Weak interdependency-cascading disruptions through more than intermediary events, i.e., transportation is inter-
dependent upon water distribution only to the extent that water utility workers require transportation routes to reach
workplaces.
Medium interdependency-cascading disruptions through foreseeable but loosely coupled relationships, i.e., transporta-
tion is loosely coupled to communications for control and dispatch, but can still be operated in degraded mode without
communications and centralized routing
Strong interdependency-cascading disruptions have engineered basis such as power systems are dependent upon fuel
supplies or public health facilities dependent upon power to electronic systems
