Package org.oristool.models.stpn.steady

Class RegSteadyState

java.lang.Object
org.oristool.models.stpn.steady.RegSteadyState
All Implemented Interfaces:
Engine<PetriNet,Marking,SteadyStateSolution<Marking>>
public abstract class RegSteadyState extends Object implements Engine<PetriNet,Marking,SteadyStateSolution<Marking>>
Steady-state analysis of STPNs using trees of stochastic state classes between regenerations.

  • Method Details

    • stopOn

      public abstract Supplier<StopCriterion> stopOn()
      Returns the supplier of local stop criterion instances used by this analysis. It can be used to avoid the expansion of some state classes, as if their states were absorbing.

      A stop criterion instance is generated for each run.

      By default, an always-false local stop criterion is used.

      Returns:
      the supplier of local stop criterion

    • monitor

      public abstract AnalysisMonitor monitor()
      Returns the monitor used by this analysis. It is used to stop the analysis early and to notify messages to the user.

      By default, an always-false, message-discarding monitor is used.

      Returns:
      the monitor used by this analysis

    • logger

      public abstract AnalysisLogger logger()
      Returns the logger used by this analysis. It is used to print progress information.

      By default, logs are discarded.

      Returns:
      the logger used by this analysis

    • builder

      public static RegSteadyState.Builder builder()
      Creates a builder for analysis configurations (with default values).
      Returns:
      a builder of TimedAnalysis instances.

    • compute

      public SteadyStateSolution<Marking> compute(PetriNet pn, Marking m)
      Runs this analysis on a given Petri net from an initial marking.
      Specified by:
      compute in interface Engine<PetriNet,Marking,SteadyStateSolution<Marking>>
      Parameters:
      pn - the input Petri net
      m - the initial marking
      Returns:
      a succession graph encoding the state class graph
      Throws:
      IllegalArgumentException - if the analysis is not applicable to the input Petri net

    • canAnalyze

      public boolean canAnalyze(PetriNet pn, ValidationMessageCollector c)
      Description copied from interface: Engine
      Checks if the analysis can be applied to the given model.

      Problems are collected in a ValidationMessageCollector.

      Specified by:
      canAnalyze in interface Engine<PetriNet,Marking,SteadyStateSolution<Marking>>
      Parameters:
      pn - input model (such as a Petri net)
      c - collector of error messages
      Returns:
      true if the analysis can be applied to the given model
