Selection of Main Attack Direction of Attack Plane Formation with TOPSIS

In accordance with the characteristic of main attack direction of attack plane formation,the selection of main attack direction is studied by the basic principle of technique for order preference by similarity to ideal solution.The mathematical model of multiple attribute decision making is found under indefinite information.The power coefficient of each factor would be defined by adopting the entropy power law.The concept of the distance degree and its calculation method are given.Each scheme would be carried on the good and bad sequencing according to the synthesis quota value.Finally,it indicates that the method is effective and feasible by an example.
