Title:
METHOD FOR MANAGING FAILURE OF FACILITY
Document Type and Number:
WIPO Patent Application WO/2010/061681
Kind Code:
A1
Abstract:
Provided is a method for managing the failure of a facility which has the sufficient-accuracy results of reasoning, can estimate an optimal repair time for a failure or other failures which possibly occur simultaneously with or subsequently to some failure, and can be adopted in large equipment used in a plant. The method for managing the failure of a facility is designed in such a manner that a monitoring means monitors the operational state of a facility, and an estimating means estimates the cause of the failure of the facility by using as a node the measurement data about the operational state of a facility obtained by the monitoring means when the failure occurs in the facility, wherein acoustic data closest to a sound produced from the facility in which the failure occurred is selected from a plurality of elements of acoustic data provided previously, form data closest to the form of the facility in which the failure occurred is selected from a plurality of elements of form data provided previously, the acoustic data and form data thus selected are added to the node, and then the cause of the failure of the facility is estimated by a first Bayesian network based on the node.
