Multi-Echelon Inventory

Optimizing inventory across supply chain tiers

What Is It?

Multi-Echelon Inventory Optimization synchronizes inventory decisions across all supply chain stages.

  • Raw materials - Supplier inventory levels
  • Work-in-progress - Manufacturing buffers
  • Finished goods - Distribution centers & warehouses
  • Network optimization - Right inventory at right place & time

Supply Chain Echelons

Each echelon requires coordinated inventory policies

The Bullwhip Effect

Small demand fluctuations at retail cause progressively larger fluctuations upstream.

Multi-echelon optimization mitigates this by:
  • Coordinating inventory policies across levels
  • Sharing demand information throughout the chain
  • Optimizing network parameters jointly
