Re: Random Function and Subscript
I'm still not sure what the goal is. Can you restate? So far it sounds like: - each unit generates a random amount - the sum of generation across all the units = demand I could imagine other constraints, for example that some units are bigger than others. It's okay if the some units having bigger v...

Re: Random Function and Subscript
It sounds like you want total generation to be a fixed number, allocated among all the sources with some random noise in the individual sizes or shares. Normalization is a common way to do this: prelim unit size[x] = 500 + RANDOM UNIFORM(-100,100,0) prelim total size = SUM(prelim unit size[x!]) nor...

Re: Random Function and Subscript
It would help if you upload the model (it will save us guessing about what you are doing). How do you split total generation into the four types? And then how is the total coal generation split between the 14 coal elements? We do have some allocation functions, but it would be easier if you upload ...

Thanks so much, Admin. I'll try to do it, and hope it works well with my model.
Thanks once again

Re: Combine output
Thanks a lot, Tom & Admin.
Tried the solutions suggested, and i get to do what exactly i want to do.
But now i encountered another problem which is, an error put as "Arguments out of range in VECTOR SORT_ORDER".
What does that means?

Re: Combine output
It might have been much easier to do this with subscripts, all the structures look identical so subscripts would have been perfect. If you upload the model, it should be easy to demonstrate how to do this. But i've learnt that we can only have up to 8 subscripts. Please enlight me on this, Admin. H...

Hello all!
I'm back with another confusion in my life with Vensim
How do i combine all outputs into one matrix/under one variable? But i do not want it to be accummulated.
Please send me some help. Thanks in advance.

Different between NPV, NPVE, and Net Present Value function?
Hello everyone,
I have one simple yet confusing (at least for me) question regarding on Vensim's function.
What is the different between NPV, NPVE, and Net Present Value?

Re: How to map one variable to another variable?
I tried using VECTOR ELM MAP as suggested, but it seems it didn't work (or maybe i used it wrong?)Administrator wrote: ↑Fri Oct 09, 2020 3:57 pm Maybe vector elm map function is what you need?
You can use vector elm map to pick elements out from another subscripted parameter.

You would need to combine the subscript ranges into a single one. See the attached model.
Thank you so so much! Finally i got the answer on how to do that.
I owe you big time, Admin!<3

Hello mates,
I have one question.
How can i change the layout of my model from text to sketch view?
Tried to do it through the VIEW tab, but still couldn't get it into sketch view.
