2. Based on the present methods, fully knowing about the research methods at relevant field, starting with analytical method, put forward the ensemble theory framework of FSA, emphasize on the analysis of the technological process for hazard identification and risk assessment.
In order to guarantee the reliability and security of the microsurgery robot system, the idea of applying the HISIC (hazard identification and safety insurance control) and FTA (fault tree analysis) safety analysis methods to the system design is put forward.
According to the demand of surgery environment and surgical operation, the authors make the research on how to use the following sequence: system demand analysis, hazard identification, safety insurance control, safety critical limits, satety monitoring control, verification and validation, system log and documents as the guide of the system design, and also make the research on how to use the fault tree and fault function to analyze the conclusion of design.
By contraposing characteristics of warship and combining with warship safety requirement analysis,working items and implementation procedure of warship safety analysis is provided,hazard analysis and risk evaluation method is presented, and working charts of hazard recognition and hazard analysis for warship safety analysis is presented.
Danger discrimination and assessment in production process is related to personal safety and equipment safety. It is best not to sum up and analyze the accident after it happened but to discriminate and assess the danger befor it occur.
