Accurate demand forecasting is the cornerstone of an efficient supply chain, allowing organizations to optimize inventory, reduce stockouts, and enhance customer satisfaction.
Oracle Cloud Demand Management leverages advanced machine-learning algorithms to predict future demand based on historical data, employing multiple forecasting methods to generate a statistically reliable forecast. The system further refines predictions using a Bayesian approach to blend results from different methods and configurable forecasting parameters to fine-tune the outputs.
One of the key objectives in demand forecasting is achieving the best-fit forecast, which involves fine-tuning forecasting methods, causal factors, and parameter settings to enhance accuracy.
The Evolution of Forecast Tuning
Forecast tuning plays a crucial role in ensuring demand predictions align closely with actual market behaviour. The traditional approach can be described as below:
- Manually adjusting forecasting parameters through trial and error.
- Selecting appropriate forecasting methods (e.g., ARIMA, Exponential Smoothing, Machine Learning models).
- Configuring seasonality settings (e.g., monthly, quarterly, annual trends).
- Testing different lookback periods (e.g., using 6 months, 12 months, or 24 months of historical data).
- Evaluating forecast accuracy using metrics like MAPE, RMSE, and bias.
While effective, this manual approach can be labour-intensive, time-consuming, and possibly inconsistent across forecasting nodes.
A Simple Analogy: Baking a Cake
Imagine you are baking a cake, and you need to decide:
- The oven temperature (e.g., 160°C, 180°C, 200°C)
- The baking time (e.g., 25 min, 30 min, 35 min)
- The amount of sugar (e.g., 100g, 150g, 200g)
Any combination could result into a cake being baked, but to get the best one you might bake multiple cakes, adjusting the temperature and time to get the best texture and taste. If you manually test all combinations, it would take a long time. This trial-and-error method is similar to traditional forecast tuning.
Introducing Automated Hyperparameter Tuning
Automated hyperparameter tuning eliminates this trial-and-error process by leveraging machine learning to optimize parameter selection. Instead of manually testing various combinations, the system:
- Runs multiple models with different parameter values.
- Evaluates performance using accuracy metrics like MAPE.
- Adjusts parameters intelligently to find the best combination.
Similar to how a smart baking assistant would test and adjust baking conditions for the perfect cake, automated tuning refines forecast parameters for optimal accuracy.
