为处理窄条带地下气化工艺地质适应性评价中抽象概念和定性语言的不确定性,提出了一种基于云模型的综合评价方法.首先筛选出对地下气化有影响的地质因素作为评价因子构建评价指标体系并确定其权重;其次,采用专家评分的方式构建二级评价因子云模型;而后,采用浮动云和综合云算法分别对二级评价云和一级评价云进行集结获得综合评价云;最后,以云图的方式将综合评价云与评价标准概念云进行对比,得到评价结果.结果表明:该方法的逻辑易于理解,计算过程简单,评价结果直观、可靠,适用于窄条带地下气化工艺地质适应性评价.
In order to deal with the uncertainty of abstract concept and qualitative language in the assessment of geological adaptability of narrow strip underground gasification process, a comprehensive evaluation method based on cloud model is proposed.Firstly, the geological factors influencing the underground gasification are selected as the evaluation Factor building evaluation index system and determine its weight; Second, the use of expert ratings to build a two-tier evaluation factor cloud model; and then, the use of floating clouds and integrated cloud algorithm respectively for the second evaluation cloud and first evaluation cloud to obtain a comprehensive evaluation Finally, the comprehensive evaluation cloud is compared with the concept cloud of evaluation standard to get the evaluation results. The results show that the method is easy to understand, the calculation process is simple, the evaluation results are intuitive and reliable, and it is suitable for narrow strip underground Gasification Geological Adaptability Evaluation.
