【摘要】：河湖水系连通工程方案多属性多目标综合评价是河湖水系连通决策和管理迫切需要解决的基础性问题.为克服传统模糊集不能体现信息介于肯定与否定之间踌躇性的弊端,通过利用Vague集评分函数方法,建立了基于多种评分函数组合的河湖水系连通工程优选及排序的综合评价模型,并提出了基于云模型的河湖水系连通评判指标和指标权重灵敏度分析方法.以浙北引水工程为例,探讨了不同评分函数对工程方案排序的影响,对比分析了单一指标值变化和多个权重变化下不同评分函数对决策结果的鲁棒性情况.研究结果为河湖水系连通工程方案的决策和效果的合理性评估提供了一条新的研究路径.
[Abstract]:Multi-attribute and multi-objective comprehensive evaluation of river and lake system connectivity project is a basic problem that needs to be solved urgently in decision making and management of river and lake system connectivity.In order to overcome the drawback that traditional fuzzy sets can not reflect the hesitancy between positive and negative information, the method of Vague set scoring function is used.A comprehensive evaluation model for optimal selection and ranking of river and lake system connectivity engineering based on multiple scoring functions is established, and a cloud model is proposed to evaluate the connectivity of river and lake water system and the sensitivity analysis method of index weight.Taking the water diversion project in the north of Zhejiang Province as an example, the influence of different scoring functions on the ranking of project schemes is discussed, and the robustness of different scoring functions to the decision results under the change of single index value and multiple weights is compared and analyzed.The results provide a new research path for the decision making and rationality evaluation of the scheme of river and lake system connectivity engineering.
