【摘要】 本文介绍了秩次集对分析预测模型(R-SPA)的原理,通过具体实例预测了地下水位的变化,通过与GM(1,1)模型的预测结果进行对比。若以相对误差e≤10%合格为标准,秩次集对分析模型的预测合格率达到100%,而GM(1,1)模型预测合格率仅为50%,表明R-SPA模型在预测地下水位时具有较好的精度,是一种行之有效的方法。更多还原

【Abstract】 This paper introduces the the principle of rank-set pair analysis(R-SPA) prediction model.The groundwater tahle has heen forecasted using R-SPA,the result has also heen compared with corresponding GM(1,1) model in the present study.The predicted yield of R-SPA model reaches 100%while GM(1,1) model counterpart is only 50%if relative error standard is less thanl0%,which indicates R-SPA model is not only high precision,hut also has good prediction effect.It can he regarded as an effective technique in the groundwater tahle forecasting.更多还原
