Constructor Details

MM1dLogic

public MM1dLogic(double lambda,
 double s,
 int max)

Initializes the queue

Parameters:

lambda - represent the medium of arrival of Poisson process [job/s]

s - represent the medium of the service time of Poisson process [ms]

max - represent the maximum length of the queue
