| Study on quantitative prediction of track quality indexes based on grey theory |
| 摘要 |
| 軌道質(zhì)量指數(shù)是目前我國鐵路應(yīng)用的一種主要的均值評價(jià)方法，能夠真實(shí)、準(zhǔn)確地反映出軌道不平順的質(zhì)量狀態(tài)。用大機(jī)維修期內(nèi)觀測到的軌道質(zhì)量指數(shù)TQI值構(gòu)造灰色預(yù)測模型，研究數(shù)據(jù)潛在規(guī)律，對TQI隨時(shí)間的變化規(guī)律進(jìn)行研究，預(yù)測某一時(shí)刻的TQI值，從而獲得軌道質(zhì)量隨時(shí)間變化的 |
