本期继续为大家带来的论文是《基于可信度的基本不确定区间犹豫模糊广义 TODIM 应急群决策方法》，作者梁薇，王应明 。本期推文将从思维导图，精读内容，知识补充进行学习。

The paper brought to you in this issue is "Basic Uncertain Interval Hesitant Fuzzy Generalized TODIM Emergency Group Decision-Making Method Based on Credibility" by Liang Wei and Wang Yingming.In this post, we will learn from mind mapping, close reading and knowledge supplement.

本周小编带大家学习一下文章的引言部分，首先是我们的学习框架——思维导图：

This week we will take you to learn the summary of the article, the first is our learning framework - mind map:

1. 知识获取 1. Knowledge acquisition

从文章内容上分析相较区间犹豫模糊集而言，作者认为其所提出的基本不确定区间犹豫模糊集增加考虑了确定度维度，以衡量评价信息的质量及决策者的可靠程度。作者为进一步说明本文所提方法的有效性和优越性，在文中将与传统的区间犹豫模糊多属性决策方法进行对比分析研究的适用性。决策步骤如之前分析的类似，考虑到区间犹豫模糊集忽略了确定度，因此犹豫度计算由作者文章公式获得。得到总优势度为:

Compared with the interval hesitancy fuzzy set, the author thinks that the basic uncertainty interval hesitancy fuzzy set has taken into account the dimension of certainty, so as to measure the quality of evaluation information and the reliability of decision makers.In order to further illustrate the effectiveness and superiority of the proposed method, the applicability of the proposed method is compared with the traditional interval hesitation fuzzy multi-attribute decision making method.The decision steps are similar to the previous analysis. Considering that interval hesitation fuzzy sets ignore the certainty, the hesitancy calculation is obtained from the formula in the author's paper.The total dominance is obtained as follows:

根据计算两个不同方法的计算结果所示，可以明显看出基于区间犹豫模糊集的决策方法与本文所提出的方法得到的排序结果不同。作者有分析这个情况的发生，他认为区间犹豫模糊集仅仅只考虑到了决策专家的犹豫性和模糊性，但忽略了决策专家所提供的信息质量及可靠性程度，从而在计算可信度时与其提出的方法产生了一定的偏差。作者研究出的基本不确定区间犹豫模糊集在区间犹豫模糊集的基础上增加了确定度维度，相对于传统的区间犹豫模糊集而言，增加考虑了决策专家对于评价信息的确定程度，有效衡量了信息的质量。因此相对比来说作者的文章采用的信息表达方式考虑更加周全，同时也更适合不确定的决策环境。

According to the calculation results of two different methods, it is obvious that the decision method based on interval hesitation fuzzy set has different sorting results from the method proposed in this paper.The author has analyzed the occurrence of this situation, and he thinks that interval hesitation fuzzy set only considers the hesitation and fuzziness of the decision expert, but ignores the quality and reliability of the information provided by the decision expert, so there is a certain deviation in the calculation of credibility with its proposed method.The basic uncertainty interval hesitating fuzzy set developed by the author adds the dimension of certainty on the basis of interval hesitating fuzzy set. Compared with traditional interval hesitating fuzzy set, the author also takes into account the degree of certainty of decision-making experts for evaluation information and effectively measures the quality of information.Therefore, comparatively speaking, the information expression method adopted by the author is more comprehensive and more suitable for the uncertain decision-making environment.

2. 知识补充 2. Knowledge supplement

决策的形式特征有哪些？

1．按决策的作用分类

战略决策；管理决策；业务决策

2．按决策的性质分类

程序化决策 ；非程序化决策

3．按决策的问题的条件分类

确定性决策；风险型决策；不确定型决策

What are the formal characteristics of decision making?

1.Classified by the role of the decision

Strategic decision;Management decision;Business decision

2.By the nature of the decision

Programmed decision making;Non-procedural decision making

3.Categorize by the conditions of the problem being decided

Deterministic decision making;Risk-based decision making;Uncertain decision making

应急决策的特点？

（1)随着智能终端的爆炸式增长，“自媒体”的出现大大增加了应急决策数据源的多样性和复杂性。信息传递不再受传统决策权力核心自上而下的控制，也不再依赖于“金字塔式”的逐层收集、分步收敛和严格过程的方式，而是同时具有自下而上和多点分散的传递路径。同时，应急管理本质上是一个复杂的多目标优化问题。

（2）应急决策是一个多主体、多阶段、多层次的适应性动态演化过程。

（3）应急决策是非常规的、多目标的、紧急的、有限的、实时的和动态的。对应急决策的体制、制度、机制和流程提出了新的要求。

What are the Characteristics of emergency decision-making?

(1) With the explosive growth of intelligent terminals, the emergence of "we media" has greatly increased the diversity and complexity of emergency decision-making data sources.Information transmission is no longer controlled from the top down by the traditional decision-making power core, nor is it dependent on the "pyramid-style" way of layer by layer collection, step by step convergence and strict process, but has both bottom-up and multi-point decentralized transmission paths.At the same time, emergency management is essentially a complex multi-objective optimization problem.

(2) Emergency decision-making is a multi-agent, multi-stage and multi-level adaptive dynamic evolution process.

(3) Emergency decision-making is unconventional, multi-objective, urgent, limited, real-time and dynamic.New requirements are put forward for the system, system, mechanism and process of emergency decision-making.
