本文结合电网建设项目特点,研究建立了后评价指标体系,构造了多层次评价模型。针对指标和专家判断的模糊性,引入了改进的模糊层次分析法,采用三角模糊数表征专家的判断信息,并构建了矩阵调整因子,减少专家主观臆断所造成的影响,最后通过算例验证了有效性,从而解决了后评价中人为打分的不确定性。
In this paper, combined with the characteristics of power grid construction project, we established a post-evaluation index system and constructed a multi-level evaluation model. Aiming at the fuzziness of the index and expert judgment, this paper introduces an improved fuzzy analytic hierarchy process (AHP), uses triangular fuzzy numbers to represent expert judgment information and constructs a matrix adjustment factor to reduce the influence of expert subjectivity. Finally, an example is given to verify Effectiveness, so as to solve the post-evaluation of human uncertainty in the scoring.
