Abstract

The stock investment selection could be deemed as a classic multiple attribute group decision making (MAGDM) problem involving multiple conflicts and interleaved qualitative and quantitative attributes. Spherical fuzzy sets (SFSs) can excavate the potential vagueness and intricacy in MAGDM more effectively and deeply. This article we propose an integrated decision support system (IDSS) based on SFSs, prospect theory (PT), distance from average solution (EDAS) method and the MEthod based on the Removal Effects of Criteria (MEREC). The proposed IDSS, called SF-PT-EDAS-MEREC model, uses SFSs to describe the uncertain and obscure assessment information of DMs. The combination of PT and EDAS (PT-EDAS) method adequately captures DMs’ psychological behavior characteristics to execute more reasonable alternative evaluation. The MEREC is utilized to efficaciously obtain unknown attribute weights. In addition, this paper also presents a novel score function to compare spherical fuzzy numbers (SFNs) more directly and efficiently. Eventually, in order to illustrate the practicability of the proposed IDSS, two numerical examples of stock investment selection are employed to achieve this. Meanwhile, the comparative study with existing approach further demonstrates the effectiveness and superiority of SF-PT-EDAS-MEREC model.

基于球面模糊pt-edas方法和merc的股票投资综合决策支持系统

股票投资选择可以看作是一个典型的多属性群体决策问题，涉及多个定性和定量属性的冲突和交叉。球面模糊集(SFSs)可以更有效、更深入地挖掘MAGDM中潜在的模糊性和复杂性。本文提出了一种基于sfs、前景理论(PT)、平均解距离法(EDAS)和基于标准去除效应法(MEREC)的综合决策支持系统(IDSS)。提出的IDSS，称为SF-PT-EDAS-MEREC模型，使用SFSs来描述dm的不确定和模糊的评估信息。PT-EDAS结合方法(PT-EDAS)能充分捕捉患者的心理行为特征，进行更合理的替代评价。利用merc算法有效地获取未知属性权值。此外，本文还提出了一种新的分数函数，可以更直接、更有效地比较球面模糊数。最后，为了说明所提出的决策支持系统的实用性，采用了两个股票投资选择的数值例子来实现这一目标。同时，通过与现有方法的对比研究，进一步证明了SF-PT-EDAS-MEREC模型的有效性和优越性。
