基于权重博弈层次分析法的火灾参量评价

Fire parameters evaluation based on weighted game analytic hierarchy process

发生火灾时,会出现烟雾、高温、火焰和燃烧气体等火灾特征。不同可燃物质或相同物质在不同环境条件下燃烧时,火灾特征信号均会产生较大差异。为了选出有效火灾参量或组合作为火灾检测并及时报警的依据,提出了权重博弈层次分析法对火灾参量及组合进行评价。层次分析法中的指标权重对评价结果起着关键性作用。传统确定权重的方法是通过判断矩阵计算得到的,存在过分依赖专家经验的问题。利用博弈论对判断矩阵得到的权重和结构熵权法得到的权重进行综合,可以提高权重计算结果的可靠性。结果表明:烟雾、温度、CO复合参量综合评分最高,这3种火灾参量可以实现优势互补,有效识别不同类型火灾,并且不易受环境干扰。

When fire occurs,there may be fire characteristics such as smoke,high temperature,flame and combustion gas.When different combustible substances are burned or the same substances are burned under different environmental conditions,the fire characteristic signals may be greatly different.In order to select effective fire parameters or combinations as the basis for fire detection and timely alarm,the analytic hierarchy process(AHP)of weighted game was proposed to evaluate the fire parameters and combinations.The index weight in AHP played a key role in the evaluation results.The traditional method to determine the weight was obtained by calculating the judgment matrix,which had the problem of over-reliance on the expert experience.The reliability of the obtained weight matrix can be improved by using game theory to synthesize the weights obtained by judgment matrix and structure entropy weight method.The results showed that the composite parameters of smoke,temperature and CO have the highest comprehensive score.These three fire parameters can complement each other,effectively identify different types of fire,and are not vulnerable to environmental interference.
