Asymmetrical Smooth
Posted: Thu Oct 12, 2017 4:59 pm
Hi Tom/Colleagues,
I am modelling a situation where changes in the backlog of unmet demand is affecting changes in prices. In this particular case, it seems that negative changes in demand backlog has proportionally stronger impact on prices than positive changes (possibly due to market 'panicking').
Therefore, I am thinking of introducing a 'perceived' changes in the backlog, where positive changes are perceived more slowly (or more weakly) than negative changes. I don't know if this is clear enough. But basically, is there such asymmetrical SMOOTH function built into Vensim? If not, do you have any thoughts on how to implement it (more neatly than just putting in an arbitrary fudge factor)?
Thank you in advance!
