Abstract
When the ship is attacked in the war, the wartime damage of fire fighting system will badly weaken the damage control capability and the survivability of warship. It is difficult for shipman to judge the damage state and make the damage control decision swiftly because of time and information constraints. So the design of a rapid and exact decision arithmetic for the wartime damage control of the damaged fighting system is very important. A new sort of method for modeling of damaged fire fighting system are brought forward firstly. Then based on intelligent decision arithmetic, the wartime damage simulation and intelligent decision system is founded. This intelligent decision system can improve effectively the decision-making and emergency repair capability of shipman in the wartime.
