Supply Chain Simulation

1. Business Context and Objectives

Supply chains have become increasingly complex with global networks, just-in-time manufacturing, and interconnected dependencies. Traditional planning cannot anticipate cascading failures or test strategic changes without real-world risk. AI-powered supply chain simulation creates digital twins that generate synthetic scenarios, enabling organizations to stress-test resilience, optimize network design, and validate strategies before implementation, reducing disruption costs by 40-60%.

2. Practical Example

Real-World Scenario: A pharmaceutical company testing the resilience of its vaccine supply chain before a major expansion.

How It Works:

  • The AI creates a complete digital twin of the supply chain: 47 suppliers, 8 manufacturing sites, 200+ distribution centers
  • Generates synthetic disruption scenarios: “Category 5 hurricane hits Puerto Rico facility,” “Cyberattack on logistics provider,” “Raw material shortage from India”
  • Simulates cascading effects: “If Puerto Rico facility down for 3 weeks → 40% capacity loss → inventory depleted in 12 days → 2.5M patients affected”
  • Tests mitigation strategies: “Pre-position 6 weeks inventory in Atlanta → reduces patient impact to 500K → cost increase of $4.2M”
  • Runs 10,000 Monte Carlo simulations combining multiple disruptions and demand variations

Practical Output: The system delivers strategic recommendations like “Optimal network design: Add secondary supplier in Europe (cost: $15M), maintain 4-week safety stock at 3 regional hubs (cost: $8M annually), reduces severe disruption risk from 35% to 8%, protects $450M revenue”

3. Key Capabilities
