Let me answer them one by one: 1. System engineering and modern management is to integrate the system idea into management. System theory first appeared in the fields of automation and electric power. But the idea of system is now also used in enterprise management. You should learn how to build a system model, how to optimize the system and so on. 2. Industrial Engineering and Production Operation Management Industrial Engineering (IE) is a discipline that studies how to improve production efficiency and reduce production costs. For example, learn how to arrange production, even the length of the assembly line and so on. 3. How management science uses scientific methods to engage in management activities is basically to learn operations research and optimization methods. This one is slightly biased towards mathematics, studying how to establish an optimization model and how to apply it to practice. 4. The International School of Engineering Management is undoubtedly the best in the country in its housekeeping skills and strength, and mainly studies activities such as project investment, project supervision, legal disputes, trade disputes and acceptance involved in international engineering issues. 5. Management information system studies how to provide information services for enterprises, including business process reengineering, system analysis and design, and final program implementation. There is also the establishment of enterprise information architecture under distributed conditions, as well as WebService, which requires your computer to have a good foundation. 6. Financial engineering uses quantitative methods to study financial markets. The main tools are time series, stochastic differential equations, stochastic processes and statistics. You are required to be good at computers and mathematics, and have some basic knowledge of finance and finance. That's about it. There may be a problem.
