| Abstract: | For ATS's on-station calibration and based on the historical calibration data,the Weibull model was in-troduced to describe the relations between time and measuring reliability.In the process,the old data were replaced by the new data to adjust the parameters of model.The calibration period was optimized and the time for calibration was decided.An experiment was made to testify the approach.The results show that the innovation Weibull model whose mean squared error is 2.7487 10 4 has higher prediction preci... |
