[Dsol-java] support for dynamic processes in process interaction formalism

[Hendrik B. <bi...@em...>]

Hi all,

is it possible to develop a model in the process interaction formalism 
which describes a dynamic sequence of actions? For example, let's say we 
have a manufacturing job which has to pass machines 1-2-3-4. Now I would 
like to implement a rule which changes this sequence, e.g. to 1-2-4 if 
the queue at machine 3 is longer than 2. I tried to put only 1-2 in the 
process method of the manufacturing job and then schedule a SimEvent 
with the decision method. In pseudo code it looks like this:

process(){
  passMachine_1();
  passMachine_2();
  simulator.scheduleEvent(new SimEvent(now, this, this, decisionMethod)
}

decisionMethod(){
  if(queue.length > 2){
    passMachine_4();
  }
  else{
    passMachine_3();
    passMachine_4();
  }
}

But it is obviously not possible to put parts of the process in another 
method, as this involves the suspend method, which should not be invoked 
directly. So that's where I'm stuck now. Is there a solution within the 
process interaction formalism, and if not, which formalism shoud I use?

Thanks,

Hendrik
