Network Equipment Fault Maintenance Decision System Based on Bayesian Decision Algorithm

Bayesian network is a directional loop topology composed of graph theory and probability principle. The input data can be classified by expressing the causal relationship between variables in the way of directed connection and expressing the correlation degree between variables in the way of probability. It avoids complicated operation and improves the efficiency of fault diagnosis. The performance of network devices deteriorates gradually. After a certain period of time, an alarm is generated indicating that the performance deteriorates. If the network devices are not repaired in time, the network devices will be faulty soon. Based on Bayesian decision algorithm, the hierarchical structure of network equipment fault maintenance decision system is designed, and the criteria of Bayesian decision algorithm and the decision model of network equipment fault maintenance are constructed. The research results can make decision on network equipment fault maintenance and improve the level of network equipment fault diagnosis and maintenance.
