Publishing a vensim model

Hi I have run the model for three different scenarios (with changing one parameter of the system), so Vensim plots the three different scenarios in one graph. Now, I need to send the vensim model to someone else and show the graphs, I want him to see the graph of three scenarios in one run. How can ...

Re: different distribution for each subscript

Thanks for your reply.
It means if I have 10 variables like this ( with different distributions for each subscript) I need to define about 50 extra variables in the model, right?

Re: different distribution for each subscript

thanks for your reply, you are right.
Then I have to define 5 new constants to the model and subscript them while I was thinking that maybe I can define it for example like this:
for three subscript:
RANDOM NORMAL(80,90,100,10,1),RANDOM NORMAL(82,95,100,10,1),RANDOM NORMAL(70,95,100,15,1)

different distribution for each subscript

Hi

My question is, can I have different distribution for each of my subscript in vensim? the problem is I have three subscript and I want to define the price for each of them as random normal with different mean and std; however it causes an error. could you please guide me?

Cheers
Samira

Re: optimization in vensim based on time

Sorry, I have attached them.
Thanks for your time and consideration.

For subscripts I selected them all in subscript control. Is it what you mean?

Re: optimization in vensim based on time

Hi Tomfid Thanks for your reply. I couldn't solve the problem even I made it worse, I used subscripts for my decision variables and now the optimization is not working anymore. Could you please have a look to my sample model( I tried to make a simple one just to learn Vensim through it). it would be...

optimization in vensim based on time

Greetings! I would like to know is there any chance in vensim optimization to have the result during time? for example I made a simple model to learn vensim optimization. in this model I have three suppliers which I want to allocate order amount to them without using (ALLOC function ). now I want to...

Re: vensim to matlab

Hi
Yes and thanks for your help.
Matlabx32 installed and finally could load vendll32 there.Now I am figuring out how to call my Vensim file and special variables in the model.

Re: vensim to matlab

Hi

What if I upgrade my Vensim to 64 bit? Do you think it would work and can I call the dll from Matlab 64 bit?

Re: vensim to matlab

Yes I have tried the code for matlab which comes with vensim, however the first step ( calling vensim dll) is not working.
do you have any idea to have bridge process or getting rid of HWnd error.

Re:

Finaly I could load vendll32. Now I load this model: str=['SPECIAL>LOADMODEL|',test,'.vpm']; lp=libpointer('voidPtr',[int8(str) 0]); calllib('vendll32','vensim_command',lp); How can I see the result of my model in matlab or the amount of variable thet I defined in vensim? You mean by installing XP,...
