摘　　要：针对毕达哥拉斯环境下的多属性群决策问题,首先,将毕达哥拉斯模糊数和幂均算子相结合,创造性地拓展了一种新的改进加权支持度;然后,基于此提出了改进加权支持度的毕达哥拉斯模糊交叉幂均算子,并讨论了该算子的性质,进而建立一种毕达哥拉斯模糊背景下能够反映决策属性间相互作用的决策方法;最后,将其应用于智慧城市的评价中。实例分析表明,该方法可以解决实际的多属性群决策问题,并可以进一步应用到智慧物流、模式识别、人工智能等领域。For the multi-attribute group decision-making problem in Pythagoras environment,firstly,this paper combined the Pythagorean fuzzy number and the power-average operator to creatively expand a new improved weighted support,then based on this,it proposed a Pythagorean fuzzy interaction power-average operator with improved weighted support,and discussed the properties of the operator.Then it established a decision-making method that could reflect the interaction between decision attributes under Pythagoras fuzzy background.Finally,it was applied to the evaluation of smart cities.The case study shows that the method can solve the problem of actual multi-attribute group decision-making and can be further applied to the fields of intelligent logistics,pattern recognition and artificial intelligence.
