On the morning of December 14, the 21st Issue of the 21st Century, we were honored to invite Professor Wu Jian from the School of Economics and Management of Shanghai Maritime University to deliver an academic report entitled "Group Consensus Decision-making Based on Social Network Trust". Professor JU YanBING, Department OF Management Engineering, School OF Management and Economics, Beijing Institute of Technology, presided over the report. Affected by the epidemic, this report was conducted online. Some teachers and graduate students of the School of Management and Economics attended the report.
In the report, Professor Wu Jian combined with his research results over the years, and thoroughly explained the group consensus decision-making problem based on social network trust from the aspects of research problem extraction, trust-based feedback mechanism, trust-based anti-operation consensus, example analysis, conclusion and outlook. Professor Wu Jian first analyzed the defects of the traditional group consensus: the static method is used to gather user preferences without considering the interaction between group members, which can not improve the satisfaction of the group and the accuracy of recommendation. Then, in view of the shortcomings of traditional consensus decision-making methods, the importance of exploring group consensus decision-making based on social network trust is pointed out, and the trust-based feedback mechanism and trust-based anti-operation consensus in group decision-making are deeply analyzed. Finally, an example is given to illustrate the practicability and effectiveness of the group consensus decision-making method based on social network trust, and the future research directions are given.
After the report, Professor Wu Jian had an in-depth discussion with Professor Ju Yanbing, Professor Hou Fujun, Professor Cui Lixin, Associate Professor Zhu Bin, Associate Professor Gao Huiying, Associate Professor Zhang Bin, Assistant Professor Ding Cushii and other students of the School of Management and Economics on issues related to the report. All the teachers and students attending the meeting said that they benefited a lot from the report and hoped to have further exchanges with Professor Wu Jian offline after the epidemic.
