Method Details

input

public boolean input(int[] t,
 double[][][] s,
 double[][] v)

Initializes the solver with the system parameters. It must be called before trying to solve the model.

Parameters:

t - array of the types (LD or LI) of service centers

s - matrix of service times of the service centers

v - array of visits to the service centers

Returns:

True if the operation is 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

validateMaxSamples

public static Integer validateMaxSamples(String maxSamples)

validatePrecision

public static Integer validatePrecision(String precision)

hasSufficientProcessingCapacity

public boolean 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.
Must be implemented to create a multi class model solver.
WARNING: This method should be called before solving the system.

Specified by:

hasSufficientProcessingCapacity in class SolverMulti

Returns:

true if sufficient capacity exists for the given workload, false otherwise
