This study aims to survey the bibliometric properties of distributed decisions, decentralized decisions, and fuzzy articles published between 1995 and 2023 in the Web of Science (WoS) database. During the analysis process, the keywords “distributed decision, decentralized decision, and fuzzy” were scanned in all languages, both in the titles and the content of all publication types. As a result of the analysis, 79 articles in all fields comprised the dataset. The most used keywords in the articles were related to the distributed decision, decentralized decision, and fuzzy logic, and the most frequently cited publications were examined using the social network analysis method, which uses VOSviewer (version 1.6.19) to visualize the relationships. The study’s goal on “active researchers, active journals, journal metrics, title document type, active countries, and active institutions” was to look at the words most frequently used in articles on distributed, decentralized, and fuzzy logic. The social network analysis represented the relationships between these keywords and the most frequently cited publications. The findings demonstrated a significant correlation between using these keywords in academic literature and their contribution to this field’s research. These results can assist researchers in finding potential partners and keeping up with current research trends. Overall, this study offers important new perspectives on the state of research on fuzzy logic, distributed decision making, and decentralized decision making.

The progress of communication technology and the Internet has made the dual-channel supply chain have great development. Supply chain members have to compete and cooperate with other enterprises on the chain in order to obtain greater self-benefit. In the competitive-cooperative relationship among enterprises, price discrimination and sales effort are common tools of operation, and Nash equilibrium theory is a common strategy in the process of supply chain game. Whether manufacturers can promote retailers to implement sales efforts through price discrimination and ensure that the overall revenue of the supply chain is improved at the Nash equilibrium is great significance to both the supply chain and individual enterprises. This paper constructs a decentralized dual-channel supply chain mathematical model composed of an independent manufacturer, an offline retailer, and an online retailer, taking into account the impact of the offline retailer’s sales efforts on his demand and its positive external for the other channel. The revenue matrix of retailers’ decisions about whether or not to pay their sales efforts is built under the condition that manufacturers charge different wholesale prices to different retailers and solves the condition of every decision combination becoming the Nash equilibrium using the Nash equilibrium game theory. Finally, the optimal pricing strategy of the manufacturers is analysed to get the constraints of this dual-channel supply chain achieving Pareto improvement when manufacturer uses wholesale price discrimination strategy.
通信技术和互联网的进步使得双渠道供应链有了长足的发展。供应链成员为了获得更大的自身利益,不得不与链上其他企业展开竞争与合作。在企业间的竞争合作关系中,价格歧视和销售努力是常用的操作手段,纳什均衡理论是供应链博弈过程中常用的策略。制造商能否通过价格歧视促进零售商实施销售努力,确保在纳什均衡时提高供应链的整体收益,对供应链和单个企业都具有重要意义。本文构建了一个由独立制造商、线下零售商和线上零售商组成的分散双渠道供应链数学模型,考虑了线下零售商的销售努力对其需求的影响及其对另一渠道的正外部性。在制造商对不同零售商收取不同批发价的条件下,建立了零售商决定是否支付销售努力的收益矩阵,并利用纳什均衡博弈论求解了每个决策组合成为纳什均衡的条件。最后,分析了制造商的最优定价策略,以获得当制造商采用批发价格歧视策略时,该双渠道供应链实现帕累托改进的约束条件。

Advancement in mobile phone (MP) technology has revolutionized the lifestyle. In recent years, we observed that MP technology had been involved in almost all aspects of life, such as communication purposes, e-commerce, mobile baking, and social media connectivity. So, it becomes a hot research topic to select the best MP that fulfills the desired feathers requirement. In this paper, the expert’s familiarity with the examined objects is factored into the initial judgments under the T-spherical fuzzy sets (T-SFSs) environment. The T-SFS is the extension of the picture fuzzy (PF) set (PFS), which gives wider scope for finding the most precise options than existing fuzzy frameworks. The multiattribute decision-making (MADM) is a common and valuable method for aggregating information. For MADM, various aggregation operators (AOs) have been created over the years. The article introduces the newly proposed approach T-spherical fuzzy (T-SF) confidence level weighted averaging and T-SF confidence level weighted geometric . Also, some desired properties of AOs are discussed, and the T-SF entropy measure is introduced for selecting the weight criteria. A MADM framework is introduced, on the behalf of proposed operators. The proposed MADM framework is applied to solve the real-life example of consumers’ preferences to show effectiveness and practicality. Lastly, the developed framework is set side by side with other prevailing approaches to demonstrate the superiority and significance of other existing AOs.
移动电话(MP)技术的进步彻底改变了人们的生活方式。近年来,我们发现 MP 技术几乎涉及生活的方方面面,如通信、电子商务、手机烘焙和社交媒体连接等。因此,如何选择能满足所需羽毛要求的最佳 MP 就成了一个热门研究课题。本文在 T-球形模糊集(T-SFS)环境下,将专家对被检对象的熟悉程度作为初始判断的因素。T-SFS 是图片模糊(PF)集(PFS)的扩展,与现有的模糊框架相比,它能为找到最精确的选项提供更广阔的空间。多属性决策(MADM)是一种常用且有价值的信息聚合方法。针对 MADM,多年来出现了各种聚合算子(AOs)。文章介绍了新提出的 T 球形模糊(T-SF)置信度加权平均法和 T 球形模糊置信度加权几何法。此外,文章还讨论了 AOs 的一些理想特性,并引入了用于选择权重标准的 T-SF 熵度量。还介绍了代表拟议算子的 MADM 框架。提出的 MADM 框架被应用于解决消费者偏好的实际案例,以显示其有效性和实用性。最后,将所开发的框架与其他主流方法并列,以证明其他现有 AO 的优越性和重要性。

Asymmetric Impact of Heterogenous Uncertainties on the Green Bond Market 异质性不确定性对绿色债券市场的不对称影响

Investing in green bonds has been recognized as a strategy that not only promotes environmental performance but also offers attractive investment returns. However, macroeconomic factors, such as geopolitical risk (GPR), climate policy uncertainty (CPU), and global economic policy uncertainty (GEPU), play a substantial role in shaping green bond returns. Using the returns of US green bonds as a proxy for the returns of green bonds, we argue in this paper that these heterogenous uncertainty measures might have asymmetric impacts on the returns of green bonds (GB). By employing monthly data from January 2016 to August 2022, we apply the nonlinear autoregressive distributed lags model (NARDL) to examine the asymmetric impact of these heterogenous uncertainty measures on the returns of GB. The NARDL findings reveal evidence of short-run asymmetric impacts of GPR, GEPU, and CPU on the returns of green bonds. In the long run, there is an asymmetric impact of GPR and CPU on the returns of GB. However, there is a symmetric impact of CPU on the returns of GB in the long run. Specifically, in the short run, we found that a positive CPU shock causes a decline in the returns of green bonds. A similar magnitude of negative CPU shock causes an increase in the returns of green bonds. Moreover, a positive shock to GPR increases the return of green bonds, while a comparable negative shock to GPR reduces the return of GB. Furthermore, only negative shocks to GEPU have an impact on GB returns in the short run. Specifically, a negative GEPU shock reduces GB returns. In the long term, the returns of GB are positively impacted by negative shocks in GPR and both positive and negative shocks in GEPU, whereas positive shocks in GPR affect the returns of GB negatively.
投资绿色债券已被公认为是一种不仅能促进环境绩效,还能提供诱人投资回报的策略。然而,地缘政治风险(GPR)、气候政策不确定性(CPU)和全球经济政策不确定性(GEPU)等宏观经济因素在影响绿色债券收益方面发挥着重要作用。本文以美国绿色债券的收益率作为绿色债券收益率的替代指标,认为这些异质性的不确定性指标可能会对绿色债券(GB)的收益率产生不对称的影响。通过采用 2016 年 1 月至 2022 年 8 月的月度数据,我们运用非线性自回归分布滞后模型(NARDL)检验了这些异质性不确定性指标对绿色债券收益的非对称影响。非线性自回归分布滞后模型的研究结果表明,GPR、GEPU 和 CPU 对绿色债券收益率的短期影响不对称。从长期来看,GPR 和 CPU 对绿色债券收益的影响是不对称的。但从长期来看,中央政策组对绿色债券收益的影响是对称的。具体来说,在短期内,我们发现中央处理器的正向冲击会导致绿色债券收益率下降。类似幅度的中央政策组合负向冲击会导致绿色债券收益率上升。此外,对 GPR 的正向冲击会增加绿色债券的收益,而对 GPR 的类似负向冲击则会降低 GB 的收益。此外,只有 GEPU 的负向冲击才会在短期内对 GB 的回报率产生影响。具体来说,GEPU 的负向冲击会降低 GB 的回报率。从长期来看,绿色增长收益率的负向冲击以及绿色就业单位的正向和负向冲击都会对绿色增长收益率产生积极影响,而绿色增长收益率的正向冲击则会对绿色增长收益率产生消极影响。

We focus on fault-tolerant consensus for heterogeneous dynamics systems with static and dynamic leaders under input saturation in this article. We apply theory of finite-time stability to multiagent system cooperative control. Also, we use integral sliding mode to overcome disturbance. The primary goal is a set of second-order linear and second-order nonlinear agents moving along the leader’s trajectory. We use topology graph to describe communication between multiple agents. By using integral sliding mode control way, corresponding controller is introduced to make system stable. Finally, correctness of experiment was confirmed by MATLAB numerical simulation.
