| Abstract: | By using the theory of gray system and time series analysis. This paper sets up a dimension-fixed and recursion-compensated gray-time series combined model for the purpose of predicating TQI value and this model can be regulated according to the error between practical data and predicted data. Applying this model into TQI prediction, it can analyze and predict the change trends of railway track condition more precisely and provide aided decisions for making railway maintenance plan. |
