In this article, we combine some fundamental theories of the Pythagorean 2-tuple linguistic sets (P2TLSs) with EDAS method and design the Pythagorean 2-tuple linguistic number (P2TLN) EDAS (P2TLN-EDAS) method for multiple attribute group decision making (MAGDM) issue. Firstly, the basic concepts of P2TLSs are introduced. Next, two aggregation operators of P2TLN are defined, and then the calculation steps of EDAS method are listed briefly. Furthermore, P2TLN-EDAS method is given for MAGDM problems and computing steps are proposed in detail. Finally, a computational example related to construction safety assessment is used to expound the effectiveness of the designed method. Meanwhile, we also carried out some comparative analysis between P2TLN-EDAS method and P2TLWA/P2TLWG operators and another P2TLN-TODIM method. The results show that P2TLN-EDAS method derives the same best alternative as P2TLWA, P2TLWG operators and P2TLN-TODIM method.

一种基于 EDAS 的基于勾股定理 2 元组语言信息的多属性群决策的新方法

在本文中,我们将勾股二元组语言集 (P2TLS) 的一些基本理论与 EDAS 方法相结合,设计了用于多属性群决策 (MAGDM) 的勾股二元语言数 (P2TLN) EDAS (P2TLN-EDAS) 方法) 问题。首先介绍P2TLS的基本概念。接下来,定义了P2TLN的两个聚合算子,然后简要列出了EDAS方法的计算步骤。此外,针对MAGDM问题给出了P2TLN-EDAS方法,并详细提出了计算步骤。最后,通过一个与施工安全评估相关的计算实例来阐述所设计方法的有效性。同时,我们还对P2TLN-EDAS方法和P2TLWA/P2TLWG算子以及另一种P2TLN-TODIM方法进行了一些比较分析。
