摘要
针对现有径流中长期预报模糊推理方法在实际应用中存在的问题,提出了径流中长期预报级别特征值特征展开模糊推理方法,使原有的模糊推理法得到改进,从而增强了模糊推理预报方法在径流中长期预报以及其他实际工程预报中的应用效果;并将新方法应用于大伙房水库年径流预报中,实例应用研究表明应用该方法预报中长期径流可以得到较好的预报结果.
According to the problems in the application of existing fuzzy reasoning methods for forecasting mid-long runoff,a new method,named fuzzy reasoning method of rank feature value characteristic expanding,is proposed to improve the existing fuzzy reasoning methods,which enhances the applicability of fuzzy reasoning method for forecasting mid-long runoff and other values in engineering fields. The newly proposed method is used to forecast the yearly runoff of Dahuofang Reservoir. The effectiveness of this method is verified by the case study.
