The purpose of the present invention is to provide a system analysis device capable of performing appropriate analysis of a system in which input/output relations are dynamically determined. The present invention, intended for a system in which an internal state changes due to an input, and an output for the input changes in response to the change of the internal state, is provided with: a state transition model construction means for constructing, on the basis of state transition rules of the system, a state transition model including a plurality of state values that the system can adopt and a transition path between each of the state values; an initial state value setting means for setting an initial state value that satisfies a prescribed start-time condition from among the plurality of state values; an end state value setting means for setting an end state value that satisfies a prescribed end-time condition from among the plurality of state values; and a state transition path presence determination means for determining whether a state transition path for reaching the initial state value from the end state value is present in the state transition model.
