Method Details

input

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

Description copied from class: Solver

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

Overrides:

input in class Solver

Parameters:

n - array of n of service centers.

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

s - matrix of service time 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: Solver

Must be implemented to create a single class model solver.

Specified by:

solve in class Solver

hasSufficientProcessingCapacity

public boolean hasSufficientProcessingCapacity()

Description copied from class: Solver

A system is said to have sufficient capacity to process a given load lambda if no service center is saturated as a result of such a load.
WARNING: This method should be called before solving the system.

Specified by:

hasSufficientProcessingCapacity in class Solver

Returns:

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