基于区间优势可能势的模糊折衷型防洪多目标多属性决策方法

通过综合考虑防洪多目标调度中的各种风险因素,提取了影响水库群防洪需求的若干风险指标,针对防洪多目标方案集的决策优选问题,提出了一种基于区间优势可能势的模糊折衷型多属性决策方法,建立了多属性目标的决策矩阵,避免了备选方案的模糊性和不准确性。并根据区间数的可能度对各方案进行优属度排序,分别选取各属性下的正、负理想方案。另外,还提出了一种描述备选方案与理想方案差异度的优势可能势,更加精确地度量不同方案之间的优劣程度。并在此基础上,采用模糊折衷型多属性决策方法,结合不同属性的主观权重,对备选方案进行优选和排序,得到了满足实际需求的多属性决策最佳优选方案。

Interval Potential Energy Based Multi-attribute Flood Control Decision Making with Fuzzy Trade-off Method

The paper extracts some risk indexes in flood control operation with considering uncertain factors in multi-objective flood operation, the interval number based multi-attribute decision making with fuzzy trade-off method is proposed to solve the optimum seeking problem in archive set, and establishes multi-attribute decision matrix to avoid vagueness and uncertainty of candidate schemes. Considering possibility degree matrix with subjective weights, positive ideal scheme and negative ideal scheme are selected from candidate schemes. These candidate schemes are sorted by the difference degree and closeness degree of ideal schemes, and finally the satisfactory multi-attribute decision scheme is obtained by the proposed interval number based multi-attribute decision making with fuzzy trade-off method.
