  MixedModel()

Method Detail

• mqn_basic

   static Network mqn_basic()

  Simple mixed open/closed network with delay and PS queue.

  Features: - One closed class (2 jobs) and one open class - Delay node with Erlang service for closed class, HyperExp for open - PS queue shared by both classes with different service distributions - Closed class circulates between delay and queue - Open class flows: Source → Delay → Queue → Sink

  Returns:

  configured mixed network model

• mqn_multiserver_ps

   static Network mqn_multiserver_ps()

  Complex mixed network with five PS queues and different server counts.

  Features: - One closed class (3 jobs) and one open class - Five PS queues with 1, 2, 3, 4, 5 servers respectively - Closed class cycles through Queue1→Queue2→Queue3→Queue4→Queue1 - Open class follows Queue1→Queue2→Queue3→Queue5→Sink - Different service rates optimized for server counts

  Returns:

  configured mixed network model

• mqn_multiserver_fcfs

   static Network mqn_multiserver_fcfs()

  Mixed network similar to example 2 but with FCFS scheduling.

  Features: - Same topology as mqn_multiserver_ps() but FCFS queues - One closed class (3 jobs) and one open class - Five FCFS queues with varying server counts (1-5) - Demonstrates scheduling strategy differences in mixed networks - Identical service rates and routing patterns

  Returns:

  configured mixed network model

• mqn_singleserver_fcfs

   static Network mqn_singleserver_fcfs()

  Mixed network with large closed class population and APH arrivals.

  Features: - Large closed class with 100 jobs circulating through 4 FCFS queues - Open class with APH (Acyclic Phase-type) arrival process - High variability arrivals (SCV = 64.0) for bursty traffic - Open class exits after Queue3, closed class cycles through all 4 - Demonstrates heavy traffic mixed system behavior

  Returns:

  configured mixed network model

• mqn_singleserver_ps

   static Network mqn_singleserver_ps()

  Mixed PS network with large closed population and simplified open routing.

  Features: - Large closed class (100 jobs) with 4 PS queues in cycle - Open class with exponential arrivals (rate 0.3) - Open class follows shortened path: Queue1→Queue2→Queue3→Sink - PS scheduling for all queues - Demonstrates processor sharing in mixed environments

  Returns:

  configured mixed network model

• main

   static void main(Array<String> args)

  Main method for testing and demonstrating mixed model examples.

  Currently configured to run mqn_singleserver_fcfs() and solve it using the NC (Normalizing Constant) solver.

  Parameters:

  args - command line arguments (not used)
