pyrbd3 0.1.2

Fast Reliability Block Diagram Evaluation Tool

PyRBD3

Fast and lightweight Reliability Block Diagram (RBD) evaluation library, powered by modern C++ and pybind11. Provides high-performance algorithms for minimal cut sets, path sets, and system availability computation.

Installation

Precompiled binary wheels are available for Linux:

pip install pyrbd3

That’s it — no compiler setup or manual build steps are required. If you prefer a clean environment:

conda create -n pyrbd3 python=3.10
conda activate pyrbd3
pip install pyrbd3

Quick Example

from pyrbd3 import read_graph, evaluate_availability

topo = "Germany_17"
G, _, _ = read_graph(f"topologies/{topo}", topo)

node_prob = {node: 0.9 for node in G.nodes()}

src, dst = 0, 1

availability = evaluate_availability(G, node_prob, src=src, dst=dst, algorithm="sdp")

print(f"System availability from {src} to {dst} in {topo}: {availability:.6f}")
