special cases (M/M/1, M/G/1, G/M/1) and the Allen-Cunneen approximation for the general case. In the G/M/1 case the interarrival-time distribution is fitted from (lambda, ca2) by a two-moment renewal process (H2 with balanced means for ca2>1, mixed Erlang for ca2<1) and sigma is the root of sigma = A*(mu*(1-sigma)), with A* the interarrival-time LST.

Parameters:

lambda - arrival rate

mu - service rate

ca2 - squared coefficient of variation of inter-arrival time

cs2 - squared coefficient of variation of service time

Returns:

HashMap containing L, Lq, W, Wq, p0
