Method Detail

• extractFJParams

   final static Pair<List<FJArrival>, List<FJService>> extractFJParams(NetworkStruct sn, FJInfo fjInfo)

  Extract Fork-Join parameters from network structure

  Extracts arrival and service processes for each class from the network, converting LINE distributions to FJ_codes format. Supports:

  • Exponential arrivals (single-phase MAP)

  • General MAP arrivals (multi-phase)

  • Exponential service (single-phase PH)

  • General PH/APH/Erlang/HyperExp/Coxian service (multi-phase)

  Parameters:

  sn - Network structure

  fjInfo - Fork-Join topology information

  Returns:

  Pair of (arrivals per class, services per class)

• convertToFJArrival

   final static FJArrival convertToFJArrival(Matrix D0, Matrix D1)

  Convert LINE MAP to FJ arrival format

  Computes the stationary distribution of the underlying Markov chain to determine the correct arrival rate: lambda = pi * D1 * e.

  Parameters:

  D0 - D0 matrix (transitions without arrivals)

  D1 - D1 matrix (transitions with arrivals)

  Returns:

  FJArrival

• convertToFJService

   final static FJService convertToFJService(Matrix S, Matrix s, Matrix tau)

  Convert LINE PH to FJ service format

  Uses the PH initial vector (pie from MAP representation) as the initial probability for phase selection. Mean service rate is computed as mu = 1 / (tau * (-S)^{-1} * e).

  Parameters:

  S - Sub-generator matrix (negative diagonal = phase rates)

  s - Exit rate vector (s = -S * e for absorbing PH)

  tau - Initial probability vector

  Returns:

  FJService

• convertToFJServiceFromProc

   final static FJService convertToFJServiceFromProc(MatrixCell proc)

  Convert LINE process cell {D0, D1} to FJ service format.

  Extracts the sub-generator S=D0, exit rate vector s=-D0e (or D1e), and initial probability vector tau from the MAP/PH representation.

  Parameters:

  proc - MatrixCell containing {D0, D1}

  Returns:

  FJService
