影响因素交叉作用下煤矿企业环境评价

Environmental Assessment of Coal Mining Enterprises under the Interactions of Affecting Factors

通过煤矿企业环境影响因素交叉作用有向图构建邻接矩阵,采用Matlab迭代计算可达矩阵,建立环境影响因素交叉作用下结构模型,采用超矩阵模型确定准则层和指标层权重,最后通过在某煤矿企业实证应用。结果表明:影响因素交叉作用采用的可达矩阵和划分方式可以准确确定其结构模型,关系矩阵模型有效解决影响因素交叉作用下各影响因素的权重确定,对煤矿企业环境评价有一定指导意义。

A directed graph adjacency matrix was built through the cross reactions of environmental factors and thestructural model was constructed with the Matlab iteration to calculate the reachable matrix. Then the criteria and indexweights were determined using super - matrix model. And finally it was applied in a coal mining enterprise. The resultsshowed that the structural model could be determined accurately by the reachable matrix and method of classification inthe interactions of impact factors and that super - matrix model could obtain the weights of each factor. It provided acertain guiding significance for the environmental assessment of coal mining enterprises.
