Re: SD models for demand forcasting
I am looking for "generic structures" for demand forecasting in system dynamics. below is an article for a generic case of a supply chain (no product is mentioned in the article). a simple smoothing structure is used in this case. https://www.researchgate.net/publication/220636353_Demand_f...

SD models for demand forcasting
Hi,
I am looking for SD models for demand forecasting in the context of product consumers and supply chain. Can anyone share models or guidelines for modeling demand in general in SD?

Re: requesting resources to understand the mathematics behind system dynamics models
hi- thanks for the explnations. i think my question is probabaly not well undestood. I am not asking what are the necessary mathematics to develop system dynamics models. perhaps a basic knowledge of algebra would probably be enough to develop or at least understand the basic models. what I am looki...

Re: requesting resources to understand the mathematics behind system dynamics models
I am asking this in the context of the managing supply chains and inventory. I am looking for simple examples that shows how the matematics of system dynamics works. when runing a simple model, say population with one stock only, it looks very intuitive to see the behavior. however, the matematic an...

requesting resources to understand the mathematics behind system dynamics models
Hi,
I am trying to understand the mathematics behind system dynamics models.
could you please suggest some resources to read (maybe with very simple examples)?
attached to this post is a file that I have found, however it is complicated for those with non-engineering background.
thanks.

Road Maps models
Hello everybody,
has anyone built "creative learning exchange- Road Maps" models? appreciate if you could share the models here.

Understanding Delays
Hi everyone, can anyone explain the logic behind the outflow equation in a first order material delay? why the equation is set to the: Outflow = Material in Transit/Average Delay Time why this division is an estimation of outflow in a material delay? is this the same with the decision rule for outfl...
