Abstract:

Due to the increasing size and complexity of the networked C4ISR system, system structure has become the main factor of every kind of system characteristic, especially survivability. The definition of networked C4ISR system structure survivability is analyzed. On the basis of the definition, an information flow model of system structure is proposed. Then the survivability assessment method based on the model is put forward as well. It includes attacking models under incomplete information, the means of measuring the system ability to fulfill missions, and the algorithm of assessing system structure survivability. Finally, the method is proved effective by simulating and assessing survivability of different area joint air-defense system structures.
