Abstract
A monitoring device includes: an operation record acquisition unit configured to acquire operation records indicating a transition in a load factor or a load change factor with respect to operation time leading up to failure in failure cases; a threshold setting unit configured to set a threshold to be contrasted with the load factor or the load change factor in the operation records of the failure cases; a wear rate acquisition unit configured to acquire a wear rate that is a value derived from a relation between the load factor or the load change factor and the threshold and indicates a degree of progress of wear of a device according to operation time; and a failure rate cumulative frequency acquisition unit configured to acquire a transition in a failure rate cumulative frequency of the failure cases with respect to the wear rate.
