• pfqn_schmidt

   final static Ret.pfqnAMVASchmidt pfqn_schmidt(Matrix rates, Matrix N, Matrix S, Matrix v, List<SchedStrategy> sched)

  Schmidt MVA algorithm for multi-class FCFS queueing networks.

  Computes performance metrics for product-form queueing networks using the Schmidt MVA algorithm. This is an exact algorithm for closed queueing networks with class-dependent FCFS scheduling.

  Reference: R. Schmidt, "An approximate MVA algorithm for exponential, class-dependent multiple server stations," Performance Evaluation, vol. 29, no. 4, pp. 245-254, 1997.

  Parameters:

  rates - Service rate matrix (M x R) - rates per station and class

  N - Population vector (1 x R)

  S - Number of servers at each station (M x 1)

  v - Visit ratio matrix (M x R)

  sched - List of scheduling strategies for each station

  Returns:

  pfqnAMVASchmidt result containing throughput, queue length, utilization, response time, and probabilities

• pfqn_schmidt_ext

   final static Ret.pfqnAMVASchmidt pfqn_schmidt_ext(Matrix rates, Matrix N, Matrix S, Matrix v, List<SchedStrategy> sched)

  Extended Schmidt MVA algorithm with queue-aware alpha corrections.

  A queue-aware version of the Schmidt algorithm that precomputes alpha values for improved accuracy in networks with class-dependent FCFS scheduling.

  Parameters:

  rates - Service rate matrix (M x R)

  N - Population vector (1 x R)

  S - Number of servers at each station (M x 1)

  v - Visit ratio matrix (M x R)

  sched - List of scheduling strategies for each station

  Returns:

  pfqnAMVASchmidt result
