摘要
为了实现矿井通风的系统安全,对系统的安全性进行定性、定量的预测分析和安全评价,将多目标决策中的逼近理想解排序方法TOPSIS引入到矿井通风系统方案优化的评价之中,将技术、经济、安全3个方面作为评价标准,提出了矿井通风系统评价的指标体系,建立了基于熵权的多层次TOPSIS评价模型,并结合实例验证其准确性和优越性。结果表明,该方法利用灰熵理论确定评价指标的权重——熵权,避免了权重确定中的主观性和计算复杂性;借助评价对象与理想解和负理想解的距离确定的加权相对接近度作为评价准则,避免了评价模型的主观性,使评价结果更符合生产实际。
In order to realize system safety of mine ventilation, a qualitative and quantitative pre-measurement analysis and safety assessment were conducted for the system safety. The approximated ideal explanation sequence method TOPSIS in multi target decision had been introduced to the assessment on the optimized plan of the mine ventilation system. Taking the technology, economy and safety as the assessment standards, the paper provided the index system for the assessment of the mine ventilation system. A multi layer TOPSIS assessment model was established based on the entropy power and the accuracy and superiority of the model were conformed with the practical cases. The results showed that the method with gray entropy theory to set the weight entropy power of the assessment indexes could eliminate the subjectivity and calculation complexity in the weight set. With the distance between the assessment object and the ideal explanation and negative ideal explanation, the weight relative proximity was confirmed as the assessment code, which could eliminate the subjectivity in the assessment of the model and could make the assessment results more closed to the actual production.
