基于RS—SVM的瓦斯爆炸危险源评价模型

根据危险源理论和评价指标选择原则,建立了瓦斯爆炸评价指标体系。基于粗糙集(RS)理论、支持向量机(SVM)方法和瓦斯爆炸的特点,建立了基于RS—SVM的瓦斯爆炸危险源评价模型。应用该模型对具体样本数据进行安全评价,得出安全评价等级。RS—SVM评价方法能够实现动态的安全评价,对提高安全评价技术水平具有现实参考作用。

Safety Assessment Model for Gas Explosion Hazard Source based on RS-SVM

An assessment index system for gas explosion was set up according to the theory of hazard source and the selection principle of the assessment index. A RS-SVM-based assessment model for gas explosion hazard source was also established according to the theory of Rough Set (RS), the principle of Support Vector Machine (SVM) and the characteristics of gas explosion. The safety assessment on the specific sample data was carried out with this model and the grade of safety assessment was thus obtained. RS-SVM method can realize dynamic safety assessment, so it is helpful for the improvement of the safety assessment technology.
