FAILURE INFLUENCE ANALYSIS DEVICE, APPLICATION SYSTEM, AND FAILURE INFLUENCE ANALYSIS METHOD

摘要

PPROBLEM TO BE SOLVED: To properly specify the range of the influence of a failure, in a failure influence analysis device for analyzing the influence of a failure which has occurred in components in a system configured of a plurality of components. PSOLUTION: A failure detection part 121 detects whether any of components configuring a system fails or not. A cause range extraction part 122 extracts other components on which the operation of the components determined to be faulty by the failure detection part 121 depends, and defines them as cause range components. A failure investigation part 123 investigates whether any of the cause range components extracted by the cause range extraction part 122 fails or not. An influence range extraction part 131 extracts the other components whose operation depends on the components determined to be faulty by the failure detection part 121 or the failure investigation part 123, and defines them as influence range components.
