The large number of decision-making is ambiguous, multi-layered, multi-objective and non-structural decision-making groups. The application of a comprehensive evaluation method of fuzzy decision is mainly studied in this paper. On the basis of theoretical studies, Fuzzy decision-making comprehensive evaluation method is used in the performance appraisal of the College Counselors, and the evaluation index system which combines functional departments, teachers and student evaluation is built to establish the fuzzy evaluation model. What’s more, the empirical analysis shows that the comprehensive evaluation method of fuzzy decision-making in performance is effective; Fuzzy multi-objective decision making method is used in the decision-making of foundation pit dewatering program. It gives careful evaluation of the impact on precipitation by each target and quantitative description. In addition, better solutions are provided to make the decision-making of excavation works more scientific. Key words: fuzzy decision-making; weight vector; fuzzy multi-objective decision-making; decision vector 目 录 摘 要 (I) Abstract (I) 1 引言 (1) 2 模糊决策方法 (2) 2.1 模糊决策分析介绍 (2) 2.2 相对隶属度与相对隶属函数的定义 (2) 2.3 目标相对优属度概念与公式 (3) 3 高校辅导员绩效考核模糊决策综合评价模型 (4) 3.1 采用模糊决策综合评价方法考核高校辅导员绩效的步骤 (4) 3.2 实证分析 (6) 4 基坑工程的多目标模糊决策应用模型 (9) 4.1 多目标模糊决策模型 (9) 4.2 模糊二元对比确定权重 (11) 4.3 基坑降水工程评价的目标特征值矩阵 (13) 4.4 基坑决策指标的模糊二元对比研究 (14) 结束语 (16) 参考文献 (17) 致谢 (18) 1 引言 随着人类改造自然和认
