[System Design] Part 4 — Amazon CONDOR & Anticipatory Shipping

Short summary

Amazon's fulfillment network uses three-tier optimization: Anticipatory Shipping (ML predicts demand weeks ahead, pre-positions inventory to local hubs), Regionalization (8 US autonomous regions reduced travel distance 60%), and CONDOR (continuous re-routing within a 5-6 hour pre-fulfillment window). CONDOR solves Prize Collecting Vehicle Routing Problem to maximize on-time delivery while minimizing transport cost.

• •Anticipatory Shipping: ML predicts regional demand 3+ days ahead, moves inventory before orders placed
• •Regionalization: 8 autonomous US regions cut avg travel distance per package by 60%
• •CONDOR: Continuous optimization engine re-evaluates routing every 15 minutes during 5-6 hour fulfillment window
