Welcome to SEIR Model Scenario Simulation System
This system provides three different epidemic modeling and analysis tools to help you quickly calculate transmission capacity, assess trends, and evaluate intervention effectiveness
Calibration Tool: R0 Calculator
Fit actual cumulative case numbers by manually adjusting parameters to assess model accuracy
- Real-time parameter adjustment and visualization
- Import real data for comparison
- Parameter perturbation confidence band analysis
- Fit metric evaluation (R², RMSE, MAE)
- Support for cumulative cases and death data
Prediction Tool: β Piecewise Prediction
Simulate R0 values for different time periods to predict epidemic development trends
- Customize transmission rate coefficient β by time period
- Display R₀ value changes across phases
- Drag chart to adjust phase boundaries
- Daily new cases and death predictions
- Confidence interval uncertainty analysis
Simulation Tool: Intervention Configuration
Evaluate the effectiveness of single and combined interventions to optimize control strategies
- Non-pharmaceutical interventions
- Pharmaceutical interventions
- Intervention timing and intensity optimization
- Scenario comparison and decision support
- One-click save prediction results
