Model Description

We use the M/M/1/k model to exemplify the use of symbolic parameters. We only change the declaration of the exponential rates. For the two exponential events, we declare in the Declaration attribute

Object: Poisson_Source
Declaration=
  Const
    Port: PORT_OUT;
  Param
    Float: pkt_rate;

Object:Server_Queue
Declaration=
  Const
    Integer: QUEUE_SIZE;
    Port: PORT_IN;
  Var
    integer: Queue;
  Param
    Float:service_rate;

We must modify the Initialization attribute of the objects, removing the pkc_rate and service_rate initialization. Figure shows the model.
