燃气爆炸危险性模糊积分评价

本文利用模糊积分对燃气爆炸进行危险性评价，使那些危险性大而权重小的单元通过积分可以产生较大的贡献。文中定义了燃气爆炸的潜在危险性系数和液化气站的潜在危险性指数，通过对某液化气站的调查，得到了组成单元的各因素的潜在危险性系数，并由模糊积分得到单元的潜在危险性系数，进而得到整个液化气站的危险性系数，评价结果较好地反映了该液化气站的安全状况，这种方法也适用于其它方面的评价。

EVALUATION OF TOWN GAS EXPLOSION HAZARDS

In this paper, fuzzy integration method is applied to evaluation of town gas explosion hazards. The effect of the factors with high hazard and low weight is enlarged through integration The potential hazard coefficients and indices are defined. the investigation of a LPG station, the potential hazard coefficients of each facto which compose the element are obtained. As a result the potential coefficient of the whole system by fuzzy integration is obtained. Because the fuzzy integration is defined reasonably the result reflects the situation of the LPG station as a whole. This method can be adapted to other evaluation fields as well.
