NETWORK MANAGEMENT BASED ON MODELING OF CASCADING EFFECT OF FAILURE

摘要

A system and method of managing a network with assets are described. The method includes generating a directed graph with each of the assets represented as a node, determining individual failure probability of each node, computing downstream failure probability of each node according to an arrangement of the nodes in the directed graph, computing upstream failure probability of each node according to the arrangement of the nodes in directed graph, and computing network failure probability for each node based on the corresponding individual failure probability, the downstream failure probability, and the upstream failure probability. Managing the network is based on the network failure probability of the assets.

1. A network management system to manage assets of the network, the management system comprising:
a memory device configured to store instructions; and a processor configured to process the instructions to compute network failure probability associated with each asset based on determining individual failure probability, upstream failure probability, and downstream failure probability for each asset, and to manage the network based on the network failure probabilities of the assets.
