Abstract: Principles of systems engineering is an interdisciplinary graduate course that cultivates students' ability to use“holistic”or“systematic”thinking to scientifically analyze complex engineering and solve problems. Students should have experience and ability in engineering before studying. Given the mismatch between students' current abilities and the abilities required by the course, the teaching effect is not good; to improve this situation, this paper proposes to optimize the teaching content of principles of systems engineering and adopt the“trinity”course optimization method, which starts from the existing knowledge reserve, combines the development needs of the information age and organically combines with the big science and engineering, to achieve high-quality teaching.

Key words: Principles of systems engineering, Optimization of teaching content, Teaching in practice, Methodology of systems, Big data forecasting, FAST engineering
