PURPOSE: A failure level determination method of an operation system for securing the stability of an operation system is provided to accurately determine a failure level by considering a method for determining a failure grade. CONSTITUTION: It confirms whether there is a failure event through event information(S101~S107). A failure event elements is subdivided(S109). An environmental variables by a field suitable for an element is set up(S111). A type of the fault event defines(S113). The environment variable is applied to the type definition(S115). The final fault level is determined(S117).
