A Multi-stage Conflict Style Large Group Decision-making Emergency Method Based on Interval Fuzzy Number
For the multi-period large group emergency decision-making problem that stage weights are unknown and preference information is interval fuzzy number(IFNs), a new group decision-making method is proposed. Firstly,the similarity formula between INs is given, and each stage preference information is clustered by this for-mula.Then,the trelative entropy method is used to determine cluster weights and stage weights.The alternatives ranking result is obtained based on the comprehensive group preference, and the best alterative is selected.Fi-nally, an example shows the effectiveness and practicability of this method.
