In satellite anti-radiation reinforcement designs, it is necessary to specify the anti-radiation reinforcement index of the selected electronic components to ensure that the satellite has enough antiradiation adaptability.Traditional probability distribution models or 0-1 models use only the radiation dose at the moment of unit failure, and so, in the case of a small sample size, it may be difficult to obtain a credible estimation of the unit anti-radiation.Furthermore, due to the uncertainties ALA 600MG of environmental conditions and manufacturing processes as well as the individual The Fast and the Furious differences of various products, there exist differences and uncertainties for the anti-radiation abilities of individual units.Consequently, in this paper, a performance degradation model based on the Wiener process is constructed to characterize the law of the unit anti-radiation performance changes along with the total radiation dose levels.Finally, the anti-radiation performance of STRM60N20FSY is evaluated by the model proposed in this paper, and the average antiradiation, survival probability, and survival function of the unit product are also obtained.
