基于改进突变级数法的矿井通风系统改造优化研究

为了科学有效地对矿井通风系统改造优化方案进行决策,提出了基于突变理论和熵权值的改进突变级数法。首先,对矿井通风系统改造优化方案的评价目标进行层次分解;其次,将最底层评价指标进行无量纲归一化处理;再次,利用熵权法计算其相应的熵权值,确定各评价指标的相对重要性;最后,依据相应的突变模型的归一公式进行逐层向上计算,得出突变级数值,进而确定出最优方案。实例研究表明,该方法不但可避免人为确定权重的主观性,而且计算简单、可靠性高,评价结果更趋于实际。

In order to select the optimization program of mine ventilation system scientifically and effectively,an improved catastrophe progression method based on catastrophe theory is put forward.First,the evaluation objectiveof the optimization of mine ventilation system transformation program is decomposed multi-levelly,secondly,non-dimension of the underlying evaluation index is done.thirdly,determine the relative importance of each index by calculating the entropy weight of each index by using the entropy method,then using the normalization formula of the corresponding mutation model layer by layer to the catastrophe progression value,and then determine the optimal solution.The case study shows that this method can avoid the subjectivity of weight determination,and has the advantages of simple calculation and high reliability.
