Abstract
This validation processing device is provided with: a processing unit that performs model checking on a model to be checked; and a selection unit that selects, on the basis of the result of the model checking, one element from among elements that have undergone state change in a process leading to an unsafe event. The processing unit further performs model checking again on the model to be checked excluding the one element.
