摘要
以堰塞湖溃决风险取决于溃决可能性及溃决后果为研究出发点,确立了一套完备的风险等级判定体系。体系包括建立的堰塞湖风险等级判定多属性决策模型及模型参数进行敏感性分析两部分。研究应用实例表明,在快速、精准地确定堰塞湖风险等级同时,给出了保持决策等级不变的模型参数变化区间,为决策偏好问题提供了新的理论依据,为堰塞湖等级判定提供可靠的技术支撑。
Based on dam-break possibility and consequence of barrier lakes,the risk grade determination system of multiple attribute decision-making is established.The system consists of two parts: the risk grade determination model of multiple attribute decision and model-based weight sensitivity analysis.The application of risk grade determination in a barrier lake in this paper shows the ways and processes of the proposed method.The grade of the dam-break is determined rapidly and accurately,model parameter variation range for keeping the risk grade determination invariant is offered.The risk grade determination system serves as a new basis for multiple attribute decision,and offers a technological support for the risk grade determination of barrier lakes.
