Package solvers

package solvers

Solution algorithms of JMVA. JMVA solves open, closed and mixed product form queueing networks: open models with the classical queueing network algorithms and closed models with the exact algorithms MVA (Mean Value Analysis, in a stabilized version for load dependent stations), RECAL (Recursion by Chain Algorithm), MoM (Method of Moments), CoMoM (Class Oriented Method of Moments) and TreeMVA, as well as the approximate AMVA algorithms Chow, Bard-Schweitzer, Linearizer, DeSouza-Muntz Linearizer and AQL (Aggregate Queue Length).
