Forecasting Demand More Accurately?
ML Demand Forecasting: 90% Accuracy, 4-to-54 Week Planning Window, and 4 Operational Domains Optimized
Case Study Summary
Executive summary
Whizzbridge engineered a machine learning-based demand forecasting engine for a retail client whose national logistics network was running on reactive inventory planning and inefficient labor scheduling. Built with Python, PySpark, Databricks, Airflow, SARIMAX, FB Prophet, XGBoost, and R Shiny, the pipeline delivers over 90% prediction accuracy across a 4-to-54 week planning window. The client now optimizes 4 operational domains: labor, truck routing, warehouse utilization, and vendor management, proactively, backed by predictive data rather than guesswork.

Challenges
- Unoptimized Supply Chain Operations – The client faced inefficiencies in labor usage, truck waiting times, and truck load capacity due to a lack of accurate demand forecasting across distribution centers and retail stores.
- Inefficient Warehouse Space Utilization – Without predictive visibility, managing warehouse inventory and movement was reactive and inconsistent.
- Vendor Planning & Resource Gaps – Poor demand insight led to suboptimal contracts with third-party logistics providers and unclear projections for truck and equipment needs.
The client required a machine learning-driven solution to forecast demand accurately and improve operational decisions across their national logistics network.
WhizzBridge’s Solution
- End-to-End ML Forecasting Framework – Built a custom pipeline to forecast truck inflow/outflow using a combination of SARIMAX, FB Prophet, and XGBoost models.
- Robust Data Processing Pipeline – Developed scalable ETL using PySpark and Airflow to perform comprehensive EDA, data cleansing, and feature engineering.
- Model Experimentation & Selection – Tested multiple algorithms and selected models based on performance, achieving over 90% prediction accuracy.
- Forecast Range Flexibility – Enabled forecast windows ranging from 4 to 54 weeks, accounting for external variables such as holidays and seasonality.
- Visual Analytics Dashboards – Created interactive dashboards using R Shiny, giving stakeholders real-time visibility into trends and forecast projections.
- Scalable Cloud-Based Infrastructure – Hosted the solution on Databricks, allowing seamless model training, collaboration, and future scalabilit
Results We Achieved
- Over 90% prediction accuracy delivered across a 4-to-54 week planning window.
- 4 operational domains now optimized proactively: labor scheduling, truck routing, warehouse utilization, and vendor management.
- Cost reduction through labor optimization and improved workforce efficiency.
- Data-driven vendor contract renegotiation with third-party logistics providers using predictive data.
The client now benefits from a scalable, ML-powered supply chain forecasting engine that enhances planning, reduces costs, and supports long-term growth.
