4 scénarios permettent de comparer le comportement selon le délai de réaction aux variations de la demande clients. Plus la réaction est rapide, plus les oscillations sont amples. Pour les atténuer, il faut au contraire réagir plus lentement. C'est un exemple de levier efficace à actionner dans un sens contre-intuitif.

This Insight is a simple model of a sluggish shower, the classic example from Systems Thinking of a balance loop with delay. It illustrates the sometimes baffling influence that time delays can have on simple decision making tasks.

 Just playing around with delay functions.      Does not model the hog supply chain in any way shape or form.

It is a simple model to show how different parameters like inventory adjustment time and delay in ordering affect the inventory replenishment system. User can change values of all the parameters.

 This model of a single simple shower is based on a 1994  paper  by John Morecroft et al of the London Business School.  It is used to show the impact of delay on control of a simple system.
