基于改进AHP-未确知测度理论的选矿厂防尘工程评价模型及应用

Evaluation model based on improved AHP-unascertained measure theory for concentrator dust prevention engineering and its application

选矿厂防尘工程评价涉及多因素,采用层次分析法和未确知测度理论相结合的理论模型对某有色金属矿山选矿厂防尘工程进行评价。从防尘工艺、作业环境与卫生、组织与管理水平和防尘设备等4方面22个指标建立综合评价指标体系,以专家打分的形式获得指标测度矩阵,基于置信度识别准则获得该选矿厂防尘工程评价等级为好,与实际调查结果一致。该模型具有一定的合理性与应用价值。

The evaluation of concentrator dust prevention engineering involves many factors. So a theory model based on AHP and unascertained measure theory was used to evaluate the concentrator dust prevention engineering in a non-ferrous metal mine. A comprehensive evaluation system was established based on 22 indicators from 4 aspects including dust prevention technology,working environment and health,organization and management level and dust prevention equipment. The index matrix was obtained by expert rating and the dust prevention engineering of the concentrator was rated good according to the credible degree recognition criteria,which was consistent with the results of field investigation. The model is reasonable to some extent and has certain application value.
