【摘要】 针对采空区处理方案中存在的多属性、不确定性等问题,构建了采空区处理多属性方案综合评价系统。基于集对分析理论,运用了对立统一的辨证观点,将确定性与不确定性因素相结合,分别建立评价集与指标集两集合的集对;利用灰色关联理论,分别对其差异度与同一度、差异度与对立度之间的关联度进行量化分析。通过实例分析,确定了采空区处理方案的等级;采用变异系数法确定评价指标的权重,选择最优方案。研究结果表明,该评价方法客观、全面、合理,可以在工程领域中应用并推广。更多还原

【Abstract】 According to multiple attributes,uncertainty and other problems in goaf treatment methods,a comprehensive evaluation system is established for multi-attribute goaf treatment in this paper.Based on set pair analysis theory,the set pair between evaluation set and index set is established by the concept of the unity of opposites,which combined the certainty and uncertainty factors.The correlation degrees between difference and identity,difference and opposite of the set pair are quantitativly analyzed by grey correlation theory.Through the example analysis,the grades of goaf treatment schemes are determined,and the variation coefficient method is further used to calculate the weights of indexes in order to choose the best scheme.The results have shown that the evaluation method is more objective,comprehensive,and reasonable and can be applied and popularized in engineering.更多还原
