Abstract: The rational selection of emergency relief materials for earthquake disaster has a very important impact on reducing casualties and reducing the loss of property of the victims. To solve the earthquake emergency material transportation decision-making problem under unknown weights of attributes circumstance, an improved VIKOR method which combines with the Pythagorean fuzzy uncertain linguistic variables (PFULVs) and prospect theory, called PFUL-PT-VIKOR method, is proposed. Firstly, the Pythagorean fuzzy uncertain language is applied to describe and aggregate the expert's perception information of earthquake emergency materials transportation schemes considering the influence of multiple attributes. And then, the weights of attributes are calculated by the subjective and objective fusion method. After that, based on the prospect theory, an improved VIKOR method is introduced to ranking the emergency material transporting solutions. Finally, an illustrate example is given to verify the effectiveness and practicability of the proposed method. The results show that the proposed PFUL-PT-VIKOR model is helpful to enhance the knowledge representation ability of decision-makers on the information perception of uncertain emergency situations, solve the problem that attribute weighting is too subjective or too dependent on samples, and break through the mindset that the implicit psychological behavior of emergency decision-makers is difficult to quantitatively apply, which enhance the practical applicability of model and provide decision support for the reasonable transportation scheme of earthquake emergency materials.
