黄河下游工程建设模糊综合决策优化排序研究

Fuzzy Comprehensive Decision-making Methods in Project Construction Sequence of the Downstream Yellow River

依据黄河下游沿黄地区各类工程建设与投资计划特点,将黄河下游工程建设分为防洪堤防、引黄工程、灌溉与节水、水土保持、生态环境、河口综合开发治理、水利信息化及重点水库等8类,利用模糊决策分析理论和工程规划调查数据确定工程权重,建立模糊理想点法模型,将黄河下游按照区域特征分为15个子区,利用所建立的模型进行排序求解,得到了黄河下游水利工程建设排序计划方案。研究成果对于黄河下游沿黄地区各类水利工程建设具有指导意义。

Based on the projects construction and investment feature of the downstream of the Yellow River,the project structures were divided into flood control dike,water diversion,irrigation and water saving,soil erosion conservation and ecological projects,river mouth management and development and water resources information.Using fuzzy and decision making analysis theory and project planning investigation data,the different project weight were calculated and fuzzy ideal point model was set up.According to administrative region,the total area of the downstream of the Yellow River was divided as 14 sub-regions.Using the model to solve the project construction sequence,the sequence scheme of the water project construction was achieved.The results have an important significance for the different water projects construction of the downstream of the Yellow River.
