摘要:

研究了在属性之间存在优先级的情况下的广义犹豫模糊信息集成问题。考虑到属性优先级以及属性元素的统一程度的双重影响,首先给出了犹豫模糊信息下的熵值求法,并在其基础上提出了优先级混合赋权方法。之后,在该优先级混合赋权方法的基础上提出了广义犹豫模糊优先级混合几何(GHFPHG)算子,并给出了该类算子的优良特性。最后,利用案例验证了本文所提方法的实用性和有效性。

Abstract:

In this paper, we investigate the generalized hesitant fuzzy information aggregation issues in which the attributes are on different priority levels. Considering the impact of both attributes’ priority levels and the dispersion degree of hesitant fuzzy elements, we first give the entropy based on hesitant fuzzy information, and propose a prioritized hybrid weighted method accordingly. Then, we put forward generalized hesitant fuzzy prioritized hybrid geometric (GHFPHG) operator based on the hybrid weighted method. Furthermore, we discuss some desirable properties of the proposed prioritized operator. Finally, the practicality and effectiveness of the proposed approach are verified by a practical example.
