System for determining inter-element influence, device for determining inter-element influence, method for determining inter-element influence, and recording medium

In this inter-element influence determination device (1) a reception unit (11) receives request information from a user terminal (7). A system information storage unit (12) stores system information containing attribute information indicating the attributes of each element in a system. A relationship information storage unit (13) stores relationship information indicating relationships in which direct interaction is provided between elements. On the basis of the attribute information and the relationship information an influence determination unit (14) virtually connects each element included in the system, thereby creating a system network model which models the system, and on the basis of the system network model, determines whether a second element is influenced when a change is made to a first element. A transmission unit (15) transmits to the user terminal (7) determination result information indicating the result of the determination by the influence determination unit (14).
