基于优势关系粗糙集与灰靶决策的矿石自燃管理应对体系

Management response system to ores spontaneous combustion based on dominance-based rough sets and grey target

针对硫化矿石自燃规律带有偏好信息的情况,为建立科学的矿石自燃规律分析体系,综合考虑矿石自燃的多种影响因素,利用基于优势关系的粗糙集理论对矿石自燃的条件属性进行约简,生成最少偏好规则集,对矿石自燃规律进行分析。研究结果表明:该方法可以充分地分析带偏好信息的矿石自燃的知识系统,不仅更加贴近于客观实际,同时简化了规律分析的复杂性,增加了生成规律的可靠性,相对于传统矿石自燃评价方法更加科学合理。

To the case that spontaneous combustion of sulfide ores with preference information, in order to establish analysis system of ores spontaneous combustion, the influential factors of ores spontaneous combustion were comprehensively considered. Dominance relation-based rough set theory was applied to reduce condition attributes of ores spontaneous combustion and generate minimum sets of preference rules. Rules of ores spontaneous combustion were analyzed. The results show that ores spontaneous combustion system with preference information can be fully analyzed by this method, which will be more objective and simple, as well as more reliable. Compared with the traditional evaluation methodology used for ores spontaneous combustion system, this method is more reasonable and scientific.
