摘要
粗糙模糊综合评估法是以模糊综合评估法为基础,结合粗糙集属性重要度理论,应用模糊关系合成原理,对不确定性问题进行综合性评估的一种方法。本文应用粗糙模糊综合评估法对城市地铁盾构施工中环境风险进行评估,运用粗糙集属性重要度理论进一步客观的确定评估指标权重,使得评估结果进一步趋向客观合理化,对模糊综合评估法做了一次尝试性的改进。
Rough and fuzzy comprehensive evaluation is a method ,which is based on fuzzy comprehensive evaluation method, combining with rough set attribute significance ,using fuzzy synthesis principle to estimate uncertain problems. The article estimates environmental risks in urban subway shield construction with rough and fuzzy comprehensive evaluation method, using rough set attribute significance to determinate index weight further objectively, to make assessment results more objective and reasonable, and make a tentative imprevemetlt for fuzzy comprehensive evaluation method.
