Abstract: Safety system engineering is an interdisciplinary subject developed based on system engineering,covering many disciplines such as economy,management,system engineering,etc.Its development is a dynamic process.In order to study the application and development trend of safety system engineering in China in recent ten years,Based on bibliometrics,this paper makes a search and analysis on the literature of safety system engineering of public database (CNKI) in latest ten years (20102019) with the theme of "safety evaluation,safety assessment,safety management,risk management,risk assessment,risk analysis,risk evaluation and risk control",and analyzes the application situation and development trend of safety system engineering,and makes a statistical analysis of the research methods of safety system.According to the statistical analysis of literature,the main application of safety system engineering in China is safety evaluation and management,risk assessment and management,and the main method is safety evaluation method.According to the current situation of discipline development,the author puts forward the methodology research of safety system,optimization of the system method,and the development direction of system simulation and analysis.Applies the safety system engineering to the design of engineering project extensively,and provides the basis for project decision and risk control,and finally achieves the goal of system optimization.

Key words: safety systems engineering,public databases,bibliometrics,applications and development
