ELECTRIC POWER INFORMATION SYSTEM HEALTH ASSESSMENT METHOD AND SYSTEM BASED ON FUZZY INFERENCE THEORY

摘要

An electric power information system health assessment method and system based on fuzzy inference. The method comprises: acquiring, according to assessment requirements, log data generated during operation of an electric power information system, and preprocessing the log data to obtain log information in a uniform format (S100); performing log information screening and log fusion by using a fuzzy inference theory to obtain integrated log information (S200); analyzing the integrated log information to obtain log events and association information between the log events (S300); mining the association between the log events on the basis of log data mining technology and log event summary analysis technology (S400); and constructing an electric power information system health assessment model on the basis of the mining result, and assessing indicators of the electric power information system according to system health assessment indicator values comprised in the electric power information system health assessment model (S500).
