چکیده
This paper proposes a SSADT data analysis method to estimate product reliability based on time series analysis and grey theory. A RTVAR degradation time series model is proposed based on SSADT data. A grey prediction method of RTVAR model is put forward to predict product lifetime. By using the suggested method, product reliability is obtained. An example is presented as a verification of the modeling technique and estimation method. A reasonable estimation of lifetime and reliability of the product is obtained by employing the present method.
