ALBERT DELOIN, specialist in the DDMRP method, has implemented this management and planning method in its software offer.

The DDMRP method (developed by Carol Ptak and Chad Smith, co-directors of the Demand Driven Institute) is fully integrated into our offer. Most of the basic mechanisms of the DDMRP method were already present in the PFP6 method and in the AD6 software range.

DDMRP is a method for planning and executing supply, manufacturing and distribution scenarios. It consists of implementing buffers at strategic locations in the supply chain, whose objective is to decorrelate the need (demand) from production (or supply): this is consumption
(*) The buffers are an expression of the daily consumption (ADC), lead time, launch batch and the risk of variation (security).
It is important to note that the DDMRP method is a pull flow management method:

  • The 3 DDMRP buffers are an equivalent of the pull flow setting in the Kanban method,
  • The trigger rule (available flow equation) is comparable to the Kanban rule, except that it incorporates demand peaks (non-standard needs).

Positioning of buffers
Strategic decouplin

Chaque buffer DDMRP est structuré autour de 3 zones distinctes, qui servent à déterminer les niveaux d’alerte et guider les décisions : • Zone verte : Cycle de réapprovisionnement – indique la quantité à produire ou à approvisionner régulièrement ; • Zone jaune : Délai pour programmer, produire et livrer le consommateur – assure l’autonomie durant le lead time ; • Zone rouge : sécurité – absorbe les variations imprévues de la demande ou de l’offre.

Planning
Demand-driven planning

Le DDMRP repose sur l’ équation de flux disponible, qui croise les besoins « qualifiés » (retards + livraison du jour + pics de commande), les ressources disponibles et les niveaux de buffers. Contrairement au MRP, qui déclenche des actions sur la base de prévisions souvent obsolètes, le DDMRP réagit aux consommations réelles, actualisées en continu.
