| Abstract: | Objective The approach and procedure to fit time series with ARIMA models are discussed briefly. The application to forecast the hospital material consumption is given to help the administrative personnel perform management scientifically. Methods Proper ARIMA models are obtained with the SAS system and the effectiveness is evaluated. Results The errors of prediction to three kinds of hospital material consumption are around 10%, which show a satisfactory effectiveness. Conclusion It is both necessary and practical to apply the approach of ARIMA models in fitting time series to predict hospital material consumption within a short lead time. |
