SimDec - Simulation Decomposition
เข้าร่วมเมื่อ 4 มิ.ย. 2021
SimDec is a new generation sensitivity analysis technique that delivers actionable insight.
By decomposing your decision-making indicator by the influence of input factors, SimDec reveals causalities, interactions, and provides actionable information. The more complex your model is, the more insights you will get with SimDec.

It’s not so clear if you use the same range of parameters variation for Tornado diagram and SIMDEC? It’s very important to compare the same scenarios because the results are different! It’s very impressive!
Thank you! Excellent question. Indeed, it is important to compare fairly, and we do! The same ranges of input variables as in Tornado are taken for SimDec. So the two graphs you see in the video, Tornado and SimDec, are built on identical initial information.
