jline.examples.java.basic.OpenNHPPModel
public class OpenNHPPModel extends Object
Open queueing network with an NHPP (cyclic) arrival process.

NHPP is a non-homogeneous Poisson process with a piecewise-constant intensity: segment i covers [breakpoints[i], breakpoints[i+1]) and carries rate rates[i]. With cyclic=true the schedule repeats with period breakpoints[n]-breakpoints[0], giving a cyclic Poisson process. Only the LDES simulation engine honours the exact schedule; every analytical solver rejects a model using it via the standard unsupported-feature check.

  • Method Details

    • oqn_nhpp

      public static Network oqn_nhpp()
      Open M/M/1 whose Source uses a cyclic NHPP arrival stream. Rates 2, 8, 4 are held for 3, 1, 2 time units respectively, repeating cyclically, so the breakpoints are cumsum([0, 3, 1, 2]) = [0, 3, 4, 6].
      Returns:
      configured open network with an NHPP arrival process

    • main

      public static void main(String[] args) throws Exception
      Solves the NHPP model with the LDES simulation engine and prints the average performance table.
      Parameters:
      args - command line arguments (not used)
      Throws:
      Exception - if the solver encounters an error
