| Holt-Winters模型在鐵路貨運量預(yù)測中的應(yīng)用(28 卷) |
| 英文標(biāo)題 |
| Application of Holt-Winters Model on Forecast of Railway Freight Traffic Volume |
| 摘要 |
| 鐵路貨運量的預(yù)測結(jié)果直接影響到鐵路運輸計劃及有關(guān)運輸政策的制定。通過提出基于Holt-Winters的鐵路貨運量預(yù)測模型，介紹了平滑系數(shù)α、β、γ的選取及初始平滑因子、遞推計算過程等關(guān)鍵預(yù)測環(huán)節(jié)，并對該預(yù)測模型設(shè)計了相應(yīng)的算法，最后利用實例驗證了Holt-Winters預(yù)測方法 |
