8月25日至27日，由贵州省数学学会主办，黔南民族师范学院、黔南州数学学会承办的贵州省数学学会2023年学术年会在黔南民族师范学院召开。来自贵州省高校及科研院所、中小学校的专家学者、一线教师以及学生共300余人云集黔南民族师范学院进行深入学术交流与研讨。
为促进理学院数学与应用数学专业的教育教学改革与发展，提升人才培养质量，加强学术交流，数学与统计学院宁宝权、佘连兵、黄萍、陕振沛、张文林、方秀萍等6人参加本次学术年会。
会上，宁宝权作了题为“MAGDM based on advanced probabilistic dual hesitant fuzzy weighted averaging aggregation operator and score function and its application to online teaching platform supplier selection”的报告。报告指出，This article proposes a new multi-attribute group decision-making (MAGDM) technique in probabilistic dual hesitant fuzzy (PDHF) environments. Firstly, based on the analysis of the shortcomings of existing score function, a new score function is developed for PDHF element, which can better distinguish between two PDHFEs. Meanwhile, we explained in detail the excellent properties of the new score function. Then, considering that the existing PDHF weighted average operator may experience a surge in the number of aggregation results and unreasonable defects during the aggregation process, using the probability splitting algorithm, a novel operation rule for PDHFEs is proposed, and a novel advanced PDHF arithmetic average (APDHFAA) aggregation operator is proposed to overcome the defects of a surge in the number of aggregation results and unreasonable defects. We have studied its excellent properties and provided proof. Thirdly, we propose a novel advanced PDHF weighted average (APDHFWA) aggregation operator. Fourthly, we also propose a new cosine measure in the PDHF environment to select the optimal alternative. Fifthly, we propose a new MAGDM method based on the APDHFWA operator, score function, and cosine measure. Finally, we applied the proposed MAGDM method to address the application problem of online teaching platform supplier selection (OTPSS). The newly proposed MAGDM method can overcome the shortcomings of existing MAGDM methods and effectively distinguish the sorting problem of alternative solutions in certain situations. The newly proposed MAGDM method provides us with a very useful method for processing decision information into PDHFS.
陕振沛教授作了题为“A Group Decision Making Method Based on Interval valued Fermatean Fuzzy Information Integration Operators”的报告。报告指出，针对区间Fermatean模糊信息环境下属性权重信息未知的多属性群决策问题，给出了求解属性权重的公式，并利用定义的区间Fermatean模糊集成算子进行信息集结，构建了群决策模型。通过采矿业可再生能源技术的选择实例说明所提方法的有效性，利用参数对评价结果的影响说明决策方法的灵活性。此外，还将本文方法与现有方法进行了对比分析。
本次学术年会的召开，极大地加强了贵州省数学界的沟通、交流与研讨，为我院师生与省内各大高校及科研院、中小学校提供宝贵的学术交流与分享的机会。（供稿/杨应明 编辑校对/张克 审核/杨光强）
