Demand Forecasting & Inventory Optimization

A Machine Learning-powered inventory optimization system that forecasts product demand, calculates safety stock levels, determines reorder points, and helps businesses reduce stockouts while improving inventory efficiency.


Project Overview

This project combines Demand Forecasting and Inventory Optimization techniques to support data-driven supply chain decisions.

Key Objectives

  • Forecast future product demand using historical sales data
  • Optimize inventory planning
  • Calculate Safety Stock
  • Determine Reorder Points
  • Analyze forecasting accuracy
  • Visualize insights through an interactive dashboard

Business Problem

Organizations frequently face:

  • Overstocking and excess inventory costs
  • Stockouts and lost sales opportunities
  • Inaccurate demand planning
  • Poor inventory turnover
  • Inefficient replenishment strategies

This solution helps businesses improve inventory management through predictive analytics and machine learning.
