Pythagorean probabilistic hesitant triangular fuzzy aggregation operators with applications in multiple attribute decision making

As a generalization of fuzzy set,hesitant probabilistic fuzzy set and pythagorean triangular fuzzy set have their own unique advantages in describing decision information.As modern socioeconomic decision-making problems are becoming more and more complex,it also becomes more and more difficult to appropriately depict decision makers’cognitive information in decision-making process.In order to describe the decision information more comprehensively,we define a pythagorean probabilistic hesitant triangular fuzzy set(PPHTFS)by combining the pythagorean triangular fuzzy set and the probabilistic hesitant fuzzy set.Firstly,the basic operation and scoring function of the pythagorean probabilistic hesitant triangular fuzzy element(PPHTFE)are proposed,and the comparison rule of two PPHTFEs is given.Then,some pythagorean probabilistic hesitant triangular fuzzy aggregation operators are developed,and their properties are also studied.Finally,a multi-attribute decision-making(MADM)model is constructed based on the proposed operators under the pythagorean probabilistic hesitant triangular fuzzy information,and an illustration example is given to demonstrate the practicability and validity of the proposed decision-making method.

ON PROBABILISTIC NORM OF A LINEAR OPERATORS AND SPACE OF OPERATORS

Since the PN space (E, F) which satisfies condition (PN-5) is just a Menger PN-space (E, F, min), the results with regard to probabilistic norms of linear operators on PN-spaces obtained by Xiao Jianzhong have bigger limitations. In this paper, problems respecting probabilistic norms of linear operators and spaces of operators are studied on more general Menger PN-spaces. The results presented improve and generalize the corresponding results by Xiao.

一种模糊时间序列概率预测方法

在时序预测任务中,历史观测值的不确定性给预测带来了困难。而模糊时间序列预测方法在处理数据不确定性方面具有独特的优势。概率预测则能够提供预测目标的分布情况,从而量化预测结果的不确定性。因此,为了减少不确定性对预测任务的影响,提出了一种基于概率加权策略的模糊时间序列概率预测方法。该方法利用预测目标的历史观测值建立概率加权的模糊时间序列预测模型,通过引入额外的观测值对预测模型的模糊规则库进行细化。在细化过程中,使用2种计算成本较低的算子重构模糊逻辑关系。具体地,交算子用于剔除干扰的信息,并算子则融合所有信息,从而得到2个不同的模糊逻辑关系组集合。当前时刻观测值在2个集合中对应的模糊逻辑关系组即为对下一时刻模糊集的预测,最后经过解模糊输出下一时刻的概率分布。在公开时间序列数据集上验证了该方法的准确性和有效性,与近期提出的PWFTS预测方法相比,预测精度有显著提高。

This thesis aims to propose a novel distance operator,the probabilistic linguistic term ordered weighted distance(PLTOWD)operator,which enriches the distance theory in probabilistic linguistic term circumstances.The PLTOWD operator is an efficient tool to deal with qualitative evaluation information and their corresponding probabilities or importance degrees.Moreover,some of its desired properties and different families of thePLTOWDoperator are discussed.Meanwhile,the extensions of the PLTOWD operator are also investigated.Then,a method of multiple attribute group decision making(MAGDM)in probabilistic linguistic term information is proposed on the basis of the PLTOWD operator.Finally,a numerical evaluation example in public Eco-environment satisfaction is developed to illustrate the practicability and effectiveness of the given method.Some discussions and comparisons are carried out according to the case results.
