This course introduces the main concepts and techniques in the establishment and operation of a system. It aims to develop students' analytical and innovative skills, and the ability to use system thoughts and methods to address complex problems. Students will first learn the classification and development of the system engineering, study its main principles and methodology of the system engineering, and understand the application value of the system engineering. System design exists in each stage of the development and maintenance of a system, while the system analysis is the basis of system design. Therefore, this course will also introduce the basic procedures of system analysis and design and presents some commonly used system evaluation methods. System maintenance and modification are key elements of the system operation. The basic steps, system implementation skills and risk precautions in the system management will be introduced in this course. Meanwhile, students will also learn the widely-used techniques in system modeling and simulation, such as the mathematical simulation and the computer simulation. In addition, students will also learn the knowledge about the system decision-making and optimization. Currently, as the system is gradually becoming more complex, large-scale, and multiobjective, traditional optimization techniques are becoming increasingly overwhelmed. Therefore, this course will also introduce some advanced intelligent optimization techniques and multiobjective optimization decision-making techniques.
