tut03 - Adding Statistical Output

• Example tut03:
  • queuing system with statistical output
    • current queue length
    • current utilization of the server
    • total throughput time of the entities (waiting time + processing time)
  • model
    • 
  • getting statistical data
    • output nq of queue
    • output n of server + am_utilization component
    • storing times inside entities
• Working with attributes:
  • attributes = internal data fields in an entity with name and value
  • library components for attributes
    • am_adddata adds data fields to the input object
    • am_writedata changes value of an incoming data field, possibly using values from other fields
    • am_readdata outputs value of an attribute of the input entity
    • am_deletedata deletes data fields from the input object
  • getting throughput time
    • am_adddata creates attribute startTime = 0
    • am_writedata sets startTime = get_time()
    • am_writedata1 sets startTime = get_time() - startTime
    • am_readdata outputs startTime
