Technical description of the ASF pen-level simulation web tool, development stack, exports, and deployment.

ASF Simulation Web Tool

The ASF pen-level simulation is an interactive, browser-based decision-support dashboard. Users enter pen-wise population, infection, and control parameters. The application computes disease trajectories and key indicators and visualizes outputs as epidemic curves.

Development Environment & Tools

• Visual Studio Code — PHP/HTML/CSS/JS development
• XAMPP (Apache + PHP) — local testing
• Browser Developer Tools — debugging and profiling

Languages & Frameworks

• PHP — page routing and layout
• JavaScript — simulation engine and indicators
• Tailwind CSS — responsive UI
• Chart.js — epidemic curve visualization

How It Works in the Browser

Inputs → validation → simulation loop → array generation → Chart.js rendering → client-side downloads (CSV / PNG / HTML).

Deployment

• Upload genasf_simulation.php and assets to web directory
• Ensure CDN dependencies load correctly
• Test exports across browsers
