Detailed Description

SolverJMT: the Java Modelling Tools client, which also answers a transient, a response-time law, a state probability and a trajectory.

IT IS NOT A BARE LINE_DECLARE_SOLVER, and the difference is the point: the macro exposes averages alone, so a program holding a SolverJMT could reach getAvgTable and nothing else while jmt_logs.h implemented all four of these and line-cli -s jmt reached none of them either.

EVERY ONE OF THEM IS READ OFF A LOGGED RUN, so each is a jsim answer whatever --method asked for: JMVA computes means from a product form and logs no trajectory at all.

Member Function Documentation

◆ cdf_respt()

std::vector< std::vector< CdfCurve > > line::SolverJMT::cdf_respt ( )

getCdfRespT(): the EMPIRICAL response-time CDF per (station, class).

Definition at line 692 of file solver_facade.cpp.

References line::qn::Network< T >::get_struct(), line::jmt::jmt_get_cdf_resp_t(), line::NetworkSolver::model_, and line::NetworkSolver::opts_.

◆ prob_aggr()

double line::SolverJMT::prob_aggr	(	std::size_t	node,
		const std::vector< double > &	state )

getProbAggr(node, state): the time the declared state is held for.

Definition at line 737 of file solver_facade.cpp.

References line::qn::Network< T >::get_struct(), line::InputError::InputError(), line::jmt::jmt_prob_aggr(), line::NetworkSolver::model_, line::NetworkSolver::opts_, and line::jmt::JmtProbAggr::station.

◆ sample()

SamplePath line::SolverJMT::sample	(	std::size_t	events = 0,
		std::size_t	node = 0 )

sampleSysAggr(events), or sampleAggr(node, events) when node is given: one logged trajectory.

events TRUNCATES, it does not stop the run: JMT's maxEvents is global and cannot be asked for a count at one node, so what comes back is a prefix of the run the engine produced. Zero returns all of it.

Definition at line 746 of file solver_facade.cpp.

References line::qn::Network< T >::get_struct(), line::InputError::InputError(), line::jmt::jmt_sample_aggr(), line::jmt::jmt_sample_sys_aggr(), line::SamplePath::label, line::NetworkSolver::model_, line::NetworkSolver::opts_, line::SamplePath::state, and line::SamplePath::t.

◆ tran_avg()

TranAvg line::SolverJMT::tran_avg ( )

getTranAvg(): E[N](t), averaged over options.config.replications (SolverOptions::replications, default 10) independent replications under method default; an explicit jsim is one run.

A FINITE HORIZON IS REQUIRED (options.timespan): a transient mean over an unstated horizon is not a quantity, and it is also what makes the replications' event grids commensurable.

Definition at line 717 of file solver_facade.cpp.

References line::qn::Network< T >::get_struct(), line::jmt::jmt_transient_replications(), line::TranAvg::label, line::NetworkSolver::model_, line::NetworkSolver::opts_, line::jmt::JmtReplication< T >::QNt, line::TranAvg::QNt, line::jmt::JmtReplication< T >::t, and line::TranAvg::t.
