Method Details

input

public boolean input(String[] n,
 int[] t,
 double[][][] s,
 double[][] v,
 double[] classData,
 int[] classType,
 int[] p)

initializes the solver with the system parameters.

Parameters:

n - array of names of service centers.

t - array of the types (LD, LI, Delay, PRS, HOL) of service centers.

s - matrix of service time of the service centers.

v - matrix of visits to the service centers.

classData - array describing the classes: each element can be either an arrival rate (for open classes) or a population (for closed ones), according to the class type

classType - array of class types (open or closed)

p - array of priorities of the classes.

Returns:

true if the operation has been completed with success

solve

public void solve()

Description copied from class: SolverMulti

Must be implemented to create a multi class model solver.

Specified by:

solve in class SolverMulti

hasSufficientProcessingCapacity

Description copied from class: SolverMulti

A system is said to have sufficient capacity to process a given load lambda if no service center is saturated as a result of the combined loads of all the classes.
