Abstract: To solve the problem of emergency logistics decision-making,a linguistic interval-valued intuitionistic fuzzy group decision-making method was proposed,which had taken into account the demands of plan implementers and the qualitative representation of plan preferences.To overcome the aggregation failure phenomenon of existing operators and effectively aggregate linguistic interval-valued intuitionistic fuzzy numbers,the Lukasiewicz operation laws and aggregation operator were developed.Aiming at the maximizing group consensus,an expert weight optimization model was constructed based on distance measure to obtain a reliable comprehensive evaluation matrix.A linguistic interval-valued intuitionistic fuzzy Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) was proposed based on lexicographic order relation to obtain positive and negative ideal values of each attribute.A group decision-making method for emergency logistics plans was constructed,and some examples were given to verify the rationality and scientificity of the proposed method.

Key words: linguistic interval-valued intuitionistic fuzzy sets, weight averaging operator, emergency logistics plan, group decision-making
