Description
Summary:For the evaluation of the construction effect of engineering projects, this study combines the comprehensive evaluation index system and fuzzy mathematical methods, and improves the calculation process of the fuzzy matrix. A fuzzy mathematical method for the evaluation of river comprehensive improvement project is proposed. The results indicate that the comprehensive evaluation of river improvement benefits needs to start from four directions: engineering benefits, ecological benefits, economic benefits, and social benefits, with target layer weights of 0.2904, 0.4755, 0.0586, and 0.1755, respectively. The expert evaluation results indicate that most evaluation indicators of the project have a rating value greater than 5 points, and some indicators have a rating value of 8 points or above. This indicates that the evaluation samples for comprehensive river improvement in the research area perform well in most indicators and achieve good improvement results. The comprehensive evaluation index belongs to the second category of fuzzy values, and the effect of the river comprehensive improvement project is relatively ideal, which is consistent with the actual evaluation. The results indicate that this method converts qualitative indicators into quantitative indicators, making the evaluation results more comparable and quantifiable, which helps to promote the effective implementation of river regulation work.
