Interdependency
Contents
Definitions
Official European Definition
One of the most cited definitions of interdependency is the one by Rinaldi et al. who define interedependency as a bidirectional relationship between two infrastructures through which the state of each infrastructure influences or is correlated to the state of the other [1]. This definition is adopted on the Commission's staff working document on a new approach to the EPCIP [2].
National Definitions
USA
Mutually reliant relationship between entities (objects, individuals, or groups) [3]. The degree of interdependency does not need to be equal in both directions. For example, the Energy Sector depends on a functioning Water Sector for successful day-to-day operations, just as the Water Sector needs energy to effectively manage water and wastewater systems [4].
Germany
Interdependency is the complete or partial mutual dependency of several goods or services [5].
