在城市地下空间开发利用适宜性评价中,传统模糊综合层次分析法过于依赖专家及个人经验,主观性过大,使得评价结果准确性难以保证.针对地下空间开发利用适宜性评价中模糊性和不确定性的特点,首先引入有限区间云模型(CM)改进层次分析法(AHP),构建CM-AHP权重赋值法,可以快速准确地完成专家群体决策的权重运算,使权重结果更加客观、可靠;其次采用云模型结合最大隶属度原则以及模糊综合评价法,分别完成对研究区地下空间开发利用的适宜性评价.结果表明:CM-最大隶属度评价模型更加适用于试验数据完善、量化分级准确的地下空间开发利用适宜性评价,其在保证评价结果科学的同时,使得评价结果本身保留了其随机性与模糊性;CM-模糊综合评价模型则适用于多决策且指标量化分级易于归一的综合评价中.
Research on the application of cloud model in the suitability evaluation of the development and utilization of underground space
In the evaluation of urban underground space development and utilization suitability,the tradi-tional fuzzy integrated hierarchical analysis method relies too much on experts and personal experience,which is too subjective and makes it difficult to guarantee the accuracy of evaluation results.In response to the characteristics of fuzziness and uncertainty in suitability evaluation,a finite interval cloud model(CM)was introduced to improve the analytic hierarchy process(AHP),and the CM-AHP weight assignment method was constructed,which can quickly and accurately complete the weight calculation of expert group decision and make the weight results more objective and reliable.Secondly,the cloud model combined with the principle of maximum subordination and the fuzzy comprehensive evaluation method were used to eval-uate the suitability of underground space in the study area.The results are as follows:CM-maximum mem-bership evaluation model is found to be more suitable for the evaluation of the suitability of underground space with perfect test data and accurate quantification and grading,which ensures the scientific evaluation results while preserving the randomness and fuzziness of the evaluation results;CM-fuzzy comprehensive e-valuation model is applicable to the comprehensive evaluation where multiple decisions are made and the in-dexes are easy to be normalized.
