Sensitivity Tests

Hi,

I try to make a sensitivity simulation for a model that is similar to the customer-model of the VENSIM tutorial. How does it exactly work and which variables are supposed to be changed?
Do I only have to set a MIN/MAX -range for the constants of the model?

Thanks for your help!!

Graphs and subscripts!!

Hi,

I have a model with subscripts. When I do a normal simulation the graph always shows the curves for all subscripts. How is it possible to show the graph only for a single subscript??

Kind regards,

trend technology

Hi J.J., in this case by "technology" it is meant the awareness of brand- specific technology images. The graduation of awareness could vary on a scale from 1-10. I took the actual technology awareness from questionings and statistics. I estimated trends which I calculated with earlier tim...

Word of Mouth advertising

Hello,

actually, I´m building a model for "Word of Mouth advertising" with VENSIM.
Has anybody already created such a model? And: Does anybody have some information about contact rates and adoption rates caused by WoM advertising?

Thanks a lot for your help!

Sincerely,

Run a GAME!!?? -->Test Inputs??

Hi!! I have a model for that describes the influences on the contact rate. One of these influences should be the advertising spending. Now I tried to define the variable as "Gaming"-variable, so that one coul simulate the influence of a changing advertising budget. When I click the button ...

Hi, Currently I am trying to build up a model to represent trend developments of several product attributes, p.e. the product quality or technology trends. I took the initial values from questionings and statistics. There are also information about the trend direction. My question is, how to transfo...

Import Subscripts?

Hello,

is it possible to import subscripts from an existing VENSIM Model. I am building a new model and it would be much more easier to import the subscripts from a model built before!

Thanks for your help!!!!

kind regards
