A method of information quality assessment of ship ASW operation

As it is difficult to assess quality of information of ship anti submarine warfare (ASW) operation by traditional methods, this paper gives a new method to solve the problem and builds a model of information quality assessment based on information entropy. Further, ASW ship operation information quality assessment database is given to offer a way to acquire the quality of information (QoI) in time indexed by the operation situation and operation time in the database. The method gives a beneficial way to evaluate the ship ASW operation efficiency and offers an aid for ship operation decision.
