| Abstract: | For all attribute weights and values were interval numbers,through the objective of minimizing the total deviation between the alternatives and ideal object,maximizing the total deviation between the alternatives and negative ideal object,and maximizing the entropy of weights of each coefficient,the optimal solution was the best index weight coefficients,which was solved by Lagrange multiple method.Based on four different distance measure between interval numbers,the evaluating model for optimization of targets was established by applying TOPSIS rule.Lastly,the example was illustrated to compare the ranking effects by different measure.The result proved the definition of HaiMing holds the best reliability. |
| Keywords: | threat evaluation interval numbers entropy Lagrange multiple method TOPSIS rules |
