public class SolverBA
extends NetworkSolver

SolverBA is the dedicated bound-analysis solver for closed queueing networks.

Unlike SolverMVA (point estimates), each method returns an optimistic (.upper) or pessimistic (.lower) throughput/queue-length bound; the two sides of a family bracket the exact solution. Bounds need only demands and populations, so the feature set is narrow (closed product-form-parameterized models). Method families:

• Noniterative: aba, bjb, pb, gb, sb, mwba (Majumdar-Woodside).
• Hierarchical: pbh (Eager-Sevcik), pbk/bjbk (iterative PB(k)/BJB(k)), cbh (Dowdy), ssd (Suri-Dallery multiserver), cub (Kerola composite upper) with mbjb (multiclass BJB lower), sib (Srinivasan), ldbcmp (Anselmi-Cremonesi LD-BCMP lower).
• QRF: qrf.* (Quadratic Reduction Framework, LP-based, PH service), with aliases qr -> qrf.mmi and lr -> qrf.mmi.linear.

runAnalyzer

public void runAnalyzer()
                 throws IllegalAccessException

Description copied from class: Solver
