The Importance of Demand Forecasting
Accurate demand forecasting is the foundation for inventory optimization, production planning, and logistics efficiency. Excess inventory increases costs, while stockouts result in lost sales.
Time Series Analysis Techniques
ARIMA
A traditional statistical method that decomposes trends and seasonality for forecasting. Stable but weak against nonlinear patterns.
Prophet
A time series forecasting tool developed by Facebook that automatically decomposes trends, seasonality, and holiday effects. Easy to use even for non-experts.
LSTM
A deep learning-based sequence model that learns long-term dependencies. Strong with complex patterns but requires large amounts of training data.
Transformer-Based
The latest time series Transformer models demonstrate outstanding performance in multi-step forecasting.
Ensemble Approach
Combining predictions from multiple models improves accuracy by 10-15% compared to single models.
Application Case
