Bit-array backed Binary Decision Diagram solver

Probabilistic Risk Analysis Tool (fault tree analysis, event tree analysis, etc.)

The Colorado University Decision Diagram (CUDD) package is written in C for the manipulation of decision diagrams. It supports binary decision diagrams (BDDs), algebraic decision diagrams (ADDs), and Zero-Suppressed BDDs (ZDDs).

Event Modeling Risk Assessment using Linked Diagrams (EMRALD)

XFTA is a powerful and efficient calculation engine for fault trees and related models.

OpenPRA model fixtures generated on the fly for testing and benchmarking solvers. Models stored in a persistent container for easy consumption.
