Package jline.solvers.wrappers.lqns.qnsolver

package jline.solvers.wrappers.lqns.qnsolver
The qnsolver engine behind the qns methods of SolverLQNS on a flat Network.

qnsolver is the product-form MVA tool of the LQNS distribution. The model is written as a JMVA document, qnsolver is run on it, and its results are read back. A closed non-product-form Network does not come here: SolverLQNS converts it with QN2LQN and solves it with lqns. Key classes: - Solver_qns_analyzer: analyzer, called from SolverLQNS - Solver_qns: core handler that writes the JMVA document and runs qnsolver Multiserver approximations, selected by the method qns.NAME: - conway: Conway (1989), extending the multinomial all-servers-busy probability of de Souza e Silva and Muntz (Perform. Eval. 7(3), 1987) - rolia: Rolia (PhD thesis, Toronto, 1992) as used in the method of layers (Rolia and Sevcik, IEEE TSE 21(8), 1995), in the per-class Rolia-Franks form of Franks (PhD thesis, Carleton, 1999) - zhou: arrival-theorem binomial (AB) approximation, S. Zhou (M.A.Sc. thesis, Carleton, 2021) and Zhou and Woodside (ICPE Companion 2022) - suri: Suri, Sahu and Vernon (IERC 2007) - reiser: Reiser and Lavenberg (J. ACM 27(2), 1980) load-dependent MVA, see also Reiser (Perform. Eval. 1, 1981) - schmidt: Schmidt (Perform. Eval. 29(4), 1997) The qnsolver executable must be available in the system PATH.
