灰色关联度-DTOPSIS法在煤矿事故分析中的应用

摘要

针对煤矿事故起数和事故死亡人数对煤矿安全的影响，传统的事故分析方法很难对各因子的影响程度做出科学全面的定量解释。利用灰色关联度和DTOPSIS法相结合的方法，可有效避免DTOPSIS法中指标权重的主观赋予性和灰色关联度中数据处理的缺陷，更加客观、真实可靠地反映实际情况，并与传统方法作比较，其结果证明了灰色关联度-DTOPISIS法的科学性和适用性，为煤矿安全提供了依据。%According to the effect of coal mine accidents and deaths to mine safety, it is dififcult to make a scientiifc and comprehensive quantitative explanation to the influence degree of each factor by the traditional method of accident analysis. Combining the gray relational degree and DTOPSIS method to effectively avoid the subjective property of the index weight in the DTOPSIS method and the defects of data processing in the gray relational degree, relfect the actual situation objectively, truly and reliably. Compared with the traditional method, it shows the scientiifc and applicability of the gray relational degree –DTOPISIS method, and provides the basis for coal mine safety.
