Optimization method of interval-valued decision and its application——The 52nd Business School Teacher Development Center Forum held successfully

On the morning of December 1, the business school held the 52nd session of the Teacher Development Center Forum in the lecture hall 228 of Xingmin. Professor Dengfeng Li was invited to be the keynote speaker of the lecture, which bringing a wonderful lecture on the theme of "interval value decision-making optimization method and its application" to the teachers and students of our college. Professor Junhong Bai, the vice president of the business school, presided over the activity, and a number of teachers and postgraduate students of the business school participated in the lecture.
