In order to provide commanders with more ideal assault route options,a multi-attribute decision making method based on intuitive fuzzy GRA and TOPSIS is proposed.Firstly,an evaluation index system of the assault route that conforms to the actual operation is analyzed and constructed.Then,the intuitive fuzzy weighted average operator in the intuitive fuzzy set theory is used to assemble the decision expert evaluation matrix,and the attribute weights are calculated by using intuitive fuzzy cross entropy.Then,the GRA-TOPSIS model is used to rank the assault routes to be selected by merit.Finally,through example calculation and comparative analysis,the validity and reliability of the proposed method are verified,which provides a new method for the evaluation of assault routes.
