Re: sensitivity analysis (vensim)

Thanks, guys!

However, I have another problem. The graphs of the sensitivity analysis were different and did not appear those indicators of sensitivity 50%, 57%, 95% and 100%.
I have annexed!

sensitivity analysis (vensim)

Hi, guys

I have this difficulty.
I am using the vensim DSS, and I plan to do sensitivity analysis. I can do this in the Monte Carlo function, but when I try generate the graph, I can not, that is, the sensitivity analysis button in the vensim does not appear.
What can it be?

Best regards,

Re: I plot the chart but the line does not appear

I've been able to solve the problem. Problem of standardization of the comma.

Re: I plot the chart but the line does not appear

I modified the comma in the numbers of the irrigation database and got the graph with the row / table with values. However, it did not add up to the urban demand, ie the water demand graph is only with the irrigation data.

Re: How to put excel database in variables?

Could I put my historical data using the "with lookup" command, instead of importing a database?

My data range from 2005 to 2015. They are in a monthly range, but could be placed annually.

What do you think?

Re: How to put excel database in variables?

Another question. The only way to put historical data is by importing data or can put directly into the variable?

Thanks for the answers,
