Definitions

European Project Definitions

CIPRNet project

The CIPRNet project [1] uses the following definition:

Infrastructures are geographically dependent if a local environmental event can create state changes in all of them. [2]

E.g. if telecommunication and electrical distribution lines use the same bridge, the destruction of the bridge (local environmental event) has effects on the state of both infrastructures.

DIESIS project

The DIESIS project [3] gives the following definition:

Infrastructures are geographically dependent if a local environmental event can create state changes in all of them. [2]



Discussion Topic

The dependency model described in [4] argues that geographical dependency does not exist but is a Common Cause Failure event.
