"Fake" warm-up (initial conditions)

Hi,

In order to keep my model as simple as possible, I am trying to implement a "fake warm-up". A processor with a very long ProcessTime is filled at time zero with the steady-state quantity of FlowItems. Each FlowItem should have its own ProcessTime ranging from almost zero to the steady-state process time.

Process time code:

double InitialContentProcessor = 100;
double ProcessTime = 1000;
double InputCurrent = getinput(current);
if(InputCurrent <= InitialContentProcessor)
{
    ProcessTime = InputCurrent/InitialContentProcessor*ProcessTime;
}
return ProcessTime;

The problem is that (it looks like) 50 FlowItems enter the processor at them same time, before calling the processors' ProcessTime function - therefore the calculated process time is wrong.

Does anyone have a simple solution to know which FlowItem entered first, second... ?

Thanks!

By closing the input of the processor in the OnEntry trigger, and then reopening after having calculated the process time in the ProcessTime function of the processor, the process times are right.

I don't know whether it is a good idea to open the output in a ProcessTime function, but for the moment it works. If somebody has a cleaner solution, it is still very welcome!
