| Abstract: |
| Objective To propose an improved weight determination method for safety evaluation of aerial oxygen and nitrogen station. Methods Based on constructing a safety evaluation indicator system of an aerial oxygen and nitrogen station, AHP and entropy method were used comprehensively to combine subjectivity and objectivity of influencing factors, to obtain the comprehensive weight of each indicator. Results After comparing this result with that obtained by other 4 methods such as entropy weight method, APH, etc., this method was more applicable and can improve the creditability of results. Conclusion Through an example analysis of one aerial oxygen and nitrogen station, this method is objective and reasonable, it could be used as a judgment basis for risk control on protection of the four stations. |
