摘要
为准确评价非煤矿山安全标准化等级,基于变权理论和物元可拓理论,建立非煤矿山安全标准化评价的变权物元可拓模型。从安全监管、安全保障、安全生产和安全绩效4个方面选取16个因素作为评价指标,运用变权理论确定指标权重,再由待评物元关于各评价等级的贴近度及等级变量特征值得出矿山安全标准化等级,最后通过敏感性分析指出对评价有重要影响的敏感性指标。经计算得出某非煤矿山安全标准化等级为Ⅱ级且偏向于Ⅰ级的程度较大,其中生产工艺系统安全管理是该评价的敏感性指标。研究结果表明:变权物元可拓模型是对传统物元可拓模型的有效改进,能够提高非煤矿山安全标准化评价的准确性。
In order to accurately evaluate standardization grade for non-coal mine safety,a variable weight matter-element extension model of safety standardization for non-coal mines was built based on variable weight theory and matter-element extension theory.Sixteen factors were selected as evaluation indexes in four areas:safety regulation,safety assurance,safety production and safety performance.The variable weight theory was used to determine the weight of evaluation indexes.Then the rankings of mine safety standardization could be determined by the closeness degree of the evaluated elements to each evaluation level and the eigenvalues of rank variables.Finally,sensitivity index that has a significant impact on the evaluation was evaluated through sensitivity analysis.It was calculated that the safety standardization grade of a non-coal mine was GradeⅡand was more inclined to Grade I,and safety management of the production process system was the sensitive index.The results showed that the variable weight matter-element extension model was an effective improvement of the traditional one,which could improve the accuracy of non-coal mine safety standardization evaluation.
