public class QueueNodeParam extends ServiceNodeParam
Parameter container for queue nodes in queueing networks.

This class extends ServiceNodeParam to add queue-specific parameters, particularly for polling scheduling strategies. Queue nodes may use polling disciplines (gated, exhaustive, or k-limited) with associated switchover times between job classes.

  • Field Details

    • pollingType

      public PollingType pollingType
      Polling type for queues with polling scheduling strategy.

      Specifies the polling discipline: GATED, EXHAUSTIVE, or KLIMITED.

    • pollingPar

      public Integer pollingPar
      K parameter for K-LIMITED polling.

      Specifies the maximum number of jobs to serve per polling cycle.

    • switchoverTime

      public Map<JobClass,Distribution> switchoverTime
      Switchover time distributions by job class for polling servers.

      Defines the time distribution for switching between job classes.

    • setupTime

      public Map<JobClass,Distribution> setupTime
      Setup (cold-start) time distributions by job class.

      Populated from Queue.setDelayOff, as in MATLAB refreshLocalVars.m. Always paired with delayoffTime.

    • delayoffTime

      public Map<JobClass,Distribution> delayoffTime
      Delay-off (teardown) time distributions by job class.

      Populated from Queue.setDelayOff, as in MATLAB refreshLocalVars.m. Always paired with setupTime.

    • pollinfo

      public Polling.Info pollinfo
      Memoized derived description of the polling controller (server position, switchover phase-type, visit budget) for a POLLING queue.

      Built on demand by State.Polling.info, which is read once per state per synchronization while the CTMC generator is built; rebuilding it per call is orders of magnitude slower than the analysis itself.

    • swapGraph

      public Matrix swapGraph
      Pass-and-swap (PAS) class compatibility/swap graph (nclasses x nclasses).

    • svcRateFun

      public SerializableFunction<Matrix,Double> svcRateFun
      Pass-and-swap (PAS) total service rate function mu(c) of the ordered state.

  • Constructor Details

    • QueueNodeParam

      public QueueNodeParam()
      Constructs an empty QueueNodeParam with initialized parameter maps.

  • Method Details

    • isEmpty

      public boolean isEmpty()
      Checks if this queue parameter container is empty.
      Overrides:
      isEmpty in class ServiceNodeParam
      Returns:
      true if no parameters are specified, false otherwise
