I wanted to ask about the solution of parametric models.
Is it possible to solve parametric model (like Austria PVC model solved using Gabi, Excel, and Umberto given in Practical handbook for MFA) using STAN?
You can define linear relationships of flows. that might be the closed to what I understand when i hear parametric model?
But you may elaborate your question, a bit. What specifically do you want to do.
if you go to Edit > Edit relation... you can define linear relationships of the processes.
I just tried that for the year 1960, as you can see in the screenshot below.
I just defined 2 relationships and set the values for recycling and sales in 1960.
However, as Stan is not able to work with non-linear fuctions you need to calculate the sales rate (hird-order polyno-mial function) outside STAN (in Exccel for instance and copy the values into STAN [FAQ as a section on how to import values from excel)
