基于熵权法-AHP法航空制氧制氮站安全评价指标体系权重确定方法研究

目的提出一种改进的航空制氧制氮站安全评价权重确立的方法。方法在构建航空制氧制氮站安全评价指标体系的基础上,综合利用层次分析法、熵权法的优点,将影响因素的主观性与客观性相结合,最后得出各指标综合权重。结果将本文方法所得权重与熵权法、AHP法等4种方法所得结果进行比较,本方法适用性更高,可提高评价结果的可信性。结论通过对某制氧制氮站保障实例分析,该方法客观合理,可为航空四站保障风险控制提供判断依据。

Weight Determination of Safety Evaluation Indicator System of the Aerial Oxygen and Nitrogen Station Based on AHP-Entropy Weight Method

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.
