摘要
水资源协调对实现区域可持续发展十分重要,同时考虑可见水与虚拟水,从公平、生态、效率的角度建立合理的评价指标体系,以评价区域水资源的协调状况。为提高决策群体对指标重要性评价的语义灵活性,引入了犹豫模糊数。首先,通过最小化决策群体的分歧度和评价模糊度的模型,确定决策者的权重,进而求出不同指标的权重;其次,运用TOPSIS方法集结出最终的评价结果,将提出的方法应用于评价某区域的水资源协调程度;最后,通过与直接赋予决策群体相同权重的方法作对比,验证了所提出方法的有效性。
The coordination of water resource is critical for regional long-term sustainable development.This paper developed a methodology for a comprehensive evaluation of regional water resource coordination,with visible and virtual water considered in the indicator system.To increase the flexibility of expressions,experts′judgements on indicator importance are expressed by hesitant fuzzy numbers.A minimized divergence and hesitancy degree model is established to calculate the experts′weights.Then to determine indicators′weights,a weighted average operator is used.To aggregate the final evaluation results,a TOPSIS method is adopted.The presented methodology is applied to the water resource coordination evaluation in one region in China.Finally,the effectiveness of the proposed method is verified by comparison with the method that directly assigns the same weight to the decision-making group.
