摘要
针对采矿方案的选择由多项指标决定,而各指标之间的物理意义又各不相同,建立了基于灰靶决策与粗糙集的采矿方案优选分析体系模型.根据各方案的效果向量,选出理论最优方案,然后测算出各方案与理论最优方案的靶心距,通过比较得出实际最优方案,并根据粗糙集理论,对指标因素进行了约简,并进行了反算验证.实践证明,该模型对于采矿方案的优选与分析是切实有效的,可以进行推广使用.
Mining programs are chosen by various indicators, and the physical meanings of various indicators are different. The model of mining program optimization is built based on grey target and rough sets theory. According to effect vector of each program, the theoretical optimal mining program is chosen, then the distance between each program with the theoretical optimal program is calculated, actual optimal solution is got by comparison, index factors are reduced by rough sets theory, and then is proved. Practices show that the model for the mining program optimization and analysis is effective and can be promoted.
