INFORMATION PROCESSING DEVICE AND ERROR DETECTION METHOD

摘要

The present invention provides an information processing device that improves the detectability of system errors. This information processing device comprises: a means that generates a state graph on the basis of relationship change information indicating change in the relationship between a plurality of elements included in a system, said state graph having the elements as the vertices thereof and the relationship between the elements as the sides thereof; a means that generates a normal model having the state graph as a set of conditions to be fulfilled during normal system operation, on the basis of the relationship change information; and a means that detects system errors and outputs error information indicating detected errors, on the basis of the state graph and the normal model.
