EVENT ANALYSIS/COUNTERMEASURE SYSTEM USING BAYESIAN NETWORK

摘要

There is provided an event analysis/countermeasure system using a Bayesian network. When an event has occurred, the cause of generation of the event is estimated by using the Bayesian network and an optimal countermeasure method is outputted. The event analysis/countermeasure system using the Bayesian network includes: a probability table; an event information input unit for receiving event information; a countermeasure plan creation unit for creating a combination of countermeasures for the event; a Bayesian network calculation unit for outputting cause probability distribution data; an evaluation function processing unit for calculating an evaluation value for the countermeasure according to a predetermined evaluation function; and a countermeasure plan evaluation unit for outputting countermeasure plan data having a high efficiency as a countermeasure plan list according to the evaluation value for the countermeasure calculated.
