Class BowTieSvgExporter

java.lang.Object
neqsim.process.safety.risk.bowtie.BowTieSvgExporter
All Implemented Interfaces:
Serializable
public class BowTieSvgExporter extends Object implements Serializable
Exports BowTie models to SVG format for visualization.

This class generates SVG (Scalable Vector Graphics) representations of bow-tie diagrams for use in reports, presentations, and web applications. The SVG output follows standard bow-tie visualization conventions with threats on the left, the hazard in the center, and consequences on the right.

SVG Structure

  • Left side: Threats with prevention barriers
  • Center: Hazard (top event)
  • Right side: Consequences with mitigation barriers

Usage Example

BowTieModel model = new BowTieModel("HAZARD-001", "Vessel Rupture");
// ... configure model ...

BowTieSvgExporter exporter = new BowTieSvgExporter(model);
String svg = exporter.export();
Files.writeString(Path.of("bowtie.svg"), svg);
