开拓系统优化的AHP-熵权法和灰色关联分析

Development System Optimization based on AHP-entropy Weight Method and Grey Correlation Analysis

开拓方案的选择对地下矿山开采具有关键性的作用,而影响开拓方案选择的因素众多,且影响程度不一。为避免个人主观认识差异及客观数据之间关系的片面性对开拓方案选择结果的影响,提出了基于AHP-熵权法和灰色关联分析的开拓系统评价方法。在评价过程中,综合考虑了影响开拓方案选择的定性、定量指标,将AHP法和熵权法结合,确定了评价指标的综合权重,通过灰色关联分析得到了最优开拓方案。矿山实践表明:该方法得出了可靠评价指标权重及评价结果,且计算过程简单,评价结果直观,是一种科学合理的评价方法,为开拓方案的优化选择以及其他系统工程的多方案优选提供了一条新的途经。

Selection of mine development scheme plays a key role in underground mining,and the factors influencing the development scheme are numerous with different influence level. In order to avoid the influence of personal subjective understanding differences and respective relations between objective data to the result of the development scheme selection,the development evaluation method based on AHP and entropy weight method and grey correlation analysis is proposed.In the process of evaluation,the qualitative and quantitative indicators which affect the development scheme selection are considered,and the comprehensive evaluation index weight is determined in combination with the AHP method and entropy weight method,and the optimal development scheme is obtained by grey relation analysis.Mining practice shows that the method is a scientific and reasonable evaluation method by which the reliable evaluation index weights and evaluation results are obtained,with simple calculation process and intuitive evaluation results.It provides a new approach to explore solutions of the optimal selection of the development scheme and the plan optimization of other engineering.
