  3. Simulation, Forecasting & AI Integration

    6 weeks
    Goals
    • Build discrete-event simulations of warehouse picking operations using SimPy or AnyLogic
    • Develop SKU-level demand forecasting models using Prophet and LightGBM

Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

SKU Velocity Analyzer & ABC Classifier

Beginner

Build a Python application that ingests warehouse pick-log CSV data, computes SKU velocity metrics (picks/day, units/day, order frequency), performs ABC/XYZ classification, and visualizes the results in an interactive dashboard. This project teaches foundational data analysis skills essential to all slotting work.

MIP-Based Slotting Optimizer for a Small Warehouse

Intermediate

Formulate and solve a mixed-integer programming model using Google OR-Tools or PuLP that assigns 500 SKUs to 800 locations in a simulated warehouse. Minimize total weighted travel distance subject to capacity, zone, and compatibility constraints. Compare solver results against a naive random assignment and a manual heuristic.

Warehouse Pick-Path Simulation with SimPy

Intermediate

Build a discrete-event simulation of a zone-picking warehouse using SimPy. Model picker movement, aisle congestion, and order batching. Run the simulation under two different slotting layouts and compare average order cycle time, picker utilization, and bottleneck locations.

AI-Powered Demand Forecasting for Slotting Decisions

Intermediate

Develop a demand forecasting pipeline using Prophet and LightGBM on historical order data to predict SKU-level demand for the next 4 weeks. Feed the forecasts into a slotting optimizer that dynamically adjusts product locations based on predicted velocity changes. Evaluate forecast accuracy and its impact on slotting quality.

RL-Based Dynamic Slotting Agent

Advanced

Implement a reinforcement learning agent (using Stable Baselines3 PPO) that learns to dynamically reassign SKU locations in a simulated warehouse environment. The agent observes current inventory levels, pending orders, and congestion patterns, then decides whether and where to re-slot products. Train the agent over thousands of episodes and benchmark against static slotting and MIP-based approaches.

LLM-Powered Slotting Analyst Chatbot

Advanced

Build a LangChain-powered conversational agent that connects to your slotting optimization database and warehouse analytics. Users can ask natural-language questions like 'Which SKUs should I re-slot before the holiday season?' or 'Why did pick rates drop in Zone C?' and receive data-backed answers with visualizations. Integrate with OpenAI function calling for structured queries.

Build a production-grade slotting optimization pipeline: automated data ingestion from a Snowflake warehouse, velocity computation, demand forecasting, MIP optimization, result validation, and WMS API integration. Deploy using Docker + AWS Lambda, with GitHub Actions CI/CD running backtests on every commit. Include monitoring dashboards in Power BI.
