Analyzing device, diagnosing device, analysis method, and computer-readable recording medium

An analysis method comprising:

• identifying a model representing time evolution of a structure using a non-Gaussian random process, based on response of the structure;
• generating a probability model representing a distribution of an input, based on data indicating fluctuation of the input to the structure;
• generating an input signal for the structure based on the probability model;
• and
• deriving random response of vibration occurring in the structure in response to the input signal, based on the model and the input signal.

A non-transitory computer-readable recording medium storing a program for causing a computer to execute:

• processing of identifying a model representing time evolution of a structure using a non-Gaussian random process, based on response of the structure;
• processing of generating a probability model representing a distribution of an input, based on data indicating fluctuation of the input to the structure;
• processing of generating an input signal for the structure based on the probability model;
• and
• processing of deriving random response of vibration occurring in the structure in response to the input signal, based on the model and the input signal.
