Network failure
Critical-network fault isolation and cascade containment
This solution identifies physically actuatable fault boundaries: which breakers, valves, bypasses, links, or network connections should be interrupted before a local failure becomes a cascade. The proprietary method is sheaf-based fault isolation and graph-cut computation, grounded in topology rather than sampled fault histories.
Proprietary method
FIBI, Sheaf Sweep-Cut, CSI edge health, holonomy sheaf spectra, and AC power boundary operators.
Technical basis
Fault Isolation Boundary Identification paper; Cascade Containment Benchmark; AC Power Geometry Summary; Gas and PDP Network Evidence; cyclic fiber-optic sheaf papers.
Where it applies
Power grids, chemical plants, gas networks, telecom backbones, optical networks, infrastructure insurers, and critical facilities.
The FIBI paper validates Sheaf Sweep-Cut across TEP chemical, GasLib-4197 gas, and IEEE 118-bus power networks, returning a physical isolation cut rather than only a variable ranking. The AC power summary anchors grid claims in Dirichlet-to-Neumann maps and IEEE 118-bus boundary-operator framing, while the gas/PDP evidence summary keeps gas and reservoir-flow claims tied to public GasLib and well-test derivative results. The cascade benchmark reports 79.1% PEGASE containment, and the cyclic sheaf papers report telecom/core-network spectral speedups above 1000x, with a maximum of 3128.847x and eigenvalue error no larger than 8.049 x 10^-14.
