基于灰色关联分析的爆破效果综合评价

Comprehensive evaluation of blasting effect based on grey correlation analysis

针对传统灰色关联分析模型权重分配和确定存在的不足,提出了灰色关联分析和层次分析相结合的爆破效果评价模型。该模型对加权灰色关联度进行了改进,通过改进的标度矩阵法确定权重的大小,避免了权重赋值的主观性,利用权重的形式体现各评价指标对评价目标的影响程度,同时采用两层灰色关联分析评价模式,并进行了实例分析,结果表明:该模型不仅简化了评价系统,而且评价结果更科学、合理。

Considering that traditional grey correlation analysis model has some deficiency in decision and distribution of weight, a new evaluation model which combines grey correlation analysis with level analysis is presented. The model improves weighted grey correlation, uses improved demarcating matrix method to determine weigh in order to avoid subjective factor, and embodys the influence extent of each estimation index to evaluation object by weight form, moreover two layers grey correlation analysis is adopted.Practices indicate that this model not only reduces estimation system but also makes estimation result more scientific and rational.
