Safety system engineering is a method of using system engineering to identify, analyze and evaluate the hazards in the life cycle of a system. ? According to the results, it adjusts the process, equipment, operation, management, production cycle, investment and other factors to control the possible accidents, so that the system is in the optimal security state. Three subsystems: Human subsystems Machine subsystems Environment subsystem object of safety system engineering These three interrelated, mutually constrained, interactive subsystems constitute an anic whole of a humanmachineenvironment system. Analysis, evaluation, control human machine environment system security, can really solve the system safety issues. contents of safety system engineering The basic task of safety systems engineering is to predict, evaluate and control hazards. The analysis process can be summarized as follows: System safety analysis (identification and forecasting hazards)。Safety EngineerinⅠg NASA39。
