AI-Driven Inventory Optimization

12 months28 professionals$5.8M budgetCompleted October 2024

Executive Summary

A global retail chain with 2,000+ stores faced significant challenges with inventory management, experiencing frequent stockouts and excessive inventory costs. We implemented an ML-powered demand forecasting and inventory optimization system that reduced stockouts by 67% while cutting inventory costs by 23%, generating $18M in additional revenue annually.

The Challenge

Inefficient inventory management across 2,000+ stores leading to lost sales and excess costs

Key Issues

  • Stockout rates averaging 12% during peak periods
  • Excess inventory tying up $45M in working capital
  • Manual forecasting processes taking 2 weeks per cycle
  • No real-time visibility into cross-store inventory
  • Seasonal demand patterns poorly understood

Business Impact: $30M annual revenue loss from stockouts and markdown costs

The Solution

ML-powered demand forecasting with real-time inventory optimization across all locations

Phase 1: Data Foundation

Duration: 2 months

  • Integrated POS, inventory, and supply chain systems
  • Built unified data lake on Azure
  • Established real-time data pipelines
  • Created data quality monitoring framework

Phase 2: ML Model Development

Duration: 4 months

  • Developed demand forecasting models using TensorFlow
  • Created inventory optimization algorithms
  • Built recommendation engine for transfers
  • Implemented A/B testing framework

Phase 3: Rollout

Duration: 4 months

  • Pilot deployment to 100 stores
  • Iterative model refinement based on results
  • Full rollout to all 2,000+ locations
  • Training for 500+ store managers

Phase 4: Optimization

Duration: 2 months

  • Performance tuning and model updates
  • Integration with supplier systems
  • Automated reorder point calculations
  • Mobile app deployment for managers
