PROBLEM TO BE SOLVED: To frequently maintain an entire system when the failure risk of each subsystem is unknown, and maintenance cost is incurred. SOLUTION: A failure risk evaluation system 10 acquires a failure history of an entire system composed of a plurality of subsystems and a maintenance history of at least one subsystem selected from the plurality of subsystems. And, based on the failure history of the entire system and the maintenance history of at least one subsystem, a failure risk evaluation model for evaluating the failure risk of other subsystems without maintenance history is calculated, and the failure of other subsystems A failure risk evaluation model calculation unit 12 for obtaining a risk is provided.
