Dear, this is the LearingYard Academy!
Today, the editor brings the "intensive reading replica paper 'A linguistic Multi-Attribute Decision-Making approach based on the CWPHM operator and C-DEMATEL' for code reproduction (20)".
Welcome to visit!
一、内容摘要（Content Summary）
本期推文将從思維導圖、精讀内容、知識補充三個方面介紹精讀複刻論文《基于CWPHM算子和C-DEMATEL的語言型多屬性決策方法》的代碼複刻（20）。
In this issue, we will introduce the code replication (20) of the refined reading paper "Language Type Multi-Attribute Decision-Making Method Based on CWPHM Operator and C-DEMATEL" from three aspects: mind map, refined reading content, and supplementary knowledge.
二、思維導圖（Mind Mapping）
三、精讀内容（Detailed Reading Content）
對比方法3将利用雲權重幂平均（CWPA）算子對各備選幹部的多種屬性值進行集結，以此得到基于CWPA算子的綜合評價結果。根據參考文獻[26]，CWPA算子的定義如下圖所示。并且，CWPA算子的綜合評價值以雲的總計分值給出，其可以依據雲的總計分值大小進行排序，即該算子的排序結果由雲總計分進行。
Method 3, in contrast, will utilize the Cloud Weighted Power Average (CWPA) operator to aggregate multiple attribute values of each candidate cadre, thereby obtaining a comprehensive evaluation result based on the CWPA operator. According to reference [26], the definition of the CWPA operator is shown in the figure below. Furthermore, the comprehensive evaluation value of the CWPA operator is given by the total score of the cloud, which can be sorted according to the size of the total score of the cloud, i.e., the sorting result of this operator is based on the total score of the cloud.
同時，CWPA算子中規範式距離T(Zi)和支撐度sup(Zi,Zj)的計算方法也如下圖所示。
At the same time, the calculation methods of the normalized distance T(Zi) and the support degree sup(Zi,Zj) in the CWPA operator are also shown in the figure below.
由于本文采用的不是參考文獻中[26]的區間積分雲模型的基本算子和區間積分雲模型的生成算法，而為實數雲模型，是以該算子采用的雲模型的運算規則如下。并且根據參考文獻[26]，λ取2.
Since this paper does not use the basic operators of the interval-valued cloud model and the generation algorithm of the interval-valued cloud model as described in reference [26], but rather the real-valued cloud model, the operational rules of this operator are as follows. And according to reference [26], λ is set to 2.
本次推文将進行CWPA算子中的規範式距離T(Zi)和支撐度sup(Zi,Zj)的代碼實作，代碼和運作結果如下圖所示。
This tweet will implement the code for the normalized distance T(Zi) and the support degree sup(Zi,Zj) in the CWPA operator, and the code and the running results are shown in the figure below.
四、知識補充——常數根号的表示方法（Knowledge Supplement — Representation Methods of Constant Square Root）
常數根号的表示方法有以下三種：1、打開matlab，在指令行視窗中輸入18^0.5，運作之後看到18求根的結果；2、通過sqrt函數表示根号，在指令行視窗中輸入sqrt(18)；3、通過sqrtm函數表示根号，在指令行視窗中輸入sqrtm(18)。以上三種方法的運作結果，如下圖所示。
There are three ways to represent a constant square root: 1. Open MATLAB, enter 18^0.5 in the command window, and see the result of the square root of 18 after running; 2. Represent the square root through the sqrt function by entering sqrt(18) in the command window; 3. Represent the square root through the sqrtm function by entering sqrtm(18) in the command window. The running results of the above three methods are shown in the figure below.
但是，Matlab中的sqrt函數用于計算一個數的平方根。而sqrtm函數用于計算一個矩陣的平方根。
However, the sqrt function in MATLAB is used to calculate the square root of a number, while the sqrtm function is used to calculate the square root of a matrix.
