摘　　要：为了解决属性间具有优先关系的区间模糊多属性决策问题,将优先集成算子推广到区间毕达哥拉斯模糊环境,定义了区间毕达哥拉斯模糊优先加权平均(IVPFPWA)算子,研究了该算子的基本性质,给出基于IVPFPWA算子的多属性决策方法,通过决策实例说明了该方法的有效性和可行性。In order to solve the problem of interval fuzzy multi-attribute decision-making with priority relationship among attributes,the priority integration operator is extended to interval Pythagorean fuzzy environment.This thesis defines the interval Pythagorean fuzzy priority weighted average(IVPFPWA)operator and studies its basic properties.A multi-attribute decision-making method based on IVPFPWA operator is presented,and the effectiveness and feasibility of the method are illustrated by an example.
