Scheme optimum selection for dynamic control of reservoir limited water level

Dynamic control of reservoir limited water level is important to reservoir flood control operation.A reasonable limited water level can best utilize flood water resources in addition to flood control.This paper is a trial application of the fuzzy information entropy matter-element evaluation method(FIEMEM) as an optimal selection of dynamic control of limited water level.In this method,compound matter elements are established first,followed by establishment of an evaluation model and choice of the optimal scheme on the basis of fuzzy information entropy.In determining weights,a combined weighting method in game theory is adopted to combine experiential weights and mathematical weights so as to eliminate one-sidedness of the single weighting method.Finally,the feasibility of this optimization method is verified by citing dynamic control of Biliuhe reservoir limited water level as an example.

应用模糊数学方法评价福州市山仔水库水质

应用模糊数学方法对山仔水库水质进行评价 ,得出了山仔水库近六年来的水质变化趋势 ,表明近年来由于采取有效控制措施 ,山仔水库的水质逐步地得到了改善。但是水库中氮、磷的含量还较高 ,所以应进一步采取措施减少氮、磷的输入 。

不同水质评价方法对水库水质趋势分析的影响比较

对某中型水库采用单因子评价法、综合水质标识指数法和模糊数学评价法3种不同评价方法进行水质评价并作趋势分析,将结果与Kendall趋势检验分析结果作比较。得出3种方法水质趋势评价结果与Kendall趋势检验分析结果基本一致,但在水质类别判定上侧重点不同。因此,水库作水质趋势分析时可根据不同需求引进不同的水质评价方法,针对性地进行评价分析,为水库的管理治理提供更客观有效的决策依据。
