Ventana software support forum

thanks that worked.

thanks,I wonder if you could tell me where it is.
Because I saw the help but did not find my answer
thx

Hi
when I compare DelayI and smooth, I do not get a different answer, they are the same, what is the difference?
thx

thanks a lot

and if it is possible send me an example file
thx

thx for replies, is it possible in PLE version?

Hi I have 6 products in my production line and I want to have different flows and stocks for each of them, I do not want to draw six flow variables and etc. is it possible n Vensim to have one flow variable with different value like index or something? that whenever you say index i, it understand it...

I think there should be a kind of help tool that when the mouse cursor is placed on anything, a quick help emerges.

thanks
I am really delighted to get acquainted with this site and its administers specially Tomfid who always helps me.

thx
it was a good start, By the way is there any way in vensim that can help us distinguish variable? for example name the constant one? how many constant are there? how many stock and etc.
best wishes

I meant as you can see in the picture, the behavior and structure of the actual quality is clear, suppose the formula of its inflow and outflow is not clear (for actual quality), can you suggest anything (inflow or outflow) that produce actual quality behavior?

Hi
As we know, stock variable is the integral of flow, if there is a stock with zero slope diagram, what could be the flow anyway?
I meant the Quality diagram in the attached file
best wishes

thx alot
that works

Hi
First I want to if there is any paper or stuff like that which is about dimension in SD. Second I saw a simple example but I did not understand the why the unit of the fraction is that, and when I use it in Vensim as it is obvious I face unit error.
I would be thankful if you help me.

thanks for all answers I got it
Best wishes

Hi,
When a simple model is created in Vensim, with just one stock and inflow and outflow.
When we want to insert the formula of the given stock, in the part of variables you find the inflow name, the outflow and stock name. why is there the stock variable name? it does not make sense.
thx

thanks a million
Ive got it now

thanks, but I did not get the point, especially that the above sentence is some how against the lower one.
Regards

Hello,
I saw in some of the references that SD is not very useful for predicting, but I do not know the reason. I wonder if anybody can help me

thx
They were really really helpful
Best wishes

yes tomfid, this is exactly the problem that Ive had, I do not want to make it discrete as you said, that is fo Arena and discrete event simulation, let me put it this way there is something like Aging chain that parts are flowing in the production line i.e designing pre production and etc. in one s...

Hi everyone,
I have a question, when we want to model a production line and the parts are gathered in work in process stock, how can they be inspected whether their quality are accepted or not? by just "if then else" or something else?
Suppose there is a quality level
thx
