Abstract: Aims at the uncertainty of the Command and Control Group Decision-Making, the paper explores the method based on intuitionistic fuzzy set to solve the optimizing scheme in the Command and Control Group Decision-Making. Firstly, according to the specific mission task, the decision expert gives the attributive weight and the value decision-making scheme. Secondly, calculate the di®erence between the weight of the attributes and the weight of the attributes given by decision experts, then choose the appropriate decision experts based on the di®erence values and determine their weights. Thirdly, the comprehensive weight of each attribute is modified and the decision alternatives are sorted. At last, the validity and rationality of proposed method are tested by numerical examples.
