This simulation allows you to compare different approaches to influence flow, the Flow Times and the throughput of a work process.
By adjusting the sliders below you can
observe the work process without any work in process limitations (WIP Limits),
with process step specific WIP Limits* (work state WIP limits),
or you may want to see the impact of the Tameflow approach with Kanban Token and Replenishment Token
or see the impact of the Drum-Buffer-Rope** method.
* Well know in (agile) Kanban
** Known in the physical world of factory production
The "Tameflow approach" using Kanban Token and Replenishment Token as well as the Drum-Buffer-Rope method take oth the Constraint (the weakest link of the work process) into consideration when pulling in new work items into the delivery "system".
You can also simulate the effects of PUSH instead of PULL.
Feel free to play around and recognize the different effects of work scheduling methods.

The work flow itself
Look at the simulation as if you would look on a kanban board.
The simulation mimics a "typical" software delivery process.
From left to right you find the following ten process steps.

Bienvenue sur le simulateur du modèle à flux constants.
Ce modèle est basé sur notre cas d'étude simplifié : un groupe de guépards dans un parc national géré, où les entrées et sorties sont contrôlés par les gestionnaires (translocation entre parcs).
Fonctionnement :
Le [Variable d'état] qui représente l'effectif de guépards (le nombre d'individus).
Les [Flux] (B, I, D, E) sont le nombre fixe d'individus qui entrent ou sortent à chaque pas de temps.
Variables forçantes : Les décisions des gestionnaires sont les "variables forçantes" qui rendent ces flux constants.
Votre mission :
Utilisez les curseurs pour régler les conditions et lancez la simulation en cliquant sur le bouton "SIMULATE" en haut à droite, pour observer comment l'effectif évolue sur le graphique !
