2022年11日27日，受聊城大学数学科学学院邀请，加拿大里贾纳大学姚一豫教授在线上作了题为“Research Methodology based on Three-way Decision”的学术报告。此次报告由数学科学学院姚炳学教授主持，聊城大学、西北师范大学、重庆邮件大学和临沂大学等4所高校的30多位师生参加了本次报告会。
姚一豫教授从哲学、方法论和应用等多个方面、多个视角和多个层次介绍了三支决策的基本思想，并指出了三只决策未来可进一步思考的课题。最后，姚教授和与会师生进行了30多分钟的交流、讨论。通过此次报告会，大家对三支决策的理论与应用有了更为深刻的认识，为从事这方面工作的师生指明了研究方向。
