Our mathematics discipline was established in 1986. In 1990, it was granted the authority to confer master's degrees in Applied Mathematics, followed by the authority to award master's degrees in Operations Research and Cybernetics in 1996 and the right to confer doctoral degrees in Operations Research and Cybernetics in 2003. In 2005, it gained the authority to award master's degrees in the first-level discipline of Mathematics. In 2009, it was approved to establish a postdoctoral programme for the first-level discipline of Mathematics, and in 2010, it was granted the authority to confer doctoral degrees in the first-level discipline of Mathematics. In 2010, Information Operations Research was recognized as a key interdisciplinary discipline in Beijing. In 2015, it was awarded the National 111 Innovation and Talent Introduction Base for Information and Transportation Operations Research. The mathematics discipline entered the top 1% of the ESI world rankings for the first time in 2022 and was included in the 2022 "ShanghaiRanking's Global Ranking of Academic Subjects" list. It also made the shortlist for the 2022 U.S. News World University Subject Rankings and ranked between 351st and 400th in the 2023 QS World University Rankings by Subject (24th to 26th among universities in the Chinese mainland).

The discipline currently has 54 full-time faculty members, including 17 professors and 25 associate professors. Among them, there is one recipient of the National Science Fund for Distinguished Young Scholars, one National Outstanding Young University Teacher, two recipients of the special government allowance, and one Beijing Young Teaching Excellence Award winner.

Since the 14th Five-Year Plan, the mathematics discipline has made significant progress in areas such as discipline development, scientific research, talent cultivation, and laboratory development. In 2021, it secured one international (regional) cooperation and exchange project. In 2023, it was granted one key project by the National Natural Science Foundation of China. In 2024, it was approved for one National Science Fund for Distinguished Young Scholars project.

In response to the major theoretical challenges facing the discipline of mathematics, and particularly aligned with the university's specialized fields of transportation, information, and management, the discipline has, through long-term exploration and practice, established five distinctive research directions including combinatorial theory, algebraic graph theory, differential equations, coding theory and algorithms, and basic mathematics.
