Operational research is used to solve complex problems in real life, especially to improve or optimize the efficiency of existing systems. The basic knowledge of operational research includes real analysis, matrix theory, stochastic process, discrete mathematics and algorithm basis. Application, mostly related to warehousing, logistics, algorithms and other fields. So operational research and applied mathematics, industrial engineering, computer science, economic management and other related majors.

Second, computational mathematics.

The main contents of computational mathematics include numerical solutions of algebraic equations, linear algebraic equations and differential equations, numerical approximation of functions, solution of matrix eigenvalues, optimization calculation, probability statistics calculation and so on. , as well as the existence, uniqueness, convergence and error analysis of solutions.

Third, applied mathematics.

Applied mathematics majors train students to master the basic theories and methods of mathematical science, have the ability to use mathematical knowledge and solve practical problems with computers, have received preliminary training in scientific research, and can engage in research and teaching in science and technology, education and economic departments or engage in practical application, development, research and management in production, operation and management departments.

Fourth, the financial direction.

This direction mainly trains professionals with a solid theoretical foundation of finance and high application skills, and cultivates students' ability to solve theoretical and practical problems by comprehensively applying the analytical methods of finance, economics, management and modern econometrics, so that students can not only understand the frontier development of international finance, but also adapt to the work of financial management departments, various financial institutions and research institutions.
