层次分析法在电解锰工艺中的应用

利用低品位软锰矿与高硫煤生产电解锰是一种新兴的资源化生产电解锰的新工艺。结合层次分析法确定权重的优势提出基于层次—灰色关联分析法的评价方法,建立传统电解锰工艺生产与低品位软锰矿与高硫煤互补资源化生产电解锰方案比选的优化模型,进行方案优选。同时在确定各评价指标权重时,引入了三标度法,利用三标度AHP方法确定各评价指标权重,通过准则层关联度及综合关联度的定量分析各方案实施对社会经济系统、资源系统以及环境系统的影响,证实本体系新工艺生产电解锰明显优于传统工艺。

Application of AHP in the System of Integrated Utilization of High-sulfur Coal and Low-grade Pyrolusite

The method of using high - sulfur coal and Low-grade pyrolusite to produce manganese is a new process. This article takes advantages of AHP and proposes a new way to research this system. This pa- per also builds a model of this system in order to compare with the traditional one. It could make readers un- derstand its advantages easily. Meanwhile, this paper use three-scale method to determine the proportion. It could reduce the factor of human speculation in the whole process. So it lays a good foundation to make a reasonable decision. Use AHP to determine the three-scale weight of each index and analysis the pact of this system in respect of social-economic, resource and environment. Finally, it is confirmed that the new tech- nology is superior to the traditional manganese .
