forio.com - User Input

Thomas Sarno... 27 posts

I'm building out a sim where a user needs to input 3 price inputs per week for 4 weeks (I'm considering this one step within the simulation). The simulation takes these 12 prices and computes profitability, etc. Right now I have 12 input fields, each referenced by it's own forio variable. Is there a) an easier way to input these 12 price fields and b) can I utilize an array so I don't have to keep track of 12 prices and perform operations on all to get a 4 week summary result? Any examples you can point me to?

Thanks,
Tom

Hi Thomas,

A Forio array is perfect for this. Define a range

R pricesegment = 1..12

Then define decisions and variables that will be automatically repeated over that range

D Price Input[pricesegment] = 100
V Sales[pricesegment] = 1000
V Revenue[pricesegment] = Price * Sales

All of the above have 12 different values. For more info, see

Hey,

I have built for you a good example sim which you can copy from.

This model uses an array, and then 2 range controllers (1 for each range) and a decision input to set all 12 decisions

Hey,

Let me know how it goes, or if you need anything else.
