MODEL CHECKING DEVICE FOR DISTRIBUTED ENVIRONMENT MODEL, MODEL CHECKING METHOD FOR DISTRIBUTED ENVIRONMENT MODEL, AND MEDIUM

摘要

A model checking device for a distributed-environment-model according to the present invention, includes: a distributed-environment-model search unit that adopts a first state as start point when obtaining information indicating a distributed-environment-model, searches the state attained by the distributed-environment-model by executing straight line movements for moving from the first state to a second state which is an end position, and determines whether the searched state satisfies a predetermined property; a searched state management unit that stores the searched state in the past; a searched-transition-history management unit that stores an order of the transitions of the straight line movements in the past; a searched state transition association information management unit that stores the transition when moving to another state in the past search in such a manner that the transition is associated with each of the searched states.
