    Hi,
    i tried the what-if on a open model, changing the arrival rate. It works , and at the end of the simulations the results are shown.
    The requested number of runs are all executed or the simulation never end the last model? It may be that with some values of the controlled parameter the model saturate?
    We need more info. Could you send us the file of your model or at least the parameters you used?
    We need also info on the operating system of your computer (including version, like windows 7, Ubuntu xxx, ...). Did you use the last version of JMT?

    Hi,
    Am using JMT 0.9.1 on windows 7 operating system
    in the model am trying to set the mean value of exponential service rate of the three queues in the pool to 0.001, though the simulation window perform all the steps and just freeze when it reaches 100% of the simulation and the result window never shows up
    note: if am using the default mean value (1) with the same rest of configuration the result window appears normally.
    Thank you.

      Hi Ali,
      I try to understand your data.
      Just a preliminary comment: pay attention because sometimes the results window is shown in the background, below the other windows, so you can not see it directly. You should search for it changing the order of the windows.
      You say: exponential service rate of the three queues in the pool to 0.001> That means an average service TIME of 1000 (the inverse of the RATE)! In this case the queue is in super-saturation with the default arrival rate of 1!
      If you want to say that 0.001 is the mean service TIME , then, assuming that you have three queue in parallel and the load is splitted evenly among them, the utilization of each station is 0.333 x 0.001, so very small, and far from the saturation. Now, you do not mention the values of the control parameter (I assume that you selected the arrival rate) but if the "what-if" is executed it means that all the models (including the one with the last value, the bigger) are not in saturation and thus you should see the results window (may be below the other windows).
      Regards
      giuseppe

    I tried again but the same problem occurs there is no result window after the simulation reaches 100% ...
    yes, your conclusion is correct and i need the results in case of the mean=0.001 of exponential distribution.
    note that am getting the result window if i set the mean=1 with the same other configuration!
    Thank you.

      Hi,
      try this model: a source, exp.arrival rate=1, one queue with mean service time =0.1, one sink. Select the indexes: number of customers, response time, utilization.
      Select the control parameter of the what-if as "arrival rate": from 1 to 10.2 in 10 steps. Then start the simulation. In spite that it is in saturation with the biggest value of arrival rate = 10.2 , the results are shown.
      So you have problems with your model.
      Please, no longer use this way of communication because it is not a bug of JMT. Use the forum to send us the help requests.
      Regards
      giuseppe

    Ok i will try it, i thought it was a bug in my software but apparently the problem in my model.
    Am sorry for any disturb or misunderstanding
    Thank you for your kind support, very appreciated
    My best regards.
